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 noload.
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。

Plots the torque speed curve and power curves for given values of stall torque and noload speed.
绘制给定失速扭矩和空载速度时的力矩曲线和功率曲线，不含负荷转速。

With the pressure machine load rate below 25%, air compressor no-load running power consumption need not, and can be directly downtime, energy consumption will be zero.
