Hey guys, sorry for my long absence lately. I was late with my last video already, but I caught a bad cold directly after finishing it and couldn't do anything substantial for the next ten days. Haven't been that sick and virtually "knocked out" since my childhood. But I have recovered in the meantime and I'm back on track. Enjoy the new episode! Cheers, Gerolf
Good to hear you're feeling better. Next time, chicken soup.
The Post Apocalyptic Inventor sorry to hear that. I know how it is. I caught a bug last weekend. and still haven't gotten over it yet!

Glad you're feeling better! I wanted to say, your English is better than most people in the USA. Looking forward to your videos!
Fun, hunh? I had it for about a month and ended up on antibiotics. Still not 100%.
A very nice informative video.
We need guys like you, to teach, explain and dissect old machines, more so electrical ones.
Thank you.
I am a retired,industrial electrician. At the Mahindra factory, Mumbai, I got the chance to learn lots of new machines, their new control technology, and also new drives.
I got to learn mechanical, electronics and computing whilst I was employed.
Now in my spare time, I indulge in hobbyist work. Your videos teach me, plenty, which I enjoy.
Germans are the best engineers in the world. Thank You for this awesome video. Love the accent and the brilliant articulation.
That was the best built washer I have ever seen.
Very little electronics to go bad.
I bet it still worked.
Got to love how in old electrodomestics you could find the schematics inside. Try to find them for a modern machine...
Easy, just google for it... :D
This channel has a treasure trove of content
I had the chance to get a similar washing machine from that period. The electro-mechanical programmer was dead but I replaced it with an ATmega driving a relays board to take all the elements in charge. Those machines are not designed for programmed obseolescence. They are servicable with simple parts (standard bearings, hoses...) and the wiring diagram was even included to help you service it.
No modern machine is comparable.
I know. I took apart about three washing machines. Zero diagrams, bad screw placement, and multiple sizes of screws. They don't want you to replace parts. It's called planned obsolescence. This way you have to buy a new one .
I used to work for ICI where we had very large refrigeration compressors that were used to liquify gaseous chlorine. The ac motor was about tge size of a van and had a dc motor coupled to the same shaft. Hv was applied to the ac motor to drive the compressor. Current was induced and collected by a series of brushes or slip rings i think they were referred to. This induced current was then applied to the dc motor mounted on the same shaft in order to increase efficiency. This system was called the Kramer speed controller and was a great piece of kit. It was prone to thyristors blowing regularly if i remember correctly. This miele motor just reminded me of it. Great vid.
just googled kramer speed controler. do i get it right that the induction driven part of the rotor has coils commutator and brushes instead of being a solid piece of iron and instead of being induction motor because of eddy currents in the rotor its induction motor because of normal currents in the coils. and so then the current generated by those coils goes to a rectifier and drives DC motor?
They just don't build things this rock-solid anymore!
Very nice find!
Miele, Bosch, AEG, Westinghouse, GE, Maytag are some of the top brands that still have quality engineering that lasts a lifetime.
Two questions and a comment. What was the power rating of the induction motor, and what was its rated speed?
I am really impressed with the robustness of that washing machine. I have salvaged at least 10 washing machines here in the US... all with plastic tubs and concrete in the bottom for weight. I stopped picking them up, but I will be looking for a old one now. They all have induction motors (alone) with multiple windings for different speeds. Here they are usually (4, 6, 8 poles) 850, 1140, 1725 rpm. They are always 1/2 or 3/4 hp. Excellent video.
that's a miele but maybe you can find an old whirlpool
Wait i know you your the guy that make videos about electronics
This is very impressive for 1980''s. Never knew they had front load washers back then. That machine was definitely the end of a great era, the quality of the parts inside is unlike anything you would see today. Shame you had to take it apart. Would have been great to see it running.
Sorry for late reply/necroposting, but I have a similar machine that was made in late 70s and it had sensor buttons (stainless steel buttons which I guess react to electricity of human body). Was looking for a replacement motor because mine broke down (brush holder fell apart, and I think it eventually shorted out), which BTW is needed because a more modern Beko rusted out, ball bearing slipped out of place and there's no way to fix it because housing is made of molded plastic that is impossible to repair reliably...
