Abstract: Hybrid excitation synchronous motor (HESM ) is a new type of motor, which incorporates the advantages of the permanent magnet synchronous machine (PMSM) and the electrical excitation synchronous machine (EESM), and avoids their shortcomings. Due to the air gap magnetic field of the motor being smooth and adjustable with auxiliary field windings, HESM can start with large torque and run with wide speed regulation range. Therefore, it has been widely applied in drive systems over a wide range of speeds. Firstly, the basic characteristics of the HESM were introduced, and the classification methods of the HESM were summarized in this paper. Secondly, the structure and working principle of parallel magnetic potential hybrid excitation synchronous machine were analyzed. On the basis of above analysis, the mathematical model of the hybrid excitation synchronous motor was derived. Thirdly, the control strategy of the HESM at home and abroad was further discussed and summarized. Lastly, the development trend of the HESM technology was discussed, and its application prospects were forecasted.
