Optimal Current Sensor Position for Switched Reluctance Motor Drives in View of Fault Detection

This paper focuses on the selection of current sensors and the two-current separation during the commutation region for Switched Reluctance Machines (SRMs) taking into account possible faults. In order to reduce the number of the used current sensors, the proposed current sensor location is presented in consideration of the phase current measurement and fault detection. A 1.5 kW 8/6 SRM is considered; both simulation and experimental results show the effectiveness of the proposed approach under the healthy and faulty conditions.
