Method for determining stator yoke parameters of back-wound turn-to-turn short-circuit automatic fault-tolerant synchronous motor

The invention relates to the technical field of motor fault-tolerant control, and discloses a method for determining parameters of a stator yoke part of a back-wound inter-turn short circuit automatic fault-tolerant synchronous motor, which comprises the following steps of: determining the ratio of the thickness of a stator core yoke part to the circumference of a center line of the stator core yoke part according to three steps to obtain a reasonable ratio; therefore, the asymmetry degree of each phase of current after the turn-to-turn short circuit fault is greatly reduced, and the turn-to-turn short circuit automatic fault tolerance performance of the motor is ensured. 本发明涉及电机容错控制技术领域，公开了背绕式匝间短路自动容错同步电机定子轭部参数确定方法：按照三个步骤确定定子铁心轭部厚度与定子铁心轭部中心线圆周长的比值，以获得合理的比值，进而大幅降低匝间短路故障后各相电流的不对称度，保证电机的匝间短路自动容错性能。
