Study on fault tolerant switched reluctance machines

The paper´s goal is to compare a usual switched reluctance machine and a fault tolerant variant of it. By coupled Flux 2D and Simulink transient simulations the behaviour of the fault tolerant drive system under different winding fault conditions were studied. It was proved that using the proposed machine structure and converter topology same torque capability of the machine in faulty states as in healthy conditions can be assured. A short discussion on fault-tolerant converters is included in the paper, too.
