Abstract
This paper presented the loss characteristics of interior permanent-magnet machines (IPMSM) for a fuel-cell electric vehicle. In order to study the loss characteristics of the machine, one prototype machine having 100 [kW] was designed. In the analysis, to consider the harmonic magnetic field and the rotational variation of flux vectors in the core of the machine effectively, we proposed a new harmonic iron-loss calculation method based on adaptive loss coefficients. To verify the performance of the proposed method, we calculated a no-load iron loss in an IPMSM with conventional methods. Then, the estimated iron losses were compared with the experimental data. It was clarified that the proposed method is more effective than conventional methods at high-speed operation. Based on this proposed method, we investigated the losses of the machine considering operating points according to its speed. From the results, it was shown that the main loss component and the location of iron-loss distribution change depending on operating condition.
