摘要:
 针对外转子永磁同步电机弱磁能力差、高速时效率低的问题，提出了一种使用转子护套的外转子内置式永磁同步电机的电磁结构设计方法。该结构具有良好的安全性能和较宽的高效率区。通过改变转子的结构和尺寸，优化了电机的转矩脉动；从电机磁密云图中，分析了永磁体退磁的基本原因，并使用永磁体倒角和背面开槽的方法提高了永磁体的抗退磁能力。最后通过多物理场有限元仿真，对转子应力和电机效率进行分析，验证了外转子内置式电机电磁结构设计的合理性。
Abstract:
 Aiming at the problems of poor field weakening ability and low efficiency at high speed of the outer rotor permanent magnet synchronous motor, an electromagnetic structure design method of the outer rotor built-in permanent magnet synchronous motor using the rotor sheath is proposed. The structure has good safety performance and wide high-efficiency area. By changing the structure and size of the rotor, the torque ripple of the motor is optimized; from the magnetic density cloud diagram of the motor, the basic reasons for the demagnetization of the permanent magnets are analyzed, and the methods of chamfering the permanent magnets and back grooves are used to improve the anti-demagnetization ability of the permanent magnets. Finally, through the multi-physics finite element simulation, the rotor stress and motor efficiency are analyzed, and the rationality of the electromagnetic structure design of the external rotor built-in motor is verified.