Since the 50s maybe not Europe but whatever lol
I love how this is a "Waschautomat" and not a "Waschmaschine"
Thank you for validating my habit of salvaging parts from old washing machines. Not found one of these yet though.
Your tutorial on power supplies was really helpful..
Love from India 🇮🇳..
Keep up the great work..
👍👍👍
Old Miele machines are really the bomb. We had one in our family 30 years, which is a easy life expectancy.
Parts are available forever if something does go wrong.
Unquestionably the best machines to buy used.
The stainless drum would make a good outdoor planter. No danger of rusting away and self pruning for roots with the small holes around the side.
I'm certain that you can get a grooved belt replacement at a auto parts store. They're usually for the water pump/air conditioner/timing belt.
You took apart a perfectly working washing machine. I hope you are proud of yourself.
You're not kidding well built the first cover you took off you can see 😂
I still remember the ads in Holland for these. "Miele. Er is geen betere." (Miele. There is no better one. Said in a tone that brooked no argument).
Good to hear you're okay. Those washing machines are very nicely made. My mother had an old Philips one, that was called an "Electra" sold by the nationalised Electricity Board in 1980. That too was a nice old thing. It used a transistorised motor controller with tacho, and a DC "Polymotor Italia" permanent magnet motor. The drain pump motor was a standard shaded-pole one. The Miele motor is a work of art, with its field divert system for spinning, and reversable induction motor feature. Years ago a neigbour had an OLD Indesit automatic. This used a HUGE AC motor that was reversable, and had different field taps for this, and also the spinning function.
Miele is still considered “top end” of consumer appliances in Australia. Great and informative video. Thanks for making it.
Cheers Stuart 🇦🇺
an old commercial slogan (1950s/1960s) for Miele washing machines in germany: "Nur Miele, Miele sprach die Tante, die schon alle Waschmaschinen kannte" ~~ "Only Miele, Miele! said the auntie, who was well experienced with washing machines, so verry jaunty" (translation slightly modified to include a rhyme)
My ex-girlfriend's mother had one just like this and it was still functioning when she died in 2000.
It's good to have you back.
The double motor idea is very good. Universal motor for low speed and high torque. And induction motor for high speed.
Induction motor maximum speed on 50 Hz supply =
Very well done video explaining and performing the analysis on an old and very well engineered and well made washing machine. Her in America I dont think we have a company we can say this is the best washing machine. Whom ever you talk to they would give a everything from MayTag to Kenmore. In may younger years I took apart many washing machines and found they use a standard induction motor and for the logic operation using mechanical switches with a beefed up clock induction motor to rotate the know to click on various switches. As of Today more modern washing machines, I have repaired about 4 of them, mostly the main MPU board goes bad. These use universal motors.
Really great video! No apologies needed for the absence. That Miele washer is a work of great engineering and materials quality that you do not see in newer models. Both the inner and outer tubs are stainless, whereas newer models are plastic outer tubs. I also favor the older electromechanical switching. Easier troubleshooting and not susceptible to surges and spikes on the mains.
I LOVE those gloves to protect your hands and to protect from things like a capacitor discharging or whatever, but mainly just to protect the hands from scrapes.
Your knowledge is amazing! Vielen danke aus Georgia, USA!😎👍🍺
Thanks once again for another interesting video. Glad you have recovered from your cold!
The washing drums are usefull.
Top loaded ones( of decent quality).
Use as fish sump .
Frontloaded ones :drum makes good fire baskets.
The main bearing for the drum can be reused . Very sturdy. On most watching machines the washing encloser is plastic . crack the plastic around the bearing with a hammer.
The screw that goes into the iron casting is for the
Electric grounding of the drum.
Keep intact.
Very interesting to see two different motors used for the drum. Just fixed my ancient Kenmore, thankfully I didn't have to get into the motor/transmission area, yet.
This is so interesting.. I've never seen that kind of motor before. Thanks for this video
Keep the videos going one learns a lot from you thank you very much I live in Nevada Usa
What comes to washing machines, Miele is _THE_ shit.
