Which of the following motors is used in tape-recorders ____________?
Correct answer: A. Hysteresis motor
- A. Hysteresis motor
- B. Reluctance motor
- C. Capacitor-run motor
- D. Universal motor
Explanation
A hysteresis motor runs smoothly and quietly at nearly constant speed, making it suitable for tape-recorders, clocks, and other timing drives. Universal motors are noisy and are used where high starting torque is needed.
