摘　　要：针对永磁同步电机定子线圈匝数对电机性能影响较大的问题,提出一种理论和仿真相结合的方法分析线圈匝数对电机转矩和感应电动势的影响.首先,根据理论分析得出线圈匝数越多电机性能越好,但槽满率越高,导致嵌线难度加大,甚至会引起导线绝缘损伤;其次,通过ANSYS Maxwell软件建立电机模型,对不同线圈匝数进行二维瞬态仿真分析,获得线圈匝数与转矩、感应电动势的变化关系,选取符合电机设计要求的线圈匝数范围.为永磁同步电机定子绕组设计与优化提供理论依据.To address the problem that the number of turns of the stator coil of a permanent magnet synchronous motor has a large impact on the performance of the motor,a combination of theory and simulation is proposed to analyze the impact of the number of turns of the coils on the motor torque and increased potential.Firstly,according to the theoretical analysis,the higher the number of turns is,the better the performance of the motor is,but the higher rate of full slot makes it more difficult to embed the wire and even causes the wire insulation.Secondly,the motor model is established by ANSYS Maxwell software,and 2D transient simulation analysis is performed for different coil turns to obtain the relationship between the number of turns and the torque and induction force,and the coils that meet the motor requirements are selected.It provides an effective way to design the state winding of the permanent magnet synchronous motor and also a theoretical basis for further optimization of the permanent magnet synchronous motor.
