Hey guys, new episodes about this topic are now online: Salvage a washing machine motor+transmission: ua-cam.com/video/H_JV7jTH4wU/v-deo.html Inside a Washing Machine Motor: Pinout, Teardown, Explanations and Experiments: ua-cam.com/video/CtulRqznbzI/v-deo.html
I have searched internet how to hack, modify or reuse the motor control of a direct drive washing machine with the motor (brush less three fase motor and VFC) but didn't find anything. Could you make a video? Would be great to modify and add a potentiometer and some switches to control the motor free on speed and direction. Thanks!
Yes I am so interested in this also as I have a recovered modern washing machine motor and it's power / control board and have not figured out how to use it yet. I should try to aquired the service manual for the washing machine to perhaps provide better insight as to how the motor operates.@@IdelcoEM
MORE! MORE! I don't care how long I have to sit in order to learn my friend. I am 65 and my yerning for knowledge is still the same as when I was 7. That's when I took my first radio apart to see how it worked. Magnificent video my friend. I like your ideas and can't wait to see what you come up with for control with DC supply. Next video. Please.
+Raymond Earle Ditto. I too am able to watch an hour long video. Not all Utube viewers have the attention span of a fly on amphetamines we are more like whelks ........ : )
+Dr Wobble I totally agree my friend. I am 65 and continue to learn something new everyday. Thank you very much my new friend. I have subscribed. Have a great day.
+Raymond Earle I get the same feeling now and again...just tonight I got fed up with an old notebook cooler of mine, disassembled it and repaired the section of wire that needed to be adjusted a certain way to make the fan work all the time, then replaced the bottom two large rubber strips with low heat hot glue so as to grip nicely the same way as the original two pieces of rubber that fell off.
BTW: I do NOT recommend to touch a moving transmission like this with your hands (with or without gloves). I was working on a handbrake, but couldn't finish it in time. I just wanted to put the video out, so I did this the quick and dangerous way. Please don't follow my example in this respect.
+The Post Apocalyptic Inventor this is really interesting. I'm trying to find parts for building a beltsander (making knives) and was lacking a motor. But if you get this to work I will definitely salvage my old washer :P
This guy is simply amazing. I sense a lot of consideration and sacrifice occurred to make videos such as this one. Many many thanks for this. Excellent demonstration and lesson.
Just to clear this up: I'm aware that the term "frequency of revolution" or "frequency of rotation" is an uncommon term and that it must be strange for some people (especially some American viewers) to measure this physical quantity in Hertz (Hz) instead of RPMs. In Germany the words "Drehzahl" and "Umdrehungsfrequenz" are some of the terms used for this quantity. The letter one means literally "frequency of revolution". The Hertz (Hz) (1Hz= 1s^-1) is the SI-unit for frequencies and is the correct unit to be used in countries that have the "SI" ( also known as the "Metric System"). Any reoccurring event can be measured in Hz, not just oscillations. That includes revolutions per unit time! "RPMs" is a unit that is primarily used in the English-speaking world. It is not an SI-unit and that is why I try not to use it too often. The Metric system might still be uncommon in the general population in the US, but it is the excepted standard among scientist in basically ALL countries around the world. The RPM is based on the "minute" which is totally unpractical to use in many calculations, because all SI-units are derived from the SI-base units, including the second (s) as the SI-base unit of time. Using minutes only brings unwanted conversion factors into the calculations! 1RPM = 1/60Hz => 1Hz = 60RPM When talking about dependencies between "physical quantities" I try to use the names of the quantities instead of using "units of measurement". In this way you can make a statement without restricting it to one system of measurements: 1.Example: "When you step up the volts, the RPMs rise" ( bad practice) 2. Example: "When the voltage is increased, the frequency of rotation also increases" (good practice) When you still have doubts about describing the "revolutions per time period" as a frequency, just check the definition of "RPMs" found in Wikipedia: "Revolutions per minute (abbreviated rpm, RPM, rev/min, r/min) is a measure of the frequency of rotation" en.wikipedia.org/wiki/Revolutions_per_minute I don't say that this is the only way to handle things, but the DMM that I use to measure the how fast the motor shaft is spinning puts out a reading in Hz, so why not just stick to that, instead of multiplying it by 60 all the time.
+The Post Apocalyptic Inventor theconversation.com/why-the-german-language-has-so-many-great-words-55554 I was going through old tools my father had acquired over the course of his life (he is 60 now, so he doesn't really do much with them), and I found a lot of German HSS 2-flute hand-drill bits which was in my childhood tool kit he gave me ~20 years ago at 8 or 9. Dull but no oxidation or corrosion. I took them home, sharpened them quickly on my grinder, tried them out, and said in my best AvE impression, "Gehhrmann schkookum choocher."
