In a permanent, split capacitor motor, which component provides the phase shift between the run and start windings?

• A. Run capacitor
• B. Start capacitor
• C. Centrifugal switch
• D. A small metal band

Answer: (A)

In a permanent split capacitor motor, the component that provides the phase shift between the run and start windings is the run capacitor. This capacitor is connected in series with the start winding but remains in the circuit during the entire operation of the motor, whereas the start winding is only used for a short period to help with starting the motor. The purpose of the run capacitor is to improve the motor's efficiency and performance by creating a phase shift in the current, which allows the two windings to generate an effective rotating magnetic field. This phase shift is crucial for converting electrical energy into mechanical energy and enables the motor to run smoothly and efficiently once it reaches its operating speed. In contrast, the start capacitor, although also necessary for starting the motor, is typically disconnected from the circuit after the motor has started. The centrifugal switch, which serves to disconnect the start winding, does not provide a phase shift but rather acts as a control element in the motor's operation. A small metal band does not pertain to the function of the motor components in providing phase shift and is not relevant in this context.
