This motor is a new "high efficiency" replacement. It is a permanent split capacitor (PCS) design for the previously produced shaded pole design. This motor will use less electricity (lower AMP draw) but produce enough torque for the fan to do the work that is required. To make installation similar, we have provided the capacitor with the motor so that you only have to work with similar leads to the original motor. PSC motors are an excellent choice to replace shaded pole motors to improve the electrical efficiency of most systems. We encourage you to consider PSC motors as an energy saving alternative in your repair work.
