When the flux must be reduced, however, power must be applied just to lower the field so that PM motors at high speed need some current even at no load.
当流量必须减少，但是，权力必须适用只是降低外地，这样下午电机在高速需要一些目前，即使在无负载。
The first harmonic winding and harmonic winding no-load property curve are gained when field current is change.
通过改变励磁电流的大小，得到了基波绕组和三次谐波绕组的空载特性曲线。
