A current can also be induced by constantly moving a permanent magnet in and out of a coil of wire or by constantly moving a conductor near a stationarypermanent magnet.
让永久磁铁在线圈中进出运动或让一个导体在固定的永久磁铁附近的区域移动，也会产生电流。

The structure andpermanent magnet synchronous motor model is presented, and then the mathematical model and state equation are structured based on the stationary and rotating coordinate system.
