High torque to weight ratio and cost estimation of cage induction motor with finite element method for hybrid vehicle

Abstract

Induction motor is the most popular load in the transportation systems like Hybrid vehicle, Traction and Propeller. Now-a-days most of the researches are done on hybrid vehicle. It is very important to study about the cost effective, efficiency and quality on induction motor performance. For easy transportation purpose the weight of the motor is low and similarly for the performance of the motor the torque should be high. One of the most important problems is torque and weight ratio in electric hybrid vehicle. This project evaluates the good design with optimization, torque and weight ratio of four configuration methods and cost estimation of each configuration using finite element method (FEM) of a Three — Phase Induction Motor. Here we have changed the rotor bar and end ring materials using Aluminum and Copper with different configurations. By using these configurations we have shown the losses, efficiency, weight and impact on material cost of an induction machine.