I took apart my parents' Miele, which had served a 5-person household way over two decades, and was astonished by the build and material quality. All the balancing weights were cast steel, not (the easily cracking) concrete that modern machines use. Every single bearing still rolled as good as new. All the load-bearing bolts were 10.9(!). I still run the motor in my wheel polishing machine today. German quality and engineering at its very best.
wow a washing machine motor seems like the perfect base to construct a bandsaw from!
Thank you.
those stainless steelwasher drums make great fire pits that give off great radiant heat
Back in the day we had several old WaMa bullseye front doors. They are heavy glass and heat resistant. So in our living comune we used them to cook & bake strudel and lasagne in the oven. Not very chique, but very reliable 😎
I am still washing with a Miele Allwater that was bought in 1991. Over the years, it had a few issues but nothing a decent DIY handyman would not be able to repair. I allways lifted my wife up when the machine didn't work because she thought I was finally ready for a new one, only to be disappointed that it was something I could repair. Come to think of it, maybe that's why she divorced me...
Very nicely done. The highlighted wiring diagrams were very informative. Thank you.
Hi G, Glad you are back at it. a source for real horsepower is the swimming pool circulation motor, fish pond motors. they tend to be induction motors and they produce from 1-3 HP. maybe such exotic uses are an american habit, but maybe in germany also. If you are looking for stepper motors, look for an ancient CNC machine, a new chinese CNC motor, or salvage from a factory that has motorized assembly equipment. Cheers!
By looking at that washer again very high quality parts that washer was built to last forever
Looks like who ever had that had hard water. I have well water and my dishwasher got stained like that inside. I got some Whink Rust Stain Remover. I put that into a bottle which I could spray the inside of the dishwasher with and sprayed it lightly on the rust stains til they were gone. It did not take long at all for it to dissolve the rust stains because it is very quick with that product. It looked like new again inside. I just made sure to run it a couple times empty to get all that stuff out of it so it would be safe to eat off plates washed in there. There are other rust removers that are somewhat safer but don't dissolve the rust stains fast but they work well for people who might not want something as strong as what I like to use. I treated the sink the same way and it did brighten up some. Although the sink and dishwasher are stainless steel, they can and did get a coating of rust over time. It is just such a gradual thing you never notice it but I also had rust stains like those in my shower that were difficult to scrub off.
You would be surprised how fast that stuff takes the rust stains off things but it is one of those chemicals that you will want to avoid spilling on yourself. It contains hydroflouric acid and that is bad stuff.
My parents always used Miele washers and dryers for all the laundry our butchershop put out... in the 30+ years they were in business, they went through 3 pairs of machines... mind you, these machines didn't run 24/7, but it came close, and survived for 10 years and were replaced only because the were literally worn out.
I have bought a new Siemens washing machine in 2012, of which the manufacturer has stated in an e-mail to me that it will work 10-15 years. However, when I look at these old machines, I always ask myself whether I shouldn't rather have bought one of these (preferrably Miele) in order to not get stuck with dirty laundry in case this consumer product should ever decide to stop working. That's the problem with modern washing machines, they are produced as consumer products and are not repairable at all (like, having a plastic washing bucket instead of a metal one). I really hope I can get a used Miele to store in my basement, just because I like the redundancy, not even thinking about gutting it and reusing components.
Maybe you could build a rock tumbler with one of these motors and an old gas bottle in order to clean up old parts and restore stuff. Would be an interesting project!
i live in Egypt and we have fully working one of these
Once the drum is out of the casing, it looks like part of The International Space Station.
I have flipped the spider wheel pulley on the drum shaft to create attractive burn drums for backyard use.
Edit: The glow of the fire and embers shows through all the holes in the drum for a nice, warm effect.
Very interesting motor. I enjoyed the teardown. The robot looks promising.
that's a crazy motor. but I see why its used! cheaper and easier than a complex transmission. and controls. great video
You wouldn't need a different transmission anyway and building two motors is definitely not cheaper than a single one. The brushes will have a much longer life than in usual motors, but I don't really see what other advantage there is.
The inside baskets make excellent fire pits.
