Dynamic modeling and performance prediction of hysteresis motors considering material properties

Hysteresis motors have attracted much attention in many aspects due to their excellent operating characteristics. However, the problem of establishing an accurate dynamic model of hysteresis motor always limits its application in closed-loop control, and the previous modeling based on constant impedance does not consider the effect of load variation on the motor characteristics, which results in low accuracy. In this paper, the influence of material properties on motor characteristics is considered based on variable impedance-based modeling, which improves the accuracy of the motor model in the full dynamic response process; on this basis, the performance of the motor can be predicted.