+The Post Apocalyptic Inventor Bravo, RPM is something of an anachronism really, most of the other time when dealing with scientific quantities we would use seconds as the time base. RPM has persisted probably largely because of the rev meter on car dashboards.
Taunter Atwill Wow an Internet Hero... The funny thing is you would never say it to my face. Also you should be cautious who you speak to on the net like that you might just find your self hacked..... I have not lived under German Occupation but again if you read anything i said that happened 70+ Years ago most of that Generation is dead or retired there children run things now that was the other point your weak mind missed..... Anyway i am done with you as clearly your hatred towards all Germans of all generations blinds you to anything you can't even have a logical discussion or argument with anyone with out your uncontrolled feelings and emotions controlling you.....Pathetic
Taunter Atwill Fucking moron i did not remove anything i said that was the guy you wrote to before you moron, everything i wrote is still there clearly your delusional hippy. You can't read English very well you might need your eyes checked. www.dailymail.co.uk/news/article-3159638/ISIS-blow-booby-trapped-BABY-teaching-militants-use-explosives-says-head-Iraqi-security-committee.html now twist that, clearly you do not read news as well. where have i denied anything i wrote i did not i stated you twisted it and got it mixed up and i even showed you where you twisted it up but your so emotional about your nazi fetish that your blind. You say I am lying about been down under lol you claim you an Elite with computers by now you should know where i am from........ You call me a bitch but your the one who is filled with emotions and most likely could not fight in real, and from the looks of your photo you look like you would be the bitch. Your a youtube troll, just so you know that is the lowest any person could ever get.
Thanks for doing these videos. I studied electronics at college ( a long time ago) and managed with that ok, but I never really managed to wrap my head around how motors, synchros and generators were used in the real world, 3-phase especially! These days. I'm more interested in making some tools for woodworking (such as sanders), so this stuff is really useful to me.
there is a electrical engineer in my family .he has never shared with me, other then he fixed cell phones for my cousin, as a hobby. your vid just showed me i know nothing.i do know it flows like water . yet i can fix cars, motorcycles,and any thing of properties and geometry.i can test millivolts yaaa. thanks for vid
The induction motor's RPM is a function of frequency and the number of poles by design; not just frequency. 2 poles at 60 hz = 3600 rpm, 4 poles at 60 hz = 1800 rpm, etc. NEMA MG1 for reference has everything you'd ever want to know about motor design. Good video by the way!
Magnificent video! The thyristor circuit seems quite bang-for-buck because it seems it can power the motor quite stably! I cant wait for the modified circuit!
Das ist genau die Videoserie worauf ich seit gut einem halben Jahr warte ^^ This is exactly tthe series of video I have been wating for since half a year. Thanks
No. 30+ minutes is fine. You found that out over time. I watched this when it came out. I just watched it again (2/20/23) since it came (back) up in my feed. Your English has gotten to where you speak it better than at least 40 percent of Americans, if not more.
Fascinating stuff TPAI. I have learned a lot about electronics thanks to you. Thank you for sharing your knowledge with us. I would certainly watch an hour long video. But its much easier for you to edit and produce content if its broken up a little.
My Kenmore front loading washer suffered a mechanical breakdown a couple years ago. The spider which is the pot metal part your test bed is spinning, and attaches to the wash drum was broken in 3 pieces. The cost of a new spider was not worth it. It's only sold as a unit with the stainless wash drum. I couldn't see putting $600 into a decade old washer. So I took it to scrap recycle. Now, I'm pissed that I didn't extract the motor before I dumped the rest of it. I did look at it but I didn't know how to run it outside the washer. Great video! I want to learn all I can about this stuff. Thanks for doing the videos.
+The Post Apocalyptic Inventor An easy Sunday morning got me here. I have been meaning to watch it since it was posted. Great video as usual, keep up the good work
+The Post Apocalyptic Inventor Showed up on my recommended viewing list as well, after watching some eevblog videos. Informative video, will definitely stick around for more. :)
Thank you again. I for one would like to see more on "Universal Motor" speed control, both a fully rectified "pulsed DC" control and a "smart" controller. Cheers.
I've seen some dodgy stuff before in videos that has made me giggle like a little boy, but this has to be the funniest, i could just imagine that wheel coming flying off around the workshop, crazy!! Great video keep them coming.
Your intro works. I didn't know your UA-cam name but listening to the intro and watching it I thought "There should be someone who invents stuff solely for the use in the apocalypse." Then your title appeared.
Thanks for this video, it is very timely. I have some big old 110v DC 1/4HP motor's and some other 220/240v AC including a huge 3HP monster; your video has given me valuable info that I can use to get these running. Cheers.
Started watching and it was an easy instant subscribe. There is a "je ne sais quoi" about your voice, accent and vocabulary that would make me interested in almost anything. I "liked" this video on my stumbleupon account, so you should see a small spike again. Thank you and I am looking forward to exploring your channel!
