What a capacitor
Using improperly sized capacitors can have a variety of detrimental effects on the motor. If the capacitor’s µF rating is less than the motor was designed for, the motor winding current will be too high. If the capacitor’s µF rating is higher than the motor was designed for, the motor winding current will be too low.
