In this paper Modelling, position detection and torque ripple analysis of switched reluctance motor(SRM) is investigated under variable loads. SRM is gaining popularity over conventional induction motors with its simple structure, high reliability and high speed operations. Nonlinear mathematical model of a 8/6 SRM is developed in this paper. Operation of asymmetrical converter fed to SRM is also elucidated. Proposed drive is controlled by a PI controller, the need of rotor position in flux estimation is also presented in this paper. The proposed drive is simulated in MATLAB Simulink under variable load conditions. In simulation effect of load on source current, torque, torque error, speed, and speed error is analysed.
