摘　　要：本文从双馈交流励磁变速电机的数学模型出发,推导了有功功率、无功功率和电磁转矩的表达式,指出交流励磁容量与电机转差率的关系。Based on the mathematical model of doubly-fed AC excitation variable-speed induction machines, this paper presented the expressions of active power, reactive power and electromagnetic torque. It also gave the relationship between AC excitation capacity and the slip of electric machine.
