Mar 09, 2016· Activity points. 29,043. AC motors do have less torque compared to DC motors but that is usually compensated by "oversizing", about 20-30%. AC motors have good speed stability, mostly locked to the line frequency. If you are using a regulator, it is essentially reducing the effective voltage and speed is controlled by allowing greater slippage.
