3D thermal stress analysis of the rotor of an induction motor

This paper analyzes the temperature distribution of an induction motor in steady state using a hybrid thermal network method-finite element method (TNM-FEM). 3 dimensional FEM has been used to analyze the thermal stresses on the rotor of an induction motor. The mechanical deformations and thermal st...

Description
Summary:This paper analyzes the temperature distribution of an induction motor in steady state using a hybrid thermal network method-finite element method (TNM-FEM). 3 dimensional FEM has been used to analyze the thermal stresses on the rotor of an induction motor. The mechanical deformations and thermal stress distributions are obtained. The numerical analyzes of the thermal field are verified by experimental results.
