Abstract :
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.
