This paper proposes a new method for behavioral modeling of a permanent magnet synchronous motor (PMSM) fed by a PWM inverter considering the iron losses due to carrier harmonics. In the proposed method, an inductance is connected in series with an iron loss resistance in the equivalent circuit of the PMSM to suppress the harmonic current due to carrier harmonics. The effectiveness of the proposed method is investigated by comparing the numerical results of iron losses of the PMSM obtained using a finite‐element method and the newly derived equivalent circuit.

考虑载波谐波引起的铁损的PWM逆变器供电的永磁同步电动机的行为建模

本文提出了一种考虑由载波谐波引起的铁损的PWM逆变器馈电的永磁同步电动机（PMSM）行为建模的新方法。在提出的方法中，在PMSM的等效电路中将电感与铁损电阻串联连接，以抑制由于载波谐波引起的谐波电流。通过比较使用有限元法和新推导的等效电路获得的PMSM铁损的数值结果，研究了该方法的有效性。
