[Abstract]:The traditional permanent magnet brushless DC motor (brushless direct current motor, BLDCM) can not control the permanent magnet flux of permanent magnet and inherent defects, which limits its application in many high-tech fields. The paper proposes a novel doubly salient permanent magnet BLDCM. break the traditional structure principle, with the axial radial stator coil magnetic field auxiliary excitation, cancel restriction the characteristics of permanent magnetic material. The stator coil auxiliary excitation motor higher output torque characteristics by increasing the current air gap flux and armature winding. Using the finite element software for numerical analysis and verify its accuracy and effectiveness; special structure and model of the motor based on inductance, build a joint simulation model, through the way of using six phase angle guide, increase the output torque, torque ripple reduction; according to the auxiliary excitation coil of magnetic properties, the torque control of excitation loop and excitation current of hybrid armature winding. The feasibility and effectiveness of the prototype and control method of the new structure motor are verified.
