Motor Structure

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

Motor Design

A 1-phase induction motor usually has a complicated windings design which compares to polyphase induction motor. In addition, a large capacitor start is required to operate the motor. It is an expensive way to operate the motor if it compare to polyphase induction motor. So, a new innovation method is required to make the motor more simple and cheaper. This research is purposed to study a new winding design for a single-phase capacitor motor. Winding design of the motor was conducted to a simple winding design like a 4-phase induction motor that has four identical windings. The comparator motor that use in this study was a Three-phase induction motor with data 1400 RPM, 1.5 HP, 50Hz, 380/220V, Y/Δ, 2.74/4.7A, 4 poles, that had the same current rating which the proposed method. The result showed that the motor design on this proposed method could be operated at 88.18 % power rating with power factor close to unity.
