Abstract：Permanent magnet assisted synchronous reluctance motor (PMaSynRM) has become a research hotspot in the industry in recent years, especially in the fields of household appliances, electric vehicles and industrial motors, due to its advantages of high power density, high efficiency, high cost performance and wide speed range. Based on the research status at home and abroad, this paper introduces the latest research progress in PMaSynRM's optimization design, torque boost, torque ripple suppression, mechanical strength, temperature rise distribution calculation, and fault-tolerant design. This paper also analyzes the improvement of auxiliary slot and air gap design on torque characteristics, summarizes the optimization of mechanical strength by the design of central ribs and magnetic barriers; and explains the temperature rise distribution of PMaSynRM under different working conditions, and summarizes the effects of multi-phase and winding design on the fault tolerance of PMaSynRM. Finally, considering the development trend of the motor industry, the research and development of PMaSynRM are prospected.
