Replacement Parts
Single phase motors use capacitors to provide starting torque when power is first applied to the
motor. When the motor begins to turn, the start capacitor is no longer need and is taken out of the
circuit by a centrifugal switch. In addition to the start capacitor, 1-1/2 hp and larger IronHorse
single-phase motors have run capacitors to allow the motor to develop higher running torque and
greater efficiency. Run capacitors also help improve the motor power factor.