Great strip down and analysis.👍Could you now cover the cleaning, reassembly and recommissioning of the washing machine.😉
I don’t know what you do with them in Germany but in the USA the stainless steel drum is worth $75 people use them for fire rings at the beach and in their backyard
What a gorgeous piece of equipment, built to last. Great find, thanks for the fun video.
Beautiful video, I´m glad to see you are looking more into the internal circuitry of the machines. There must be a way to power the motors with the salvaged electronics themselves... Cheers!
Thanks for showing the Miele dual motor! That motor is the answer to the problem which eventually was solved by the variable frequency drive! But this motor is a very elegant, mechanical non-electronic solution to this problem.
I see you recover quite a lot of parts from washing machines, so you might be able to help me out. I have a Miele Novatronic W1918 that operates on 220 volts. The solenoid valve for filling the washing machine with water is weak and the machine shows a fault with the water supply and shuts down before starting to wash the clothes. I called the Miele office and they sent out a repairman who said that the repair would cost more than half of what a new machine would cost. Since my machine is no longer made, I would need to purchase a new model, but the salesman told me that one customer had a problem with his new washing machine and the company refused to service his machine because the washer and dryer were not a matching pair! So they want us to buy a new set and throw out perfectly good equipment! What I need to know is if the filling valves have a feedback to the computer so that ONLY their valves can be used or if the valves are simple valves that could be replaced with any other valve? If so, I would need to match the voltage of the solenoid with the line voltage provided by the machine. I have no idea what the voltage of the valves would be and if there is enough room in the machine to adapt some other valve in the place of the original one(s). Would you happen to know that information?
The repair guy also said that my drain pump is making noise and will soon fail. Can the pump be overhauled with off-the shelf parts or are they made with odd sized bearings and seals? Could I buy a pump from a different brand of washing machine and install that with adapters? The price of Miele parts is outrageous! I doubt I will want to ever buy Miele equipment again.
Thanks in advance for any information you can provide. Tearing down the machine doesn't look that difficult after watching you do it.
Very good my freind
Hi. I'd like to share my idea that I had a couple years ago and would like to see somebody to do. There are small industrial machines called tumblers or vibropolishers. They're very popular in workshops working with metal, especially for cleaning and polishing car wheels and other large parts while avoiding most of the labor And polishing can be really laborious. Ever since I saw one I kept wondering if one can make it out of an old washing machine and the kind of vibrator motor that's used for mixing paint.
You can use the remnants of a washing machine. You just need to cover the drum with polyurethane, attatch a vibrating motor and make sure the suspension doesn't rattle.
This washing machine is before the day, vector control algorithm was perfected. Now a days, all washing machine has PMSM or 3-ph induction motor. A direct drive motor (PMSM) can run at 50 RPM for washing and the same motor can spin till 1200 RPM using field weakening technique. It involves huge amount of mathematical equation solving -- few application which can explain why we studied calculus, complex number and trigonometry in school days.
Front loader from the 80’s. Very impressive
Thanks for the video.
You have shown me a lot. Much appreciated. Keep up the good work.
Nice shoes.
Now i know why Miele waschemaschinen aren' t cheaper!!
A wonderful example of quality product: in all my life i've never seen before the opening front of the chassis... only a little door for hiding the glass door.. but only for aestethical purpose, not servicing purposes!
One other wonderful and very simple help for the owner: he pulling ring near the filter hole for emergency opening of the glass door: in other brands you must open the ceilingo of the entire chassis and put a hand between drum and front panel to open the door
and that for only to show two simple point of wondering watching this video. Wow and that was made 35 years ago!! damntastic!
P.S.viel Glück für Ihre Gesundheit: Ich habe deinen ersten Kommentar erst gelesen, nachdem ich meinen Kommentar geschrieben habe (google translation: Ich hoffe es ist richtig)
Really interesting! You can use that old washer drum as a fire pit. The holes on the side make for perfect air intake and heat dissipation to the people sitting around it.
Hi Gerolf. that doublemotor is a "free energy generator" xD if you do not beliveme search in youtube xD cheers
Jonah Distl oooo shit
Jonah Distl Proof that this world is full of idiots looking for a handout.
