Three phase squirrel cage induction motors are widely used in industries and hence in this paper we have aimed to increase a motor’s efficiency by augmenting its cooling process. The motor chosen was of 3 HP rating. Motor structure was altered to improve its efficiency and its performance characteristics were analysed to compare with the conventional motor design. A dynamic model was constructed in Matlab Simulink to observe the changes in speed and phase currents on varying load. After successful dynamic modelling, the motor is simulated using Motor Solver and various performance parameters are observed and monitored. This is followed by improving the efficiency by using Aluminium as material for the stator housing and rotor bar and end ring. Silicon steel is used for stator back iron. High cost of Aluminium used to design the stator casing is compensated by the nullification of high maintenance and operational costs
