Abstract

This chapter deals with the problems of operation of frequency-controlled high power synchronous motors with non-linear dependence of torque on shaft speed. The method contributing to minimize losses and enhance the efficiency output under working conditions has been developed. There has been formulated the law of regulating voltage and frequency at rotation speed less than the rated value, as well as criteria ensuring the maximum output under mentioned conditions. A computational example has been shown for the motor of 20 MW, 140 rpm, 11.67 Hz.