That's a very pretty washing machine, almost a shame to strip it
A couple of those large pullys look like the makings of a bandsaw.
I've seen that on a general electric washer that had a counter block under it and it was almost very similar to a cinder block
I'm guessing you could make a single phase to 3 phase rotory converter using the hybrid universal inductive motor with a few modifications.
Would love to see a Direct Drive washing machine motor!
Those are very new though (2016) compared to the rest of the stuff this guy takes apart on the channel.
I think the earliest Direct Drives may be from mid 2000's . I only recall seeing them in that era. A lot of them would still be operating or not so cheap to purchase second hand.
My 2005 LG is a direct drive and it is still working as good as new. LG put a 10 year warranty on their Direct Drive motors, but obviously not on the rest of the machine. That may put them out of reach of a junkyard.
@@EsotericArctos We had an LG direct drive from 2000 or 2001. But this year we had to buy a new one because the drum bearing broke. Poorly we couldn't find a new bearing. While looking for
parts i discovered that it is a common problem from this series.
That could be the reason for no giving longer warranty on the rest of the machine.
What's the difference between an old washing machine and a new one? The old ones are heave af and last half a lifetime with no f'n electronics in them.... The new ones ain't!
😎😎😎Miele ey. Cement- block of German History😂💪✌️
A motor and alternator in the one unit! Love it! I would try to get one to power the other.... That would be awesome if it actually could!
I like your hand truck/dolly, I've never seen one like that here in the States.
It's a hand truck designed for climbing stairs.The German word is "Treppen-Sackkarre" and that means as much as "stair-dolly" or "stair-hand truck". In my opinion these are more useful than ordinary hand trucks. I'm sure you can get them somehow over in the US too. (Otherwise it might be a good time for me to start a hand truck business in the States ;) )
The Post Apocalyptic Inventor I love how you tell us the German names and their translation. Great fun. Good video.
Schön dass Du wieder gesund bist :)
Er war krank?
Wahrscheinlich ja .
" Haven't been that sick and virtually "knocked out" since my childhood"
So hat Er berichtet . Er ist aber wieder gesund !
Door...for use like salado bowl....or puppy plate.....good
Hi! Congratulations for the video!
I have a question: Does this fit on a eletric motorcycle project, how much HP would it be considering a weight of 150kg?
Thanks!!
I managed to remove the bearings from a similar double motor, but from the W753 washing machine model. Slight differences from your engine. Weak tension of bearings on the shaft and in the housing, noticeable play (on parts of the DC motor) Video on my channel. Now to your guide I have added a second video manual on dismantling parts. I couldn’t find any more details on these motors on the Internet.
The glass door of this machine will make a nice casserole dish, since it is temperature-hardened material and it had to stand temperatures over 100°C before. I have had those before, and they integrated well into the kitchen for anything around 180°C or more.
Yes, that was my first thought. Or maybe a heated bed for a 3D printer? It would make a great series of videos to see what could be done with all the parts of a single machine. Somebody below suggested a fire pit for the drum. The motor would be great for a sander or lathe. There's also a lot of sheet metal that could be reused if you had a spot welder.
I've known of recycling projects before that used those doors for casserole dishes, and now the fact that most washing machine doors aren't flat like they used to be really makes me hurt, because it's such a waste of perfectly good materials! But that's capitalism for you, I suppose...
old washing machines are brilliant........you can actually fix them ,unlike the sealed for life crap today
krass, wie wartungsfreundlich die Teile damals noch waren!
hi. I had a similar washing machine and I am trying to save the motor. In the part of the induction motor, where do I connect the capacitor? I missed the drawings and somebody else disassembled the machine without checking connections before. Thanks
Tolles Video
Wie immer eigentlich.
Aber irgendwie war das Bild relativ oft nicht wirklich gut fokussiert.
Und hast du mal drüber nachgedacht dir einen Schlagschrauber zuzulegen?
Ein kleiner reicht ja für sowas aber ich glaube das würde dir viel Kraft und Zeit ersparen.
Can you make some sort of motor generator with your new motor? E.g Connect induction motor to mains supply, connect a variable PSU to stator coils of brushed motor and connect a load to the brushes.