I have watched and enjoyed your work for some time now. A choice between FB and UA-cam got you as my second offering from youtube. Happily watched.and this shows as a recent upload from you. It helps that you are relevant, articulate, and just plain good.
Thanks for this video and the full info that you provide ... Just one thing .. Using your hand to make a load to motor through the belt is not best way ,it may harm your fingers and make high injury Good luck
Enjoyed seeing someone still doing some electronic tinkering. Nice little discussion without getting too technical. I miss being in the lab on my circuits. I will be checking out your other videos. Also I enjoyed your German accent too - its my heritage as well - though no cool accent, only west coast. RHugo here
The Post Apocalyptic Inventor Neugier ist immer gut.. So habe ich auch dein channel gefunden als ich bei AvE videos schaute.. Meine Grosseltern sind nach den 2. Weltkrieg nach Südamerika gekommen. Ich bin schon hier in Paraguay geboren.. Ich bin ganz aus der Übung Deutsch zu schreiben aber Englisch ist n bisschen komplizierter.. Sehr interesante Videos.. Mal sehen ob ich meinen alten Waschmaschienen Motor in schwung bekomme :P
Duuude even if you put out an _hour_ long video on this, I'd watch the hell out of it :D I think many, if not most people here would agree. Would this work as an idea to get feedback of speed? Power the field windings directly with the AC, but pulse the stator windings with PWM. During the "off" cycle of the PWM, use back EMF from the stator windings to measure frequency of rotation. Perhaps that could be combined with the circuit you have there?
+Azayles From what I understand, the field and stator windings have to be powered with the same kind of current (AC or DC). If they were powered differently, the attraction/repulsion between them would be unpredictable (dependent on frequency of current and revolution).
Man, I don't know how I missed your channel for this long. +1 sub! But my goodness sir, every bloody time you put "load" on the belt I had a vision of it catching your glove and redistributing your hand bits all over the shop! I know you addressed it and the comments are alive - I just wanted to agree with the "safety" crowd. All in all though, EXCELLENT video and series. You're now featured prominently on my "watch later" list.
the Cubans have cornered the market on reusing washer motors,there is even a book made available documenting what can be made using discarded household appliances. Apparently, Castro gave his blessings on publishing a booklet to be released to the general populace incouraging his fellow countrymen to show their spirit of inventivement and later had a book published showing what others had come up with. Apparently there were two published versions made,one after the other became so successful.Go figure. I do not recall the name of such books, but I am sure with a little internet surfing you will find said publications.
+The Post Apocalyptic Inventor During the Cold War the US (and as a result, the US allies) imposed an embargo on Cuba preventing the import of new cars (there was no domestic car manufacturing market within Cuba). As such the Cuban populace have had to make due with cars of a vintage nearly 50 years old. (Which, in some ways is good, because I'd imagine their trash output must be way lower than any other 'developed' nation, I digress though.) Now that the US-Cuba foreign relations have (somewhat) resumed, there is a lot of hype amongst vintage car enthusiasts within the US, as their innovative mechanics had to go to extensive lengths to keep those cars on the road in relatively stock configurations. (Instead of using hydraulic lifts, they just dig pits; instead of using fancy TIG/MIG welding setups with Argon, they have DIY stick-welding, etc. I'd be curious to see how they domestically manufacture their own primers/paints/clear coating that adhere to aluminium)
As always, great video! Hoping that you'll use the tachogenerator at some point. There's even a Motorola IC for that, the TDA1085C, but maybe you were thinking about discrete logic, which is great!
+Mattia Iezzi I have a TDA1085 and I will use it at some point, but the problem is that the TDA 1085 has been an obsolete device for many years. It is not manufactured anymore and people probably will have a hard time to buy one. At least here in Germany there are only a few private individuals who sell the rest of what they have. They usually want to have 10€ or more per chip. So it really is not my first priority to use a TDA 1085. But I'm working on a design around the TCA 785 that will probably be able to use the tacho generator's output as a feedback signal.
Excellent video! Just what I needed. I recently salvaged a washing machine motor, along with the circuit board inside it. I plan on making a multitool with it (bench grinder/buffer, belt sander, maybe other things). I'll keep these bookmarked for reference later. Thank you!
Great video, really interesting stuff but please please please stop touching the belt when it's running! One time you'll get your glove caught and a few milliseconds later you'll be missing a finger or worse.
HI MR P.A. Inventor, I see some videos online on how to change the washing machine motor into a power generator. They use an older upright type of washing machine. Can you perhaps tell me step by step how this is done with a normal washing machine?
