Analyzation of Temperature Rise in Induction Motor for Electric Vehicles

Thermal analysis contributes to achieving the major improvements in the design which affects the overall performance of the machine. It has been found that the induction motor fails frequently due to the overheating of various motor parts involved in operation under loaded conditions in electric vehicles. A computational analysis is required to predict the rise of temperature in all the parts of the motor. This paper investigates thermal analysis of 15 kW totally enclosed fan cooled (TEFC) induction motor using the finite element method (FEM). Computation of the temperature rise in various parts of the motors under rated load is performed by considering the Joule’s losses. The results give the temperature distribution in various parts of the motor. The simulated and experimental results are validating the proposed methodology.
