Modelling of Switched Reluctance Motor Using Finite Element Analysis

Abstract

Induction Motors (IM) are widely used motors in industries due to its simple construction, rugged nature and low costs. But the drawbacks of these motors are low starting torque and large inrush currents. They operate under poor lagging power factors due to which I2 R losses in the system would increase causing reduced efficiency of the system. At present Switched reluctance motor is finding enormous application in various fields due to itshigh performance. A switched reluctance motor is a type of stepper motor which runs by reluctance torque. In this type of motor power is delivered to stator windings instead of rotor and no permanent magnets required for rotor.It combines the desirable features of induction motors, permanent magnet brushless dc motors. There are numerous software’s available for the modelling of electrical machines such MATLAB, Comsol, Motor solve, Ansys Maxwell etc. ANSYS RMxprt is efficient and low cost tool suitable for design of various electrical machines. This paper, the authors presents themodelling, analysis of 8/6 switched reluctance motor using ANSYS RMxprtr and the Electromagnetic calculation along with 2-D and 3-D geometry.
