How to slow down ac motor

WebCan you slow down an electric motor? If you want to reduce rpm without compromising speed regulation then use a voltage regulator or PWM controller to lower the motor voltage. If you also want higher torque then use a gearbox (which increases torque by the same proportion as it reduces shaft rpm).Mar 16, 2560 BE WebDec 27, 2024 · When the panels of the air conditioner are removed to reveal the evaporator fan compartment, give the fan a turn by hand. The ball bearings need to be oiled with electric motor oil if the fan doesn't turn freely. If the fan turns easily, the bearings are fine and the fan capacitor might be damaged. A technician should be called for repairs.
