An analytical evaluation method of the temperature dependence of resistive losses in electric motors

Abstract

In this work, the temperature dependence of motor resistive losses has been analytically evaluated by using a quantum mechanical approximation. It is well known that the Bloch-Gruneisen approximation is a fundamental quantum theory to the study of the resistivity of the conductor with the change of temperature by using analytical formulation. By using the proposed method, the motor resistive losses can be controlled with respect to the temperature changes. The accuracy of the proposed algorithm has been tested by comparison with different theoretical approaches. It is demonstrated that the new analytical method for the motor resistive losses controlled with the change of temperature will be used for improving motor power and mechanical systems.
