Modeling and Simulation of Four-Phase 8/6 Switched Reluctance Motor with an Improved Winding Configuration

This paper presents a novel winding configuration which stimulates short flux loops to improve performance of four-phase 8/6 switched reluctance motor (SRM) with two phases excited. Conventional winding configuration of four-phase 8/6 SRM with two phases excited is arranged that stimulates the N-N-N-N-S-S-S-S stator pole layout mode. The presented winding configuration is arranged that stimulates the N-N-S-N-S-S-N-S stator pole layout mode which use mutual coupling to encourage several short flux paths. The simulate process of the SRM with two different winding constructers based on the Maxwell 2D software package are presented. The motorspsila static characteristics and dynamic performance have been investigated and compared. Simulation results show that the motor with improved winding configuration has an inherent advantage, and the performance of the developed motor is evaluated and validated by simulation. The results form the basis for design considerations that can optimize performance of the motor.
