bro can u pls help me!? can i install US 52 controller 220v ac to a 110v ac gear motor?

[@MyMiniHomeWorkshop]

@@raiSTAR-sc2ey If your supply voltage is 220v then I think it would need to be converted down to 110v. I'm not 100% certain, but I think there are 110v versions of the US52 available.

[@raiSTAR-sc2ey]

@@MyMiniHomeWorkshop yes, 110v ac is available for US 52 controls. i was just hoping if i can skip the converting of power source. tnx anyways bro🙏

[@eddielane7009]

Hi l know this is an older post so I really hope you reply to me question. I wired my washing machine motor 220v and used the Chinese motor speed controller you used. All going good, BUT...... after approx of running 30 seconds or so the motor starts to act its momentarily loosing power supply kicking off on off on. Just like I would be hitting the stop button on and off. I don't have any loose connections. If I power it off it will run again for another 30 seconds or so and then repet the shuttering again. Anyway idea why. I have the motor running in reverse only to suit my project and the brushes seem good. Please help. Regards Eddie

[@MyMiniHomeWorkshop]

@@eddielane7009 About all I can suggest is you got a dud speed controller, open the box up and make sure there isn't anything loose in there.

What happen if I don't conect the tacho?. Does that affect the speed control? I mean, I don't now if my motor have's one, because it's 110V monophase and have's capacitor.

[@MyMiniHomeWorkshop]

These speed controllers are made strictly for fitting to Universal motors and need the tacho to work properly and overcome any loading applied to the motor while running

[@garage_tales]

Hi there. Thank you for the video. Really helpful. I'm trying to do the same thing to replace the burnt out motor on my lathe with a washing machine motor. All wired up correctly I believe, fitted, but the motor doesn't seem to have any torque at all. It barely turns the chuck on its own and as soon as I couch it, I can easily stop it. Have you had this problem and do you have any ideas? Thank you!

[@MyMiniHomeWorkshop]

Just the opposite, are you sure you have a Universal Motor and not the smaller capacitor start motors also used in washing machines. I had the opposite, my problem was slowing it down enough as the Universals run at around 16,000 RPM and the Capacitor start versions 1470 RPM. Thanks for watching. 👍

[@garage_tales]

@@MyMiniHomeWorkshop Hi. Thank you for your quick reply. Appreciate it 🙂 It’s definitely a universal motor, rated at 440w and 11500rpm. It spins ok on its own, but as soon as there’s a load on it, it’s slows right down. Not sure what the issue could be. I get more torque from it if I try to run it off an 18v batrery than the US-52 controller.

[@MyMiniHomeWorkshop]

@@garage_tales Perhaps you got a dud controller.

Hey mate, im not sure if im missing something but i cant see how you wired to speed controller to the motor. I understand the directional switch and AC terminals but the 6 wires coming off the controller go where? I used my multi to locate live, neutral, and earth but how do i wire in the 2 blue wire aka speed adjustment

[@MyMiniHomeWorkshop]

Unless you are trying to wire up a Universal motor from a washing machine, you most likely don't have the tachometer that is built into the back of the Universal motors, that is where the 2 blue wires go to, there is a diagram on the side of the controller that shows where everything goes. Thanks for watching. 👍

Is it possible to use 1 phase motor and a speed controller to do tapping task by spinning cw and ccw continuously

[@MyMiniHomeWorkshop]

Anything is possible, but you would need the right motor, along with some limit switches. I don't think the speed controller would stand up to continuously being switched back and forth for long. Back in my factory, we tapped 1,000's of blind holes every year, but we used a fit-for-purpose tapping chuck that had automatic reversing built into it using gears, and the motor turned clockwise all the time.

The speed arrangement is lame. I just tried to install this (400W 220V version) and the speed just jump to the max at about 30 degree of turning the potentio. It can't be slowed down nor speeding up anymore. I dont install any tachometer. Does it has anything to do with this?

[@MyMiniHomeWorkshop]

What kind of motor are you using? No tachometer would have nothing to do it I would think.

