thermal behavior such as temperature rise is the most important index of an electrical machine, especially in the motor for electrical vehicle. A 7-element thermal circuit model of electrical machine has been proposed in the companion paper of this paper. Each thermal resistant in the proposed model has been derived in detail. In this paper, a prototype machine is introduced to verify the accuracy of the proposed model. The items that may cause the calculation error are analysis. The result shows that, the model presented in the companion paper is suitable to use in machine design with certain accuracy.
