Experiment and Modeling on Heat Power of Permanent-Magnet Synchronous Motor

This paper presents a novel methodology for measuring the heat power of a permanent-magnet synchronous motor based on the thermal equivalence principle. Firstly, a set of experimental apparatus has been designed and implemented. Then a series of experiments has been conducted for obtaining a set of heat power values of the motor working at different speed and torque. Based on the experimental data, the algorithms of fitting regression and SVM regression have been respectively employed to build the heat power models. The analysis and comparison of the two models shows that they both have a good accuracy in predicting the motor heat power in testing range.
