Abstract: The paper first analyzes the structure of BDFM. Basing on the rotor d-q reference frame of BDFM, a mathematic model was derived and an accurate simulation model was established by the Matlab/Simulink. This paper proposes a new vector control strategy for BDFM, which is verified by the simulation. The results show that this control method can achieve a wide range control of BDFM speed with good static and dynamic characteristics.
