摘要：
In order to solve the steady and transient temperature field of permanent magnet synchronous fast and accurately, a surface permanent magnet synchronous motor(SPMSM) was taken as an example, the model of whole domain heat network was established and the temperature field was solved by lumped-parameter thermal-network(LPTN) according to the principle of lumped parameter thermal network method based on analyzing the advantages and disadvantages of the thermal analysis methods for electric machines and reasonable equivalence the motor structural parts. The accuracy of the LPTN was verified by using the experimental test results and the calculation results of finite volume element method, and then the starting and steady temperature rise time and space distribution characteristic of different structure parts of the SPMSM were analyzed respectively in detail. The distribution law of steady and transient temperature rise for the electric machine is revealed, by which the references for the state monitoring, performance analysis and optimization of electric machine were provided. © 2020, Harbin University of Science and Technology Publication.
