After providing a phase shift in a permanent split capacitor motor, what remains in the circuit?

• A. Regulator
• B. Electrolytic capacitor
• C. Pressure switch
• D. Run capacitor

Answer: (D)

In a permanent split capacitor (PSC) motor, the purpose of the capacitor is to create a phase shift in the current flowing to the motor's windings. This phase shift allows the motor to generate a rotating magnetic field, which is essential for the operation of the motor. After the phase shift has been introduced through the capacitor, the component that continues to be part of the circuit is the run capacitor. The run capacitor remains in the circuit during the motor's operation and helps maintain an efficient performance by continuously providing the necessary phase shift to the currents in the motor windings. This ongoing presence of the run capacitor is vital for the motor's efficiency and to help ensure that it operates smoothly under varying load conditions. The other options do not remain part of the circuit in the same way. A regulator or a pressure switch are typically not components that would function as part of the motor's mechanism to create a phase shift. An electrolytic capacitor, while it may be used in some applications, is not the same as the run capacitor which is specifically designed for continuous operation in a PSC motor. Therefore, recognizing that the run capacitor is the component that stays in the circuit to facilitate ongoing phase shifting is crucial in understanding how PSC motors operate effectively.
