Influences on the speed and direction of the rotation by the phase Angle of the supply voltage, initial Angle of rotor position, PM line flux and the load torque are discussed.

同时讨论了电源合闸角、转子初始相角、磁链和负载转矩对电机转速和旋转方向的影响。

So a virtual line flux has been constructed to serve as the oriented vector instead of the line voltage vector to remove the AC voltage sensors and reduce the cost of PWM rectifiers.

采用类似于交流电机磁链观测的方法来构造一个虚拟电网磁链，可以代替电网电压作为PWM整流器矢量控制中的定向矢量，达到省去交流侧电网电压传感器，降低PWM整流器成本的目的。

What is flux? Well, flux is actually another kind of line integral.

通量是什么？，通量其实是又一种线积分。

The cast of characters building to the punch line is in constant flux, but as it happens, this is the group gathered around a kitchen table on a quiet street in Bethesda, Maryland, one night this past spring.
