This paper presents an optimization strategy to get the optimal cross-section of induction motor with maximum induced torque. This can be obtained by using mathematical model equations, which are of main machine design parameters. The optimization strategy has been applied to reach the optimal air gap flux density, optimal inner stator diameter, optimal number of poles, stator slots and rotor bars. The optimization strategy comprises several steps. These steps are repeated using different magnetic materials types in the core and teeth of both stator and rotor. Also, the effect of variation of machine stack length and number of phases on optimized values has been studied. The optimization calculation is performed using MATLAB software. This Study leads to minimize the production costs of induction machines for the same machine outer diameter.
