Single-phase motors use capacitors to provide starting torque when power is first applied to the motor. AutomationDirect offers spare/replacement starting capacitors for our IronHorse single phase motors.
The start capacitors are no longer needed once the motors begin turning, so they are then taken out of the circuit by a centrifugal switch. We also supply spare/replacement switches for our motors. One switch model is used for the entire line of IronHorse single-phase motors.
In addition to the start capacitors and centrifugal switches, IronHorse single-phase Farm Duty motors also have run capacitors. These run capacitors allow the motors to develop higher running torque and greater efficiency, and improve the motor power factor.
Locked Rotor Overload Switches
IronHorse Farm Duty motors have a built in manual overload switch to disable the motor if the load stops the motor (locked rotor). The overload is located in the motorís junction box, and has a manual reset switch. This switch is for locked rotor only. A separate motor thermal overload must be provided.
