“…The losses in the driving electric motors mainly consist of mechanical, copper, and core losses (iron losses). Recently, in order to reduce core losses of the motors, the motors based on core with amorphous magnetic materials (AMM) [1][2][3][4][5][6][7][8][9][10][11][12] and nanocrystalline magnetic materials (NMM) [13][14][15] have been developed and examined. NMM and AMM exhibit lower iron loss 16) than nonoriented (NO) silicon steel sheets.…”

In this paper, we focus on an evaluation of core losses in permanent magnet synchronous motors (PMSMs) made of nanocrystalline magnetic materials under inverter and sinusoidal excitations. To discuss the core loss properties of a nanocrystalline motor, comparison with PMSMs made of amorphous magnetic materials and non-oriented (NO) silicon steel sheets is also performed. Under sinusoidal excitation, the core losses of the nanocrystalline motor were about 0.7 and 0.5 times smaller than those of the amorphous and NO motors, respectively. In particular, we found that the nanocrystalline motor reduced the core loss on the basis of time harmonic components in comparison with not only the NO motor but also the amorphous motor. On the basis of our results, the nanocrystalline motor is expected to be suitable for use in high-speed and high-frequency regions.

This paper presents the numerical comparison in ANSYS Maxwell between nanocrystalline, Vitroperm 500F, and ferrite, 3C90, cores to be used in power electronic converters (PECs) transformers. The converter topology used is the doubled switch Forward, due to its characteristics and its power range (<500W). The transformer model development, the characterization and the BH measure curves from the material, as well as its validation and the excitation type implemented in the numerical model are described in the methodology. The exposed results show an improvement in comparasion with the ferrite, in addition to a better flexibility in the magnetic design methodology, given by the nanocrystalline magnetic characteristics.
