Torque Analysis of Switched Reluctance Motor Under Different Loading Conditions

This paper introduces torque analysis of a 4-phase, 8/6 poles, 550W, switched Reluctance motor. In this regard, the influence of varying loads on torque performance is introduced. For the modeling and analysis of this motor's torque, RMXprt (an analytical software) was used in conjunction with Maxwell2D (a finite element method). Because the rotor and stator pole are salient, singly excited, and have nonlinear magnetic characteristics, which creates torque ripple in the motor and complicates analytical procedures. Motor results obtained, such as estimated starting torque, output torque versus speed, torque versus angle versus current, flux linkage versus current versus angle, and torque versus time, were determined by RMXprt and Maxweel2D software. In addition, the simulation results demonstrate that the torque ripple and torque values are greater as the load increases and lower when the load decreases. Finally, the finite element analysis results of torque ripple and torque were compared with the results of the Matlab/Simulink with good agreement.