Thank you soooooo much for combining your isolation transformer with a variac. My friend that's been helping me to plan and design my workspace and tools. My original plan was to install my own dedicated breakers, running new, thicker, better insulated power wires from the breaker box into an isolating variable transformer and finally out to multiple outlets of 110-125 and 220-250 (probably through use of taps on the secondary winding. Since I'll probably only be building my tools for the higher voltage, and using ready-made devices on the 110-125V outlets, therefore really only needing the finer adjustments on the higher voltages).And he said an isolation transformer cannot be combined with a variable transformer. It's a weird statement that I couldn't concretely disprove with Google quickly. But your creation/use of one takes care of that for me. So now we can get back on the same page designing it rather than letting such a small detail split our ideas so severely
I never realized using washing machine motors were such a pita. I figured you could use the OEM motor controller by finding a potentiometer or frequency control somewhere in the circuit.
I have virtually the same motor only it's from a whirlpool washing machine. I have the "three phase converter" hooked up but I need to know what to hook the three smaller wires coming out of the "converter" to. I want to get it on a dial like you have it so I can use it on a honey extractor, as I'm new to beekeeping and am trying to do things on a tight budget. I appreciate your help. I also have eliminated the other components in the machine by means of the diagram provided from whirlpool. Thanks again!
A year ago I assembled a bench grinder from an universal motor like this, commanded by a triac dimmer for vacuum cleaners. The dimmer's potentiometer is connected to the contacts of a relay, which is triggered by a transistor. The transistor is triggered by the tacho through another potentiometer and a diode bridge. _The relay needs a separate power source._ It's easy to build, but it's also noisy and the no-load faster speeds aren't constant. Under load though, it runs okay. I still use it.
I was thinking about adding full bridge rectifier before the thyristor controller, then the negative side would be the positive side and you should (in theory) have more power.
Running in closed loop with a controller can maintain the prime mover despite a changing load providing the load is within the power range while taking into consideration duty cycle or any reductions of output.
Verry good! Is it possible to build adrone ? Is it possible to buy a gadget drone with g sensors and sonars and "blow up" to a big one to carry one or two persons?
I wished all washing machines were made as good as the siemens, that cast bracket looks really great for experementing and perhaps inclusion into a project :-D . I enjoy your teaching method, showing the reasons for each circuit and improvements. I would imagine that hall effect sensor output would be converted to a feedback voltage that can be used to trim the motor supply, much like in switchmode power supplys :-).
+zx8401ztv Yes it's true. Many washing machines these days are much cheaper in build. Even Siemens is now producing some rather cheap machines. The old Miele machines are even more rugged than the their Siemens counterparts. There must be about 40kg or more of cast iron parts inside older Miele machines. But Siemens is the only manucaturer I know, that uses a fram that holds all the interesting parts together. And yes: The circuit that I was working on from the beginning is supposed to work just like an SMPS. Only that instead of the output voltage. it's a signal from a Hall sensor, or from the tacho generator, that is used as feedback. But at this point I'm thinking that Back-EMF is really the simplest way to properly stabilize these motors with the least effort.
+The Post Apocalyptic Inventor Why make it difficult for yourself, you can go ultra complex but its just a motor, and not a precise one at that. Simplicity has value :-D
So according to your advice I now have climbed the utility pole and made a temporary platform to complete my copy of your circuit. I'm ready to do the connection to the mains - but which end do i connect and where?
+rocketman221projects I don't remember the make and model. I have salvaged lots of cheap vacuum cleaners and they ALL had a phase fired controller. It's standard here :D
+Paul Frederick I guess that's not really a problem. Most people operate their vacuum cleaners at maximum power all the time anyway. So in most cases it's just a cheap but useless feature. But for a scavenger like me it has been a good source for simple yet reliable triac-circuits.
The Post Apocalyptic Inventor yes I would love to have access to that hardware myself. Often cheap speed controllers have lousy heatsinks in them, and the switching component tends to burn out. At least that has been my experience with the couple I have gotten my hands on. There's usually a piece of aluminum sheet metal pop riveted to the Triac, or SCR. So pretty inadequate. Also I vaguely remember there's a fundamental difference between a dimmer, and an inductive speed controller. You might want to highlight that in a video. Maybe it is a flyback diode in the circuit? I forget.
at 6:20 ...3 connections for d field windings. 1 i s just a ....tab?? what do you mean? 6:27 connect d 2 windings in series, i get that (even they have different resistances!) but i suspect it matters which end of d stator winding to connect to which end of rotor winding?? if connected d wrong way, d magn fields could oppose each other?
The problem here in North America is that our three-phase 220v circuits are only in the kitchen and the washing room for the big appliances. I've got a pile of 3-phrase 220v motors which I could easily use, in my kitchen, after pulling out the stove. They still grind those motors out because they're cheap not needing permanent magnets or regulator circuitry.Since the logic of motor field switching comes from the grid itself, we're kinda screwed. All the other motors are 120v with permanent magnets. That makes it hard to salvage from a 110v to 220v. One of the few benefits of WWII, when we rebuilt the power grid, we built it on 220v.
