Seems fairly straight forward to me?
Where does the Chinese/Russian come in?
Although that looks like a Universal motor controller not intended for induction motor.
What do you have?

This kind of controller is better to used for the light bulb or iron, and the wattage can't be 2KW, probably around 300~350W, it depends on the rated wattage of TRIAC. (many cheaper ee products from China, you should count the wattage as their claimed numbers divide by 3~5)

If you use it to control the speed of motor, it may work, but it will also causing the motor vibration phenomenon (Motor jitter).

Variable Frequency Drive (VFD) is the best choice for the speed control of motor.

chineese/russian meaning all videos about it are in there language so i cant find much out about it lol :p

the diagram says input and other says v ac.. i just dont like how normlay when i wire stuff it says input +- output -+ etc not just ''motor output''

im not sure it proper terms used on electronics?
basicly the ebay user said i can use this on my washing machiene motor,

i followed the wires to the brushes, the motor controller, etc and managed to power the coils to power it up, im making a belt sander, 2 bearing wheeld, and this is to run it.

its a small motor only 430watts 2a 50/60hz 220-240vac (sticker on side) 1100rpm
mca 52 64 148 ad12

like this



controlelr description ebay

This controller uses novel bi-directional high-power SCR. It can be very convenient adjust the current up to 25A, and solve the over current problem of the heating wire resistance is too small in the case of cooling causing good.The output voltage is adjusted anywhere between 50V-220V for use with electrical appliances. It can use to such as electric stove, water heater tune thermal, lighting dimmer, small motor speed, electric iron thermostat, and achieve dimming, thermostats, pressure regulator effect.


100% brand new and high qualityInput supply voltage: 110V ~ 250V AC

The output voltage:50V-250V(Output voltage <= Input supply voltage)

The maximum output power: 2000W

The maximum output current :25AThe voltage regulating range:50V-250V AC(Output voltage <= Input supply voltage)

The operation environment temperature:-20?-40?Dimension: Approx. 47*35*27mm

If the product you bought was from China and has Chinese text in the paper then you can upload the paper, I can translate for you, before you upload it, please compress it to as 800x600 .jpg or 1024x768 .jpg, if the resolution still not enough to see clearly then you can upload more larger.

If you have the links of that controller, please post it.

I'm afraid of that if you use it to control the motor, maybe will over load and damage the controller.

It is a Universal motor so what happens when you hook it up as per the pic in the OP?
You say you had the motor running so hook up the motor wires and the AC in and it should control the rpm.
The two bottom terminals are the AC in and the top two to the motor.
I am assuming they used a hefty Triac these are used commonly for power tools etc.
Start with the pot control at minimum.

i only payed £4 lol where the 20 come from :p?

if u can find 1 that wil work perfect under £20 link me up :) otherwise im off to wire it up and see.

onlinei foudn another pic showing me that the outside terminals are the +(live) wires,

the ones labled ''Input'' and ''motor''
so il connect the blue wires up and brown on remaining,

I guess the listing plugged in P/P to Canada!
IMO the two top ones are motor and the bottom two power, at least that is the way I would connect it!
Can't you email the seller, he is in the UK!

yeah im getting no support from him :S

ok so it fired up on minimum, and picked up speed over say 40 seconds, stil went fast.... no vibrations.,
then i turn it up nothing happens...
but if i turn it up and then power it on, it takes around 20 seconds to reach max rpm,

so,
minimum turn on = slow climb to 1100rpm
max turn on = fast climb to 1100rpm

:(

what can you link me to on ebay uk that i can buy that will work and work good :) Under £20 :D (thats where the 20 came from my max guide)
obviously cheaper the better :D il send much virtual love for the help <3

How did you hook it up?
I see one that shows the opposite side of the board and it show the top and bottom terminals common, the centre two are triac in-triac out.
What if you use a light bulb? see what the effect is.
What is the rpm of the motor across the AC line?

yeah i put it as follows

IN} Blue(live) outer edge
Brown(n) middle connection

Out} Blue(live) outer edge
brown(n) inner edge,

(it says in/out on the board)

the rpm of the motor is 1100, and im guessing it reaches this on minimum or max, it seems only to delay the time to reach max rpm

my guess is its the wrong type of controller like you said :(

No its the right style of controller for a Universal motor (AC with brushes).
The colours mean nothing to me, what did you connect the power pair to and the motor pair to?
Did you try a lamp in place of the motor?

All of the series wound washing machine motors I have seen uses closed loop speed control. They have a pulse generator so that the speed controller knows how fast the motor is rotating. The speed regulation of a series wound motor is very poor without closed loop speed control. Do not try to connect the motor directly to the mains as it will probably go so fast it will destroy itself. Your best option is to use the speed controller from the washing machine it was removed from and reverse engineer the circuit with the help of the data sheet for the speed controller IC that is used on the board. If you do not want to take that option you could buy a speed controller such as this one that is designed for the purpose. I also think that you have misread the speed rating of the motor. You said it was 1100 RPM I think it will be 11000RPM

yeah its 11,500 rps sry lol, the controller i have works i was being daft not leaving it to power up enough,

it works but not alot, id say it drops it from full speed down to id say 85% power, so it works good, but id hope to slow it to almost off

the controll board was fried which is why i got the motor :S polish washing motor from a friend,

there is no vibration in the working
its connected mains plug in, and then onto the machien

You may have better luck with one of the DC motor controllers such as KB or better still an MC-60 treadmill controller, this has the ability to ensure you start from zero rpm when powering up.
