Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFHysteresis motors rely on the hysteresis effect in the rotor material to produce torque. The hysteresis torque is influenced by several factors, including the interaction between the stator flux and rotor flux, as well as the hysteresis characteristics of the rotor material.
The key factors that affect the hysteresis torque are:
- Stator Flux: The magnetic field produced by the stator winding.
- Rotor Flux: The magnetic field induced in the rotor due to the stator's magnetic field.
- Sine of the Hysteresis Angle (δ): The angle between the stator flux and the rotor flux, which represents the phase difference between the two magnetic fields.
The hysteresis torque (Th) is given by the product of the stator flux, rotor flux, and the sine of the hysteresis angle.
