Magnetic Modeling, Prototyping, and Comparative Study of a Quintuple-Set Switched Reluctance Motor

This paper proposes the electromagnetic modeling, prototype realization, and test validation of a new quintuple-set switched reluctance motor (QSSRM) for high torque/ripples and high torque/volume applications. The proposed motor consists of five stator/rotor sets. Each set includes a collection of 4/4 stator/rotor poles, which can operate independently. In this machine, the two sets are energized to produce high torque and also decrease the torque ripple in comparison with the conventional switched reluctance machine (SRM). Five sets have robust interactions between each other in order to produce high torque for the motor. Furthermore, this QSSRM has some other advantages, such as isolated phases, better cooling, high-speed operation, and so on. The proposed QSSRM configuration is based on an optimum-design formula. First, the geometrical design parameters are presented. Then, an electromagnetic model of the machine has been simulated using 3-D finite-element analysis. A prototype motor has been manufactured and tested in the laboratory. The new structure has been compared with a traditional SRM. The experimental results and comparative study validate the proposed design operation. The test results indicate that the proposed structure offers an enhanced performance in terms of higher torque density.
