Ac motor speed control

help me for circuit·AC motor (single phase 240V) speed control using sx chip or bs2.....

It would be good to know what kind of electric motor this is - shaded pole, split phase, capacitor start, etc. ? What are its power demands? All of these factors determine how best to control the speed of an electric motor. Some motor designs cannot be effectively speed controlled.

Also remember that the voltages involved can be LETHAL if you're not careful. I'm sure it goes without saying that saftey is very important, and none of us can be held responsible for what might happen if things go wrong.

Other than that, we would be glad to help!

I will be watching this post to see if you come up with something or not

You can buy motor that can be driven· by a Variable frequency Drive and you these drives for about $100.00
and the motor that depends on the horse power of the motor

The motor is quite significant. Some can be controlled by the same device that dims a light fixture. If that is the case, all you need is a digitally controlled potentiometer connected to your BasicStamp or some other variable resistance scheme that allows digital control.

Whatever you use, 240V is serious wiring. Be sure to clearly lable, fuse, and enclose in a proper housing.
