The rotor and the stator are made of high quality magnetic material. There is a gap between rotor and magnetic pole, so no wear occurs during operation.

转子和定子采用优质磁性材料制成，转子和磁极之间留有一定的空气间隙，工作时无任何磨损。

At the same time, leakage magnetic coefficient of commutating pole is calculated and analyzed by magnetic flux in itself and gap at rated load.

同时，利用额定负载时换向极身中的磁通与穿过气隙的总磁通，对换向极漏磁系数进行了计算与分析。

In the gap magnetic field of pole changing synchronous machine, there would be large harmonics, which have some effects on the operating performance of the machine.

由于变极同步电机气隙磁场中将存在较大的谐波，这些磁场谐波对电机运行性能将产生一些影响。
