Abstract: A novel 12 /8 pole doubly salient hybrid excited machine with asymmetric windings was proposed in this paper, and described the basic structure of the motor. Then, the magnetic circuit and finite element models were constructed. In addition, the static characteristics and armature reaction were simulated with Finite Element Analysis (FEA) software. Then summarized the motor operating point selection principles based on the armature reaction, in order to obtain a wide range of speed. The results show that DSHEM has the advantages of wide speed range, high output power, etc.
Key words: doubly salient machine; hybrid excitation; finite element analysis; speed range; armature reaction
