Abstract

This paper describes the improvement in the steady-state performance of squirrel cage induction motor (SCIM) by using capacitor injected in the auxiliary winding of the modified dual stator winding SCIM. A balance capacitance load is connected at the terminals of the auxiliary winding, and by appropriate choice of the capacitor, the overall reactance of the machine is reduced with concomitant increase in output torque, power factor, and efficiency. The analytical prediction of the performance characteristics is validated with MATLAB simulation. From the simulation results, it was observed that the torque of the modelled machine was greatly improved to about 64Nm as against the 23Nm for the normal machine when a capacitor of 500µf was injected. Similarly, the power factor of the machine was equally improved to 0.92 as against 0.78 for the normal machine. The same maximum power factor was realized with 500µf capacitance injection. In addition, the efficiency of the modelled squirrel cage induction motor was increased from 60% to 80%
