N2 - This paper describes an impact of a flux weakening current to an iron loss which includes a modulation index effect and PWM carrier effect. 1.5kW IPMSM was selected as a test machine, the measured iron loss are analyzed and compared with the simulation results which are obtained by a coupled simulation between FEA and circuit simulator. Interesting results are shown in this paper such that the iron loss is not decreased linearly with increasing the flux weakening current and the modulation index much effect to the iron loss because of the iron loss into the core by PWM effect. This paper can contribute to make the high efficiency machine and also can achieve a high efficiency drive.
