Abstract: Permanent magnet synchronous motor (PMSM) is more and more widely used in new energy vehicles. Temperature rise is the key factor that affects the performance of the whole vehicle. In view of the existing problems of traditional temperature rise detection method, this paper proposed a method of motor temperature rise detection based on recursive least square method, and proved its feasibility through practical application. It provided a reference for online temperature rise identification of PMSM.
Key words: new energy vehicles; motor temperature rise; temperature rise identification
