Direct Torque Control of a Novel Modular Structure Hybrid-Excitation Switched Reluctance Motor Based on Vector Control

in this paper, a novel 3-phase 6/4-pole modular hybrid excitation switched reluctance machine is proposed. Compared with conventional switched reluctance motor, its stator and rotor are both modular structures, which is good for weakening the influence of saturation, decreasing the wind loss and cost. The main size parameters of this motor are optimized by 2D finite-element method. The dynamic performance, static magnetic and torque characteristics of this novel machine are also simulated. The direct torque control strategy based on vector control is compared and adopted in the simulation, and the simulation results show that the torque ripple is obviously reduced.
