Radial Force Control in Switched Reluctance Motors by Using Strain Gauges

Abstract

　Switched reluctance motors (SRMs) are reliable and have a low manufacturing cost. However, due to the high vibration and acoustic noise of SRMs, SRMs are not being widely used in industry and electric vehicles. This paper introduces a novel approach for controlling the radial force in switched reluctance motors to reduce acoustic noise. The method relies on strain gauges attached to the stator teeth to measure the radial force. Simulation results from MATLAB and finite element analysis demonstrate that the proposed control method accurately converges the generated radial force to the reference value.
