Abstract
Induction motors (IMs) with varying torque-speed characteristics are widely employed in various industrial applications. However, designing an efficient induction motor requires some of the main parameters of the motor (torque, speed, and efficacy) to be investigated and optimized. Furthermore, due to the significant influence of the rotor slot configurations on the electromagnetic torque-speed envelope, a design optimization procedure is required to optimize the induction motor's dynamic characteristics. In this paper, the impact of rotor slots’ geometrical modifications on the behavior of 3-phase, four poles, 36 slots, and double-layer squirrel cage IM are presented and considered as examples of optimization. Moreover, the effect of the air gap dimension and bore diameter of the stator and rotor parts are investigated. The predicted results demonstrate that the constructed geometry of the rotor slots has an observable effect on the performance of an (IM).
