"WebAn AC motor is effectively a dead short when connected to DC, and it's almost a dead short when the frequency is very low. The motor might work beautifully at 120V and 60Hz, but it will immediately burn up at 120V and 10Hz. The frequency change is what slows the motor down, and the voltage drop is what prevents the motor from burning up at that ... " - How to slow down an ac electric motor

WebOnly way to change the motor speed is by varying the AC freq. You'll do better with pulleys with your current motor, or switching to a universal motor. This. Using a system of two different sized pulleys connected with a fan belt is your best bet. A smaller motor pulley and larger table pulley setup is what is needed.

WebUnlike DC motors, an AC motor's speed cannot be controlled by modifying the input voltage.
