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).

Nowadays, induction machines can be considered as the backbone of various industrial applications due to themany characteristics such as rigidity, simplicity, high reliability, and low maintenance that can be manufactured for a long time.However, poor efficiency and power factor and increased amounts of torque ripple and losses have a significant impact on theperformance and hence its efficiency. Therefore, in order to improve the performance of induction machines, the special designtopology for stator and rotor configurations must be investigated and correctly estimated. In this paper, the analysis of thevariable geometries of the rotating bars of the cage is presented. More specifically, the influence of dimensions and positions aswell as shapes of the rotor rods which have a significant impact on the dynamic performance (developed torque, starting torque,ripple torque, starting current, power factor, harmonics, output power, and efficiency) are investigated. The Finite ElementMethod (FEM) are used to create the optimum designs as well as calculations are used to optimize the shapes of rotor slots inorder to improve starting performance characteristics such as starting current, initial torque, magnetic flux connection understarting conditions, and efficiency. furthermore, the characteristic of the manufacturing material of the rotor are examined andmethods to reduce losses for an induction motor to enhance efficiency are examined. The focus of this paper is on the squirrelcage induction motor (SCIM).

Squirrel cage induction motor (SCIM) plays an important role in industrial applications thanks to its hardness, durability, and ease of design. With all these advantages, research is still being conducted to improve the performance of the induction motor because it suffers from problems such as low power factor as well as ripple torque and low efficiency. The main objective of this paper is to discuss the increasing of the starting torque and decreasing the ripple torque, as well as increasing the efficiency of the squirrel cage induction motor based on specific methodologies carried out on the rotor bar by changing its position in the horizontal and vertical directions, as well as implementing the skewing effect on the rotor bar and analyzing the impact of each of these changes on the performance and efficiency by using the finite element method (FEM).

This paper presents a systematic optimal design algorithm for the shape of the rotor slot to get optimal operating torque and efficiency in a three-phase squirrel cage induction motor (SCIM). The determination of the ideal dimensions of the rotor bar is carried out with a multi-objective genetic algorithm (MOGA). The primary purpose is to enhance induction motors' performance and verify the predicted results with analytical calculations. Maxwell Ansys 2D has implemented the parametrical method for modeling the SCIM, and the result shows an increasing ratio of the starting torque by (22.35%), as well as the efficiency by (6.67%) and a reducing ripple torque by (34.68%).
