Introduces the work principle of Brushless Doubly-Fed Machine(BDFM).By converting frequency,makes different frequency of every winding equivalent,consequently,gets the equivalent circuit and phasor diagram of BDFM in steady state.Analyzes the relation between electromagnetic torque and power when BDFM being in steady state.At the same,simulates the rotate speed and torque of BDFM,provides the theoretical basis for the design of BDFM and control strategy study.
