CAD and FE analysis of Three Phase Induction Motor

Abstract

In this paper, a comprehensive computer-aided design (CAD) procedure for three phase induction motor is presented. The basic output equations are derived and used for the design algorithm. The developed CAD program gives the design data and the calculated performances of the motor. The design variables such as air gap flux density, slot electric loading, winding factor, stator current density, slot space factor, flux density in the stator back iron, etc., are assumed. Three different motors rating are designed using the developed program, and then finite-element analyses are carried out to validate the designs.
