초록
This paper deals with the analytical method to calculate the high temperature demagnetization characteristics of a high-speed machine with diametrically magnetized permanent magnet rotor. The equivalent magnetic circuit model is used to analyze the magnet operating point on high temperature condition. Agreements have been obtained between the results of the analytical model and finite-element analysis on prototype high-speed motors.
