DESIGN OF 5KW, THREE (3) PHASE SQUIRREL CAGE INDUCTION MOTOR

Abstract

This paper presents the project work whose aim was the design of Skw squirrel cage industrial three-phase induction motors, making use die cast copper rotor cage and premium electrical steel. The project is concern with industrial low voltage three-phase induction motors, 4 pole, 50 Hz, 400 V, in the 5kW power range. This design can be used or improved on, to manufacture squirrel cage industrial 5kw induction motor. This project is also a practical attempt to employ the power of computers to design workable induction motors. By the use of computer, a lot of time can be saved without compromising accuracy. According to the motor specifications intended, design parameters can be altered and results of such alterations would be ready which can be used for comparison without having to manually recomputed over and over again. The project is devoted to selection of main dimensions, the electromagnetic processes that take place in the induction motor and the active resistance and reactance. On the whole, the project is concerned with the analysis, synthesis, computer aided design and practicability of the squirrel cage induction motor.
