Study of the New Permanent Magnet switched reluctance motor

I For the situation that the traditional switched reluctance motor exists output torque ripple, this article changes the motor structure, adding permanent magnets in the stator, which changes the motor into the hybrid-excitation motor and changes the magnetic circuit into the axial magnetic circuit. As a result, the magnetic circuit becomes shorter and the output torque becomes greater. Besides, because of changes in the structure, the control method using double complementary conduction suppresses torque ripple. At the same time there is no mutual inductance existing between each phases. We also discuss the speed structure and the hardware structure of the new switched reluctance motor.
