Abstract

This paper proposed a method to compensate the unbalanced magnetic force in 12/8 switched reluctance motor. Using two-dimensional transient finite element analysis coupled with external circuits, both motor and inverter could be modeled to study the performance of motor. Airgap nonuniformity caused by eccentricity between the stator and rotor axes was found to be the main source of unbalanced magnetic force. Several connecting methods of coils were studied and it was observed from the simulation results that the currents could be adjusted in certain parallel paths and unbalanced magnetic forces could be reduced. The effects were also verified by experiment results.
