摘　　要：建立了无刷双馈调速电机稳态运行的数学模型 .用频率折算法将电机各绕组中不同频率的电量统一起来 ,获得了电机的等效电路和相量图 ,用相量图分析了控制绕组电流变化时对功率绕组的功率因数的影响 .用该模型分析了电机的稳态运行特性 ,包括稳态电磁转矩和功率关系 ,为无刷双馈调速电机设计。Steady state performance is studied for brushless doubly fed machines. The frequency of every winding is converted to the same value by application of the frequency conversion method. Equivalent circuit and the phasor diagram can be made. The phasor diagram can be used to analyze the effect of control winding current on power winding. Electromagnetic torque and power equation are also used for determining the steady state performance of brushless doubly fed machines.
