Abstract Aiming at the compact structure and high power density of surface-mounted and interior perma
nent magnet synchronous motor(SIPMSM), accurate calculation of 3-D full-domain temperature distribu-
tion for SIPMSM is very important. The coupling analysis of electromagnetic field and temperature field
ras adapted to calculate 3-D temperature field distribution of SPMSM. Finite element modes of electro-
magnetic field and temperature field were established to analyze the influences of load and permanent
magnet demagnetization on 3-D full-domain temperature field of SIPMSM at synchronous speed, and the
influences of various speed on 3-D full-domain temperature field of SIPMSM with rated load were also an-
lyzed. The reasonability of prototype model and accuracy of results were verified by comparison of simula
tion and test
