Abstract

Conventional drives for switched reluctance motors (SRMs) consists in supplying DC current pulses sequentially in each stator phase according to rotor position. This square current excitation produces a pulsating torque that limits the SRM applications. This paper aims to improve the torque profile of a 8/6 SRM applying an optimized current excitation obtained using the Field Reconstruction Method (FRM). First, the SRM is modeled in a Finite Element (FE) software as a FRM requirement and further the FRM model replaces the FE model in a interactive optimization routine. Simulation results shown that shaping the excitation current appropriately, the torque ripple can be reduced in approximately 80%.
