120vac motor running on 60vac
If i have a 120vac motor, will it work on 60vac but slower and not damage the motor? What electrical part should I use to reduce the volts?

How are you getting 60VAC and why would you want to convert TO 60VAC if the motor is made for common household 120?

And to answer your actual question: I am inclined to believe that starving it of voltage would burn up the motor. 01-22-2006 08:59 AM

Then you need a variable speed DC motor and an AC/DC inverter. I don't think running at low voltage is going to accomplish what you want to do. And I still think you'll burn the motor up trying. 01-22-2006 04:29 PM

AC motor speed is control by the frequency. Lowering the voltage will only burn up the motor. Change the pulley size or get a different motor.

You can buy AC motor controllers but they are rather pricey. They are commonly used on industrial machinery motors.
