This paper carries out a comparison of motor loss between PMSMs driven by SiC inverter and Si inverter. Motor loss is firstly modeled. Then, a 2-D FEM analysis is conducted to compare the loss value and iron loss distribution caused by different input current waveforms provided by SiC inverter and Si inverter respectively. In order to validate the simulation result, an experiment platform is established and the comparison based on the test data is carried out with the method of 3-D efficiency map. The result exhibits that under whole operating conditions, the motor driven by SiC inverter shows an obviously lower loss than the one driven by Si inverter. Therefore, the superiority of SiC inverter on motor loss reduction is proved.
