Abstract: This paper presents the designing of the main dimensions and the selection of the magnetic and electric loading for different rating of squirrel cage induction motors to reduce the overall losses and to improve the power factor. A software development strategy for the design of main dimensions and the effects of various factors are studies to select the best parameters for the particular ratings of the machines. The redesign time can be reduced with the help of this software during the course of learning and manufacturing of the inductions motors. The idea of designing the main dimensions of three phase squirrel cage induction motor by MAT LAB GUI is simple fast and friendly nature.

Keywords: Three phase squirrel cage induction motor, MAT LAB- GUI.
