Abstract

The dynamic performance characteristics of polyphase hysteresis motors are presented. A mathematical model, based on the d-q-axis theory, for predicting the starting and synchronization processes of such motors under various operating conditions is presented. The model offers a tool for studying the dynamic stability of the hysteresis motor for small-scale disturbances such as load torque, supply voltage, and frequency. Moreover, a parametric variation is provided in order to highlight the effects of varying some of the critical quantities like hysteresis lag angle, recoil permeability, and rotor dimensions. Two experimental rotors made of 36% and 17% cobalt-steel alloys are used in this investigation. Simulations of the dynamic behaviors of the two motors are presented. There exists a reasonably close agreement between the simulated and measured results.<>
