In a hysteresis motor, the rotor must have____________?
Correct answer: A. retentivity
- A. retentivity
- B. resistivity
- C. susceptibility
- D. none of the above
Explanation
The rotor of a hysteresis motor requires high retentivity so it retains magnetism and develops hysteresis torque as the rotating field moves past it. Resistivity and susceptibility alone do not provide this required magnetic memory.
