摘　　要：采用增量式旋转脉冲编码器,设计了一种交流励磁电机转子电势的相位检测器,以所检测到的转子电势相位作为进行矢量控制的参考,从而获得对转矩和功率因数分别控制的优良调速性能。Based on a pulse coder, a phase detector is designed to detect the rotor inductive electromotive force of a AC-field motor The phase of the rotor inductive electromotive force is used as the reference of the vector controlling method. Thus a good speed-regulation performance is obtained because of respectively controlling of torque and powerfactor.
