Design and analysis of squirrel cage induction motor in short pitch and full pitch winding configurations using FEA

Squirrel cage induction motors are very popular in industrial and manufacturing process because of its reliability, low cost and rugged construction. In this paper, three phase, 1.1 kW, 500 rpm Squirrel Cage Induction Motor is designed for 12 pole configuration. The performance of the motor due to full pitch and short pitch winding configurations are analysed and the results obtained are compared. Finite element method is used for the analysis and verification. In addition to that, the harmonics of winding current of the motor is compared for both configurations. The analysis is performed using ANSYS MAXWELL software which is a powerful tool to analyse the performance of machines.
