Which of the following motors one will choose to drive the rotary compressor ?
Correct answer: D. Synchronous motor
- A. D.C. shunt motor
- B. D.C. series motor
- C. Universal motor
- D. Synchronous motor
Explanation
A synchronous motor is suitable for driving a rotary compressor because it runs at constant speed and can provide efficient continuous operation. Its fixed-speed characteristic is valuable where compressor speed must remain steady.
