摘　　要：集中绕组中隔齿绕制形式能增大电机的绕组自感,实现绕组间的相互隔离,将该种绕组结构应用在双三相永磁同步电机可设计一种新的永磁同步容错电机。利用Ansoft Maxwell 2D分别为12槽10极和24槽22极双三相隔齿绕永磁同步电机建立仿真模型,针对不同绕组分布形式的电机进行有限元分析。研究两种极槽配合形式下不同接线方式的双三相隔齿绕永磁同步电机在静态磁场和瞬态磁场中的空载磁链波形、空载反电动势波形和绕组电感矩阵等特性,对比分析其电磁性能和容错性能,总结出更适合永磁同步容错电机的结构类型。Concentrated windings in the form of alternative teeth winings can increase the self-inductance of the motor windings and achieve isolation between the windings.Applying this kind of winding structure to dual three-phase permanent magnet synchronous motor can design a new permanent magnet synchronous fault-tolerant motor.Simulation model for 12-slot 10-pole and 24-slot 22-pole permanent magnet synchronous motor with dual three-phase alternative teeth wingings was established by Ansoft Maxwell 2D,and finite element simulation analysis for motors with different winding distributions was performed.The characteristics of the dual three-phase alternative teeth wingings permanent magnet synchronous motor in the static magnetic field,transient magnetic field,such as no-load magnetic flux waveform,no-load back electromotive force waveform and winding inductance matrix are studied in the two types of pole slots with different connection modes.Electromagnetic performance and fault-tolerant performance was analyzed,the suitable structure type for permanent magnet synchronous fault-tolerant motor was summarized.
