Estimation of Vibrations in Switched Reluctance Motor Drives

This study discusses a simple algorithm for estimation and reduction of Vibrations in a Switched Reluctance Motor (SRM) using magnetic circuit simulation in MATLAB/SIMULINK Environment. A Non-linear model is developed using magnetic circuit equations, wherein non-linearity is added using a inductance profile with back EMF. Dynamic characteristic of the SRM is simulated and the same is being verified experimentally. In this simulation, both current and voltage control techniques are used to control the SRM. Fast Fourier Transform is used to analyze the electromagnetic torque in Frequency domain, which gives the mechanical and magnetic vibration frequencies and their dB magnitude. The complete simulation and experimental results are presented.
