Design and Analysis of a New Flux Memory Doubly Salient Motor Capable of Online Flux Control

In this paper, a new type of memory motor, namely flux memory doubly salient motor, is proposed and tested. The key is to incorporate both the online tunable permanent magnets (PMs) and magnetizing windings into a stator-permanent-magnet motor. Thus, the resulting new memory motor can offer effective and efficient flux control. The design method of the memory motor is presented in detail. By combining a piecewise-linear hysteresis model with the finite element method, the static and transient electromagnetic performances are investigated. Experimental results of the prototype are given to verify the validity of the proposed motor.
