基于圆形判断曲线的环形绕组永磁电机匝间短路故障诊断方法

Toroidal winding permanent magnet machine (TWPMM) has received widespread attention in the ultrahigh reliability field. However, it is difficult to suppress the short-circuit current within the rated value of TWPMM by relying on the impedance change of the machine itself when encountering such severe short-circuit conditions as fewer turns. Timely and accurate fault diagnosis is essential to safeg...
