The research on electromagnetic and thermal issue of the high power density permanent magnet synchronous motor based on thermal conductivity optimization of the armature end
This paper investigates the relationship between the electromagnetic parameters and the extreme input current in a permanent magnet synchronous motor (PMSM). It is found that the direct-axis inductance, DC resistance, and back-EMF for no load conditions have a large influence on the limit of the extreme input current. Hence, the lower back-EMF and smaller direct-axis inductance can help to improve the max output power of PMSM. Finite element analysis is performed for thermal modelling using the ANSYS Workbench and verified by test experiments.
