Its voltage value should meet the requirments of ZBT 68004--90 at the minimum, nominal or maximum speed. According to the basic electromagnetic ralations of the permanent magnetic alternator, this article leads out the values of no-load potential and synchronism reactance necessary for meeting the voltage requirment. It also explores the determination of each phase serial number and attainment of the necessary reactance. At last,the conclusion resulted from the trial has been tested and verified primarily.展开更多
