The motor used for the compressors is____________?
Correct answer: C. capacitor-start capacitor-run motor
- A. d.c. series motor
- B. shaded pole motor
- C. capacitor-start capacitor-run motor
- D. reluctance motor
Explanation
Compressors require high starting torque and then efficient, quiet continuous operation, which is provided by a capacitor-start, capacitor-run motor. The starting capacitor supplies strong starting torque while the running capacitor improves running power factor and torque.
