Comparison of Electro-magnet Charateristics of Interior Permanent-Magnet Synchronous Motor according to the Number of Phases

In this paper, the author researches the electromagnetic performances of interior permanent magnet synchronous motor (IPMSM) considering the number of phases. The analysis is carried out by the comparison of three and six-phase models in terms of harmonic components. The harmonics are analyzed by observing torque ripple and iron loss. Distributed winding is applied to both models. The asymmetrical...
