The system hardware architecture is divided into control, drive, power supply, display five blocks circuits, and magnetic coupling is used to isolate circuit boards.

系统在硬件结构上分为控制、驱动、电源、显示、电压转换五大模块电路，各电路板之间采用磁耦进行隔离。

Therefore, magnetic circuit in stator side is common, and divided into two in rotor side, thus making analysis calculation uncommon.

因此，电机的磁路定子侧为共磁路，到转子侧分成两条支路，其分析计算有一定的特殊性。
