Explanation:
The hysteresis motor is a type of synchronous motor that operates based on the hysteresis loss principle. The rotor of a hysteresis motor is made of magnetic material that can retain magnetization even in the absence of an external magnetic field. This means that the rotor will always have a residual magnetic field, which interacts with the stator magnetic field to produce torque.
The area of the hysteresis loop is a measure of the energy dissipated as heat when the magnetic material is subjected to a varying magnetic field. In the case of a hysteresis motor, the area of the hysteresis loop should be very large so that the rotor can retain a strong residual magnetic field. This is because the strength of the residual magnetic field is proportional to the area of the hysteresis loop.
Therefore, the correct answer is option C - very large.
In summary, the area of the hysteresis loop is an important factor in the design of a hysteresis motor, as it determines the strength of the residual magnetic field in the rotor. A larger area of the hysteresis loop will result in a stronger residual magnetic field and hence higher torque production.
