摘要：
Using an elliptical approximation for the hysteresis loop, the expression of the magnetic vector potential in the anisotropic region of the rotor has been obtained both in the case of a stator surface carrying a current sheet with a sinusoidal variation, and in the case of a rotor surface at which the normal component of the flux density has a sinusoidal variation. The relationships established allow one to study the dependence of the electromagnetic torque upon the thickness of the anisotropic region made of hysteresis material, the characteristics of the hysteresis material and the degree of anisotropy. The rotor parameters have been studied and an equivalent circuit has been derived in the case of a three-phase motor.