Thank you for the video! Is there's any way to get the schematic of the last device - the constant speed controller please? I would like to experiment with my salvaged motor a little. Thank you!
Is that high-pitched noise around 15 minutes when running from the controller or from electronic pulsing noise? I can't ever remember hearing a washing machine near that noisy.
+justfakeit888 It's the motor itself. Universal motors are very noisy. If the motor is still inside the enclosure, the sound is just a little more dampened.

+The Post Apocalyptic Inventor As far as I know, a short stick doesn't give you friction burn and slips out of your hand if its tugged away from you.

When you still have doubts about describing the "revolutions per time period" as a frequency, just check the definition of "RPMs" found in Wikipedia:

Fascinating stuff TPAI. I have learned a lot about electronics thanks to you. Thank you for sharing your knowledge with us.
I would certainly watch an hour long video. But its much easier for you to edit and produce content if its broken up a little.
My Kenmore front loading washer suffered a mechanical breakdown a couple years ago. The spider which is the pot metal part your test bed is spinning, and attaches to the wash drum was broken in 3 pieces. The cost of a new spider was not worth it. It's only sold as a unit with the stainless wash drum. I couldn't see putting $600 into a decade old washer. So I took it to scrap recycle. Now, I'm pissed that I didn't extract the motor before I dumped the rest of it. I did look at it but I didn't know how to run it outside the washer. Great video! I want to learn all I can about this stuff. Thanks for doing the videos.
Was this video shared on some platform or forum? Views have been going way up over the last few hours? Who sent you guys here?
+The Post Apocalyptic Inventor An easy Sunday morning got me here. I have been meaning to watch it since it was posted. Great video as usual, keep up the good work
+The Post Apocalyptic Inventor Showed up on my recommended viewing list, I'm not subscribed but do watch a lot of electronic stuff.
+The Post Apocalyptic Inventor Showed up on my recommended viewing list as well, after watching some eevblog videos. Informative video, will definitely stick around for more. :)
+The Post Apocalyptic Inventor recommended viewing list
+The Post Apocalyptic Inventor UA-cam recommended it!
Thank you again. I for one would like to see more on "Universal Motor" speed control, both a fully rectified "pulsed DC" control and a "smart" controller.
Cheers.
I've seen some dodgy stuff before in videos that has made me giggle like a little boy, but this has to be the funniest, i could just imagine that wheel coming flying off around the workshop, crazy!! Great video keep them coming.
Your intro works. I didn't know your UA-cam name but listening to the intro and watching it I thought "There should be someone who invents stuff solely for the use in the apocalypse." Then your title appeared.
I love how clearly you describe and explain things
Jeremy Felding said I should check out your videos on motors…he was right, Thank You.
Thanks for this video, it is very timely. I have some big old 110v DC 1/4HP motor's and some other 220/240v AC including a huge 3HP monster; your video has given me valuable info that I can use to get these running. Cheers.
Started watching and it was an easy instant subscribe. There is a "je ne sais quoi" about your voice, accent and vocabulary that would make me interested in almost anything. I "liked" this video on my stumbleupon account, so you should see a small spike again. Thank you and I am looking forward to exploring your channel!
I used a wrong terme when describing the setup. The belt is not "toothed" since it doesn't have any "teeth" :D
+The Post Apocalyptic Inventor The correct term is apparently "Ribbed", just for future reference. Great video.
+SlocketSeven Or grooved. Years ago i changed my old Gorenje belt, it was listed roughly as 'high speed grooved belt'.
+SlocketSeven ribbed for her pleasure?
a multi vee belt
+Tim Trial Usual term for that type of belt is Polly Vee.
I have watched and enjoyed your work for some time now.
A choice between FB and UA-cam got you as my second offering from youtube. Happily watched.and this shows as a recent upload from you.
It helps that you are relevant, articulate, and just plain good.
Thanks for this video and the full info that you provide ...
Just one thing ..
Using your hand to make a load to motor through the belt is not best way ,it may harm your fingers and make high injury
Good luck
Enjoyed seeing someone still doing some electronic tinkering. Nice little discussion without getting too technical. I miss being in the lab on my circuits. I will be checking out your other videos. Also I enjoyed your German accent too - its my heritage as well - though no cool accent, only west coast. RHugo here
Auf dieses Video wartete ich schon ne Weile.. Grüsse aus Paraguay (Südamerika)
+Ferdinand Schröder Entschuldige meine Neugier, aber bist du nach Paraguay ausgewandert, oder machst du gerade eine Reise?
