Abstract :
A description is given of a high-performance operating strategy for self-controlled synchronous motors whereby the power factors of the AC mains and motor are improved, and the torque ripples of the motor are minimized. For high-performance operation, it is crucial to operate the motor with the minimum essential value of the lead angle. A scheme for that is proposed that takes the effects of the armature resistance and thyristor turn-off time on the commutation characteristics into account. The scheme has been implemented, and its validity has been confirmed by the experimental results.<>
