The switched reluctance motor (SRM) has a simple rotor construction with no windings. simple concentrated windings on the stator. Thus, it is expected to be a lower cost machine to manufacture than the squirrel cage induction motor.instantaneous and average torque of the SRM. analysis of flux linkages and inductances for varying positions of the rotor and at different values of the stator excitation currents. The finite element method (FEM) is generally considered to be the preferred approach to determine the flux linkage inside the motor. The locked rotor torque and instantaneous current and torque waveforms for the SRM have been calculated using two-dimensional FEM and the results are shown in the paper. The effects of switching the stator winding excitation ON and OFF at different positions of the rotor are included. Experimental results for a 10 hp Gulton switched reluctance motor are shown. In addition, the paper includes a comparison of the SRM with a Century Electric induction motor of the same rating. It also hasThe main object of this paper is to predict the An understanding of the SRM requires a detailed 1.0 Object The object of this paper is to predict the average and the instantaneous torque of the switched reluctance motor (SRM) fed from a GTO controller with pulsed voltage excitation and to compare this torque with the torque produced by the induction motor (IM) of the same rating. study the effect of voltage and speed variations on the performance of the SRM.An understanding of the SRM requires a detailed analysis of the flux distribution, flux linkages and inductances for varying positions of the rotor at different values of stator excitation currents. The reluctance variation of the SRM has an important role in the performance of this motor. However, the large variation in the air gap of the SRM and operation of the motor under saturated conditions makes the magnetic field analysis very difficult through conventional analytical methods. Thus, the FEM method is the preferred approach for SRM analysis.From this analysis, the effects of practical control variables, such as the excitation of each phase relative to the position of the rotor, on design objectives including optimum torque and efficiency have been determined.Experimental results are presented for a 10 hp SRM with its inverter controller. In addition, a comparison of power output per unit volume for the SRM and the induction motor (IM) is included.A secondary objective is to 2.0 Description of the Switched Reluctance &tor Drive In recent years there has been a growing interest in the design, performance, control and improvement of switched reluctance motor drives (SRM). The SRM has the advantages of a simple construction, concentrated windings on the stator and no windings on the rotor itself. The SRM is similar to a variable reluctance stepping motor (VRSM) except that the VRSM is generally designed as a low power positioning device which runs in synchronism with a pulsed supply, whereas the SRM is designed to provide an efficient and sm...
