Analysis and Research of Short-Circuit Fault for SRD Based on Maxwell and Simplorer
Abstract:
Switched reluctance motor (SRM) has the characteristic of fault tolerance inherently. Short-circuit in motors windings and the power converter are ones of the most common faults. Based on finite element analysis software Maxwell and circuit analysis software Simplorer, this paper takes an in-depth look at the principle of short-circuit fault, and two cases are simulated, one where a few turns are shorted, and one where a complete pole is shorted, and analysis the effect of main faults on SRD performances based on asymmetric half-bridge power converter, respectively from the view of magnetic circuit and field circuit. Results of simulation show that these failures have exert some negative effects on parameters of current and torque of the entire system.
