Yes, you can use voltage to control the speed of an AC motor. NOTE: top speed is ~1500 r/min because the input power is at 50 Hz. For 60 Hz motors, the 1500 r/min would be 1800 r/min. However, you can see that the speed … crafty saturday

"NettetFor example, an ac motor designed to operate at 60 Hz runs slower if the frequency drops below 60 Hz, faster if it exceeds 60 Hz. For ac motors, any change in frequency causes a proportional change in motor speed. Another example is a 5% reduction in frequency produces a 5% reduction in motor speed.
