With the expansion of the electrical vehicle automobile industry, the importance of operating traction motors at optimal operating points has increased. However, the characteristics of internal resistances and permanent magnets vary with temperature, requiring control strategies based on the loss prediction to estimate thermal behavior and efficiency . Several methods have been proposed to estimate iron loss of motors, such as Steinmetz method based on Fast Fourier Transform, loss separation method based on Fast Fourier Transform and the method considering the influence of DC bias fields and hysteresis minor loops. DC-biased magnetic, etc.
In this paper, a motor-inverter system was modeled to generate three-phase current harmonics and compared the result between Steinmetz method based on Fast Fourier transform with and without consideration the phase of magnetic flux density obtained from Finite element analysis. The analysis was performed on 8 pole, 48 slots IPMSM model. The simulation result showed that when harmonic current is applied, iron loss increased by about 3% in the sinusoidal area when the phase of the magnetic flux density was considered, whereas it decreased by 2% in the harmonic area under rated torque compared to the case without phase consideration.
