Torque characteristic of magnetic flux switching hybrid excitation reluctance motor

A magnetic-flux-switching hybrid-excitation reluctance motor is presented. The appropriate collocation, matching and coupling of electric excitation and permanent magnet excitation could overcome the disadvantages of large excitation loss for conventional switched reluctance motor. The electric magnetic motive force (MMF) takes two functions of excitation and control of the magnetic field of permanent magnets. On the basis of the introduction of motor structure and working principle, we use the two-dimensional finite element method to analyze the effect of various structure parameters on the motor electromagnetic torque, and compare with traditional switched reluctance motor. The static torque of a prototype was tested. Analysis results show that this kind of motor has high torque to capacity ratio.