[@maulanaahmad4575]

350 W universal motor. I use this to adjust the speed of my bread mixer machine. But I have some plan to do anyway. I'll start with changing the potentiometer with different resistance value. I hope it works.

Don't forget there is some fine adjustment inside the unit

[@jcra56]

Had same problem, inverting Tach wire solved the problem

[@maulanaahmad4575]

@@jcra56 I have figured it out now. This speed regulator only work on special kind of motors that have a hall-effect dome attached on its end, The hall effect dome are already available on washing machine motors. Thats why I didn't succes in my first attempt, because my motor didn't have the dome. Later I have experimented on an induction motor which I've modified by adding a self made hall-effect dome, and it works! The hall effect dome can be easily made from a plastic bobbin, a few 0,15 mm laminated wire (or magnet wire in some country), and a magnetic rotor (I obtained this rotor from a used aquarium-pump). Just take out the magnetic rotor and make some necessary modification to attach the rotor on the back end of the induction motor shaft. Make sure it is well centered. The bobbin and the wire make a coil for about 200 windings, an then put this coil around the magnetic rotor. The two wire comes out from the winding is connected to both blue wires from the US-52 speed controller. It worked perfect!

It pays to read through the other comments sometimes, you would have found your answer, you cannot speed control a capacitor start motor. These speed controllers are for Universal Motors only.

My other question is about the feedback lines...if I dont have an rpm counter (tachiometer?) then should i connect those cable together or leave then unconnected? Thank you in advance!

[@MyMiniHomeWorkshop]

I posted this video between episodes 5 & 6. I published episode 104 yesterday, so yes I'm still around. Seems I didn't really give you the right answer to your question, on the back of the Universal Motors from washing machines, not sure about others, there is a tachometer sensor that counts revolutions of the motor, those 2 wires connect to that, and the speed controller can tell if load is being applied to it, when the revolutions start to drop it will try to compensate for the load and try and keep the revolutions as constant as it can. Your motor doesn't have one, so they are of no use to you, just leave them unconnected. 👍

The actual unit I used was a 500 watt version, as my motor has no plates or makings to tell me what it is. The 400 watt one in the video is just a stock image, I think they come in 300, 400 and & 500 versions.

Fwd & Rev Switch issues

[@royeslough]

Prior to installing with a Double pole switch it worked fine, Then after adding the double pole switch as shown in the diagram to reverse the direction, it worked in one direction then after I switched the double pole switch the other way it just made a fizzing noise and now no longer works at all. I cannot see what error I made if you have any thoughts please advise.

[@MyMiniHomeWorkshop]

@@royeslough Did you wait for the motor to completely stop before reversing it ?? They don't much care for a sudden change of direction.

[@royeslough]

Yes he motor had completely stopped and I had switched off the power at the Speed controller. I had also checked he switch wiring and there were no "shorts" between terminals. i.e. when the switch was in either direction there was only continuity between the correct terminals. The double pole switch diagram shows that only the path between the windings is reversed = Is it possible I confused one of the winding leads with the one which goes to the second brush. I do not believe I did, I believe the second brush was correctly connected to the middle terminal opposite the power input but IF I got it wrong would this cause it to work in one direction but short in the other (it is at this point my brain explodes)

[@MyMiniHomeWorkshop]

@@royeslough In that case, I don't know where you went wrong, if everything is tikkity boo then it should have worked, sorry I can't assist you further. All you are doing with the forward and rev switch is changing the polarity.

[@royeslough]

Thats fine, Two last questions please. I am getting a replacement speed controller, is there anyway to check with a multimeter that I have wired things correctly through the double pole switch before applying the power? Usually I use a continuity check to confirm I have not shorted things but as everything is connected through the motor this is not an option. Lastly I have 3 wires going inside the motor to the windings, I found two which worked (without the speed controller) but am not sure if choosing an different pair would be better/faster/stronger (Stronger is more important to me than speed, my application is to run slowly) Agin is there a method with a multimeter than would enlighten me? And thank you for all your help.
