Abstract
Purpose
The purpose of this paper is to present a novel steady‐state performance analysis for the hysteresis motor whose rotor ring is made of Fe‐Cr‐Co magnet steel with magnetic anisotropy.
Design/methodology/approach
In order to analyze the motor performance at synchronous pull‐out, the finite‐element method is used, where hysteresis torque is obtained from the magnetic field analysis of the hysteresis motor with the isotropic magnet. The reluctance torque due to magnetic anisotropy can be obtained by using the difference of the B‐H hysteresis‐loop area between the anisotropic and isotropic magnets.
Findings
The good agreement between computed and measured performance in an experimental motor validates the proposed analysis.
Originality/value
The proposed method is quite useful for the design and analysis of the hysteresis motor with magnetic anisotropy.