The Post Apocalyptic Inventor
Neugier ist immer gut.. So habe ich auch dein channel gefunden als ich bei AvE videos schaute.. Meine Grosseltern sind nach den 2. Weltkrieg nach Südamerika gekommen. Ich bin schon hier in Paraguay geboren..
Ich bin ganz aus der Übung Deutsch zu schreiben aber Englisch ist n bisschen komplizierter..
Sehr interesante Videos.. Mal sehen ob ich meinen alten Waschmaschienen Motor in schwung bekomme :P
I'm so impressed with how intelligent you are and enjoy your videos.
Duuude even if you put out an _hour_ long video on this, I'd watch the hell out of it :D I think many, if not most people here would agree.
Would this work as an idea to get feedback of speed? Power the field windings directly with the AC, but pulse the stator windings with PWM. During the "off" cycle of the PWM, use back EMF from the stator windings to measure frequency of rotation. Perhaps that could be combined with the circuit you have there?
+Azayles From what I understand, the field and stator windings have to be powered with the same kind of current (AC or DC). If they were powered differently, the attraction/repulsion between them would be unpredictable (dependent on frequency of current and revolution).
Man, I don't know how I missed your channel for this long. +1 sub!
But my goodness sir, every bloody time you put "load" on the belt I had a vision of it catching your glove and redistributing your hand bits all over the shop! I know you addressed it and the comments are alive - I just wanted to agree with the "safety" crowd.
All in all though, EXCELLENT video and series. You're now featured prominently on my "watch later" list.
Really nice educational video, I like the way you present the theory of operation. Thank you.
Great video. Back-EMF controllers have eluded my own personal study. I look forward to the next video.
I can see a nice 2×72" belt grinder being built with that rigid cast iron frame, it almost looks designed for one
the Cubans have cornered the market on reusing washer motors,there is even a book made available documenting what can be made using discarded household appliances. Apparently, Castro gave his blessings on publishing a booklet to be released to the general populace incouraging his fellow countrymen to show their spirit of inventivement and later had a book published showing what others had come up with. Apparently there were two published versions made,one after the other became so successful.Go figure. I do not recall the name of such books, but I am sure with a little internet surfing you will find said publications.
+scott firman Yeah they also made a documentary about those guys.
Necessity is the mother of invention.
+The Post Apocalyptic Inventor During the Cold War the US (and as a result, the US allies) imposed an embargo on Cuba preventing the import of new cars (there was no domestic car manufacturing market within Cuba). As such the Cuban populace have had to make due with cars of a vintage nearly 50 years old. (Which, in some ways is good, because I'd imagine their trash output must be way lower than any other 'developed' nation, I digress though.) Now that the US-Cuba foreign relations have (somewhat) resumed, there is a lot of hype amongst vintage car enthusiasts within the US, as their innovative mechanics had to go to extensive lengths to keep those cars on the road in relatively stock configurations. (Instead of using hydraulic lifts, they just dig pits; instead of using fancy TIG/MIG welding setups with Argon, they have DIY stick-welding, etc. I'd be curious to see how they domestically manufacture their own primers/paints/clear coating that adhere to aluminium)
That rugged cast iron frame are just perfect for belt sander
Thanks for the information presented here about universal motors, and the great youtube channel.
You sound a little bit like Marvin Martian. No insult intended. We like it.
No, Dr. Strangelove !
Hi, this is inspiring, I'm curious to see what comes next.
Long videos are not a problem, coming from you.
Keep on trucking ! (from France)
looks like that setup would work really well for a band saw. Or, like you said, a sander. thank you for the video
As always, great video!
Hoping that you'll use the tachogenerator at some point. There's even a Motorola IC for that, the TDA1085C, but maybe you were thinking about discrete logic, which is great!
+Mattia Iezzi I have a TDA1085 and I will use it at some point, but the problem is that the TDA 1085 has been an obsolete device for many years. It is not manufactured anymore and people probably will have a hard time to buy one. At least here in Germany there are only a few private individuals who sell the rest of what they have. They usually want to have 10€ or more per chip. So it really is not my first priority to use a TDA 1085. But I'm working on a design around the TCA 785 that will probably be able to use the tacho generator's output as a feedback signal.
Excellent video! Just what I needed. I recently salvaged a washing machine motor, along with the circuit board inside it. I plan on making a multitool with it (bench grinder/buffer, belt sander, maybe other things). I'll keep these bookmarked for reference later. Thank you!
Love the last circuit, simple and elegant. Thanks
Genialer Kanal, endlich hab ich Dich entdeckt :-) LG, Berrit Andersen
Long videos are great! Really looking forward to the next one!
Great video, really interesting stuff but please please please stop touching the belt when it's running! One time you'll get your glove caught and a few milliseconds later you'll be missing a finger or worse.
