集中巻IPMモータの鉄損及び磁石渦電流損解析 Iron Loss and Magnet Eddy Current Loss Analysis of IPM Motors with Concentrated Windings
In this paper, we investigate losses of interior permanent magnet motors with concentrated windings using the 3-D finite element method considering carrier harmonics of PWM inverters. The calculated results are compared with the measurement to verify the validity of the calculation. The motor with the distributed windings is also calculated to clarify the difference of the main loss factors. The measured and calculated results agree well. It is clarified that the losses generated at the rotor core and magnets especially increase, whereas the harmonic iron losses generated at the stator decrease, in the case of the motor with concentrated windings.
