The area of a hysteresis loop for the magnetic material used in the rotor of a hysteresis motor should be
The area of a hysteresis loop for the magnetic material used in the rotor of a hysteresis motor should be
Right Answer is:
Very large
SOLUTION
A hysteresis motor is a synchronous motor with a uniform air gap and without DC excitation. In hysteresis motor, the hysteresis losses are very high. As the hysteresis losses are directly proportional to the area of the hysteresis loop, the hysteresis loop is very large.