This proves that knowledge and wisdom are sometimes mutually exclusive. It is unwise to subject one's hand to such danger!
NSA will be coming for you. Very creative. Thanks.
HI MR P.A. Inventor,
I see some videos online on how to change the washing machine motor into a power generator. They use an older upright type of washing machine. Can you perhaps tell me step by step how this is done with a normal washing machine?
+Telephone Telephone Please give me some links to those videos. Otherwise I won't be able to tell you what exactly is happening there.
Thank you soooooo much for combining your isolation transformer with a variac. My friend that's been helping me to plan and design my workspace and tools. My original plan was to install my own dedicated breakers, running new, thicker, better insulated power wires from the breaker box into an isolating variable transformer and finally out to multiple outlets of 110-125 and 220-250 (probably through use of taps on the secondary winding. Since I'll probably only be building my tools for the higher voltage, and using ready-made devices on the 110-125V outlets, therefore really only needing the finer adjustments on the higher voltages).And he said an isolation transformer cannot be combined with a variable transformer. It's a weird statement that I couldn't concretely disprove with Google quickly. But your creation/use of one takes care of that for me. So now we can get back on the same page designing it rather than letting such a small detail split our ideas so severely
Very interesting. I have a motor from a washer but not the rest of the parts in your video.
Tanks for uploading.
this video is just what i was lookking for
I cant wait to see te way to build the propper motor reagulator.
I never realized using washing machine motors were such a pita. I figured you could use the OEM motor controller by finding a potentiometer or frequency control somewhere in the circuit.
Perfect, sehr gutes Video Genosse. Gruesse aus Kanada.
+ObsessionPC Genosse? Germans don't do communism no more!
i enjoy the longer more detailed videos
Love your videos. I learn a lot from them. Thank you!
I have virtually the same motor only it's from a whirlpool washing machine. I have the "three phase converter" hooked up but I need to know what to hook the three smaller wires coming out of the "converter" to. I want to get it on a dial like you have it so I can use it on a honey extractor, as I'm new to beekeeping and am trying to do things on a tight budget. I appreciate your help. I also have eliminated the other components in the machine by means of the diagram provided from whirlpool. Thanks again!
Good job! Professional video presentation...nicely explained and ably demonstrated. Thank you.
A year ago I assembled a bench grinder from an universal motor like this, commanded by a triac dimmer for vacuum cleaners.
The dimmer's potentiometer is connected to the contacts of a relay, which is triggered by a transistor. The transistor is triggered by the tacho through another potentiometer and a diode bridge. _The relay needs a separate power source._
It's easy to build, but it's also noisy and the no-load faster speeds aren't constant. Under load though, it runs okay. I still use it.
+soupflood I'm so happy that you got this of your chest, no go back to the drawing board and make the speeds constand under all conditions dammit.
Taunter Atwill You will need a programmed microcontroller then, unfortunately.
So? Is it expensive?
Taunter Atwill Not at all, but programming it requires some knowledge that I don't have. I know, I should learn it, and I will - sooner or later.
Excellent video! Thought i'd get bored when i saw 18 mins, but i didn't haha... :P
Very nice. Keep up the good work! Looking forward to seeing the next video.
Jeremy Fielding reminded me about your channel. On 17Dec2019.
Thanks for the good videos.
sehr gut gemacht,vielen dank!!!
Your intro is just sooooo charming
yrs ago i just used the original set up...and attached a round saw blade..therefore using an old table I had a superb rip saw...
Yes. I want / need to learn this. Want to use for wind,solar power. Thanks for the info.
I was thinking about adding full bridge rectifier before the thyristor controller, then the negative side would be the positive side and you should (in theory) have more power.
Sooooo cool ! I wait the next video, I really want re-use these motors to make my machines ! Thanks !
Thanks, Great video as usual, looking forward to the next ones
Do you have a video on using a motor of some kind attached to a saw blade for making ones own Sawmill perhaps?
all you demonstrated was that the motor is usable.
what ideas can you present for actually reusing it in an applied manner?
Age of Reason a table fan.
Ooooooh
a very powerful table fan, lol, but yes
What about the tree-phase motors? They use switching mosfet's to generate the correct frequency using the 120VAC line, turning it into DC first.
Running in closed loop with a controller can maintain the prime mover despite a changing load providing the load is within the power range while taking into consideration duty cycle or any reductions of output.
Cool Video in well understandable european english,love to learn about this Engines all,good Luck,dont get blitzed to often,hehe..
Verry good! Is it possible to build adrone ? Is it possible to buy a gadget drone with g sensors and sonars and "blow up" to a big one to carry one or two persons?
I wished all washing machines were made as good as the siemens, that cast bracket looks really great for experementing and perhaps inclusion into a project :-D
.
I enjoy your teaching method, showing the reasons for each circuit and improvements.
