Never ever grab a wire you are unsure is live . At the very least touch it with the back of your hand so that if your muscles spasms it won't force you to grip it . But never touch that wire , use an insulated plier, be insulated from ground and work on insulated materials like wood or plastic
Isso é meio foda de controlar, se o motor não rodar no volume baixo, ele vai estar energizado mesmo assim, não pode queimar as bobinas da armadura ou do estator? No motor universal nem tanto, mas mais os motores monofásicos com rotor gaiola de esquilo.
Hey Everyone ! Just wanted to inform you that the ' site ' ( flipkart ) from which bought this product stated that it was an SCR based Controller but when i did some research , it turned out to be a TRIAC which i expected too but the sellers got me confused..... Although, there is not much of a difference between an SCR & a TRIAC except for the fact that an SCR allows the flow of current only in one direction but a triac allows it in both the directions. Hope it helps and appologies for the confusion. Best Regards, Mr. Electron
Thanks for the video. Could you please also share the power efficiency for this regulator? I am particularly interested to understand the power loss better input and output when it is operational. Also, does it output pure sin wave AC output?
@@pradipdas1977 No, it's not "pure sin wave AC output" because this device is JUST a command in the triac phase. So far away from that is real Motor Speed Controller. It's identical with those component from portable drilling machines.
Dude, get a disc shield for your angle grinder. If it blows up, the shards carry enough energy to rip through your tendons, joints and maybe even bones.
@@Jasmine-gw1uw Actually I have a story about my grandpa, may god look over his soul. He used to do a lot of tinkering and he pulled out a motor from a vacuum cleaner and mounted a grinding disc to it. He wanted to cut a hinge of the window and the disc blew up. Piece of the disc went through his shoulder and got stuck in a cast iron sewing machine behind him across the room. So um. Yeah, disc shields. Prety useful. P.S. He didn't die becouse of the exploding disc. Cancer did it.
Upward of that 12K rpm range and below 30K with a big fan/cutter wheel/impeller/propeller will make it sound like the grinder, high rpm’s with no weight sound sharp like the red sewing machine That’s what I was trying to figure out before, as I love these high speed motors in things, but I like that lower pitch And this is a 15-25K rpm brushed series wound universal AC/DC for anyone lost and/or confused like I was, there are a million specs and rpm/torque variants but they’re all the same “Type” of motor
I have a old air compressor motor that is 120vac i removed the pump and would like to be able to control the motor speed im unsure of the watts or amps on the motor there is not tag for the info My question is how can I find out the watts and amps and what can I use to control the motor? Can I use a dimmer for a house lighting? I'm 20 years old and love your videos and find them very educational thanks Also note the motor i have is a capacitor start i believe cause it has a centrifugal switch on
Thanks for uploading such informative video. Does this keeps ampere constant and regulate voltage only. Means does this controls voltage and keeps amps constant. Please reply... Thanks
Hi Experts, usually we control AC motor (other than Fan) by dimming voltage, the motor burns out. Isn't it the case? With this dimmer? Please advise, I'm thinking to control a sewing machine motor which runs upto 7500 RPM, tried with fan dimmer & burnt already on lowest speed
I wonder if you may use this regulator for regulate the tension of a micro wave transformer ? I plan to use it to make a Lichtenberg machine with a voltage regulation
How could this work on a fan? The induction motor's speed is not affected by the voltage, unless you're operating it below the voltage that is required to start spinning

Hi, Thanks for this video. I have ordered this one to use my 110V, 550W mixer/Grinder which is manufactured for US. My question is, will this mixer will work well with this? Or do I need to buy step down transformer?
I have a few questions. 1- Isn’t this an AC to AC voltage regulator - to lower AC voltages? 2- if it is an AC to AC regulator, then why is there a bridge rectifier in Its circuitry? 3- At +/- 4:35min you say: that this is a SCR speed controller and it only changes “the firing angle” if that’s what you said, what does that mean? And if that is not what you said, then what did you say? Please clarify for me. I bought this device, because I thought I could use it to lower 120VAC, down to 9VAC. Was I wrong? Please let me know. Thank you kindly.
Mr. Electron Sir, can I use this controller, the input is AC 220v and the output is connected to a step-down transformer input AC 110volts and output 40volts, 8 Amperes? thanks
Yes, you can, but make sure that you do not go beyond halfway mark and better to keep it on the lower side. It will work, although there will be humming. Make sure to watch my upcoming video. It is about this controller, and you are the first one to know that now beforehand 😀.
SCR only have half cycle ac so called TRIAC consist of two SCR connected in bi-directional so that to give you a full cycle of ac voltage, in other words a SCR combine with a pnp +npn transistors and thus with two pair of pnpnpe trasistors.
No... electric meter is using the amps to calculate the consumption... not the voltage...in America are using 110v...in Europe 220v ... do you think America is paying the electricity half price then Europe? 😂🤣
Nice presentation. Please tell me if this can reduce the speed of 1HP single phase or three phase motor? If yes, would it impact the initial torque? TIA.
Would that controller run on teslas plasma energy? By running ac sine wave thru a spark gap you get ac direct. Running ac direct thru a vacuum tube spark gap you get teslas plasma energy. That has the capability to run a drum motor at 3,000 rpm with less than 2amps. According to Gerard Morins work, at 9,000 rpm you can power a 3.5 kw transformer with a edrum motor at 9,000 rpms. He couldn't get a controller to turn it that fast when he seemed to go missing 6-7 years ago.
@@MrElectron thank you for your quick reply I want a 2000watt or above universal motor for concrete mixture project. Please share buy link . Thanks again
is it safe controlling for 247 running dinamo motor, my dinamo motor seems running too fast, i need to slow it down, is safe to use this controller 247 ?, have you ever try it ?
It is posible to put the speed control in hand like motorcycle using this sewing machine..bcus i need to make ebike using this sewing machine..give some idea brother
If I run my universal motor with that exact same 4000W 220V speed controller it gets up to speed but then the speeds decreases and increases slowly for some reason.
Es bueno lo electronico menos peso mas compacto pero me haria un regulafor de.voltaje como trae la soldadora electr por ejemplo no se va quemar ningun componente electronico asi como homemade yes bro thanks.Arg
Neither. A triac controls how much of each ac half cycle current can flow. If the unit is on full power it conducts for the whole of each half cycle. If it is halfway it conducts for half of each half cycle. If it is on minimum it only conducts for the last little bits.

Cool project and demonstration watching in souther part of luzon philippines
That's why I love universal motor🥰
Wow, I could really see the sound of the rpm…just like you said!
i really like that grinder
This changes the voltage!
its changing the frequency I believe . This explains how its able to change speed on those induction motors
Can i use it for Usha minion 050 self priming monoset water pump??
Does this type of controller provide enough torque to use for a wood lathe from a 220V washing machine motor?
Bravo et MERCI c'est très clair et très bien expliqué
Bises de France
Exactly was I was looking for ! ;)
does the motor controller goes very hot after using it for hours and using the motor for the washing machine as the load? thanks.

This is basically a regular fan speed controller with large capacity
I have water pump 220v/3kw/4hp/11.5amp
Which speed control unit should I take?
Sa fonctionne très bien avec un moteur machine à laver