Yes, you can! That's actually called the Ward Leonard drive system. It was invented back in the late 1800's and was used to drive the DC hoist motors on elevators and cranes, among other things. Many of those old systems are still in use and in fact I service tower cranes as new as 2002 that used Ward Leonard to drive the hoist motors. It's an electrically simple system; by varying the the voltage and current on the DC generator field coils, you get very precise and smooth control of both speed and torque on the DC hoist motor. It's especially useful for lifting devices as you can easily get a large boost in speed above the rated RPM at the expense of rated torque just by weakening the field current.
There is a good solid quality to German design and engineering!
Since you call yourself the "Post Apocalyptic Inventor", you should build Zombie-Traps out of these :-D
That solid crumbly material inside the hose at 4:29 might be zeolite remnants from all the laundry detergent used in the machine.
Only *half* of Germany was ruled by Helmut Schmidt in 1982, I'm sure you remember. :)
the better half
The ex-Nazi half.
Hey hey, old treadmills also have extremely powerful and heavy motors in them
They also usually have control panels already hooked into them and what not for easy control
Why, I would go as far as to say that you could even get it wireless
The motors are also just as large as the you have salvaged video, or atleast the one I got out of my treadmill is
I think washing machine motors typically are 1/3 to 1/2 HP whereas treadmills start at 1 HP and go up.
Is it possible that the brushed motor section of the brushless motor assembly could have been used as some form of braking device - like the regenerative braking on a bus or coach? Just a thought...
Just when I'd thought I've seen everything
about electric motors, this turns up,
thank you T.P.O.I.
Great stuff as always and well explained.
The engineering put in this washing machine is amazing. It was made to last and easy repaired.
Do they still make them that way?
Then why this one was torn down instead of repaired?
Hi love ur videos. I have a question, can you use the universal motor when you rectify the mains voltage and than use a pwm controller to regulate the speed ? or do the revolutions keep going up the same as when you connect it directly to 230V Ac???
Hello, i got a quick question. i was watching a video of yours. you were reparairing a electrical connection and after you used a special white silicone to seal it. i cannot remember the name of the silicone you used, or the video. i dont know if it was MO silicone or MA or something. thanks
I have this thought.. that if I keep watching your videos I will at some point become smarter. Time will tell.. But I've passed over many a washing machines due to the fact that the internals might as well be from a UFO for all that I understand them. Basic electronics fascinates me, and I've always been a scrapper. I hope that my days of hauling everything to the scrap yard is over, and that some day I will be able to understand and repurpose the parts that work. Because I look at what you had there on the bench spinning that pulley up in a vise and all I could think about was steampunk drill press, or the platform for my new 2x72 belt grinder.. Although I'd have to build a filtered enclosure around the motor to save it from dust and shavings..
this is similar to power converters that are used for elevators
Hi mister,
Can i ask to you about tachometric controls?
I have a ISKRA (STAYER) 1990 router with a universal motor electronically controlled running from 2500- 24.000 rpm (values are similar not exact, because now, i don't have the tool under my eyes)
The speed control is realized with a ferrite ring on the main shaft and electronic circuitry (sealed in a plastic support with epoxy) I've leaved the tool in a too much moistured room for at least 15 years. (*) Now i have completely cleaned all the tool: bearings, dust, brushes and collector, rust from surfaces and i leaved the tool in a warm and dry place for all this summer before connecting electric power.
Now the tool is mechanically as if it had just left the factory, but it seems to me that the motor don't reach the maximum speed.
When I reduce the rotation speed the control circuit cuts off the power to the motor as it did when it was new, then the control circuit somehow works:
According to your experience could the ferrite ring be magnetized and lost its original magnetization?
* in this room I left two other tools: a drill and a ribbon sander, I connected them to the net a few days after retrieving them, I did not think they could have any problems ... after 10 minutes of testing the engine started to spin slower and the sander to emit smoke. That's why this time I've been waiting to connect the router, I hope I have waited enough.
I know it's hard to understand from my distance explanation but thank you anyway for your answer
I'm surprised at how little rust there was on it.
Loving the videos so far!!! So much information!