I would imagine that hall effect sensor output would be converted to a feedback voltage that can be used to trim the motor supply, much like in switchmode power supplys :-).
+zx8401ztv Yes it's true. Many washing machines these days are much cheaper in build. Even Siemens is now producing some rather cheap machines. The old Miele machines are even more rugged than the their Siemens counterparts. There must be about 40kg or more of cast iron parts inside older Miele machines. But Siemens is the only manucaturer I know, that uses a fram that holds all the interesting parts together.
And yes: The circuit that I was working on from the beginning is supposed to work just like an SMPS. Only that instead of the output voltage. it's a signal from a Hall sensor, or from the tacho generator, that is used as feedback.
But at this point I'm thinking that Back-EMF is really the simplest way to properly stabilize these motors with the least effort.
+The Post Apocalyptic Inventor
Why make it difficult for yourself, you can go ultra complex but its just a motor, and not a precise one at that.
Simplicity has value :-D
And there's me thinking all you had to do was feed some power to a motor ! Not so.. Excellent tuition and education.. Thank you very much
So according to your advice I now have climbed the utility pole and made a temporary platform to complete my copy of your circuit. I'm ready to do the connection to the mains - but which end do i connect and where?
What kind of vacuum cleaner did you take that speed controller out of?
Every one I have taken apart just connects the motor directly to the mains.
+rocketman221projects I am beginning to get the idea that they have much nice stuff in Germany than we have here.
+rocketman221projects I don't remember the make and model. I have salvaged lots of cheap vacuum cleaners and they ALL had a phase fired controller. It's standard here :D
The Post Apocalyptic Inventor
In the US vacuum cleaners just have an ON-OFF switch. So they're all, or nothing.
+Paul Frederick I guess that's not really a problem. Most people operate their vacuum cleaners at maximum power all the time anyway. So in most cases it's just a cheap but useless feature. But for a scavenger like me it has been a good source for simple yet reliable triac-circuits.
The Post Apocalyptic Inventor
yes I would love to have access to that hardware myself. Often cheap speed controllers have lousy heatsinks in them, and the switching component tends to burn out. At least that has been my experience with the couple I have gotten my hands on. There's usually a piece of aluminum sheet metal pop riveted to the Triac, or SCR. So pretty inadequate. Also I vaguely remember there's a fundamental difference between a dimmer, and an inductive speed controller. You might want to highlight that in a video. Maybe it is a flyback diode in the circuit? I forget.
Enjoyed the vid. Thank you for making this an the others.
at 6:20 ...3 connections for d field windings. 1 i s just a ....tab?? what do you mean? 6:27 connect d 2 windings in series, i get that (even they have different resistances!) but i suspect it matters which end of d stator winding to connect to which end of rotor winding?? if connected d wrong way, d magn fields could oppose each other?
Saw name, saw thumbs, subscribed
The problem here in North America is that our three-phase 220v circuits are only in the kitchen and the washing room for the big appliances. I've got a pile of 3-phrase 220v motors which I could easily use, in my kitchen, after pulling out the stove. They still grind those motors out because they're cheap not needing permanent magnets or regulator circuitry.Since the logic of motor field switching comes from the grid itself, we're kinda screwed.
All the other motors are 120v with permanent magnets. That makes it hard to salvage from a 110v to 220v.
One of the few benefits of WWII, when we rebuilt the power grid, we built it on 220v.
I would like to use a motor from a washing machine as a gate openner, to you think the would be sufficient and reliable?
Very well explained my friend.
thanks! Suscribed, project from salvaged common appliances is what I'm looking for (greeting from France)
Have you ever looked at some which have inverter drive motors?
thank you so much for this video I am really looking forward to see the second part - full wave circuit.
Your're German accent is fading. Good video BTW.
Excellent information.
Exerlent recicle Sir !
sir could your motor be used for generating power maybe for a water wheel ect ??
kind Regards
snell
What a Great site...Thank you brother...
you could use the motor to increase the temperature in forges, modifying the motor to include a fan which blows into the fire.
Wow. Good video. You're one smart dude. Thanks for the video. Subscribed and liked your video. Good explanations. 👍
Thank you for the video! Is there's any way to get the schematic of the last device - the constant speed controller please?
I would like to experiment with my salvaged motor a little.
Thank you!
Do you have a video with the basics on electric motors and controllers? such as DC vs AC motors?
Is that high-pitched noise around 15 minutes when running from the controller or from electronic pulsing noise? I can't ever remember hearing a washing machine near that noisy.
+justfakeit888 It's the motor itself. Universal motors are very noisy. If the motor is still inside the enclosure, the sound is just a little more dampened.
Hi. Thanks for video great! can I use it with 24 volt or more for bike it scooter?
Hi, can the motor be used for plastic shredding ?
Very cool video; thanks.
