Since the capacitor and start winding remain in the circuit, motor efficiency is higher than that of the split-phase motor. This results from an improved power factor and more even running torque. The absence of a switch or relay reduces the cost and service problems associated with those devices. The PSC motor can be used in small air conditioning and commercial units where high starting torque is not required, but good ... The electrical circuit wiring diagram is shown in Figure 15.23.
