In a single-phase hysteresis motor, the retentivity of the rotor is
Right Answer is:
High
SOLUTION
Retentivity is the ability of a material to retain a magnetic field. In a single-phase hysteresis motor the rotor of the motor is made up of a magnetically smooth chrome steel cylinder. Hence the retentivity of the rotor is high.
