Abstract

This work investigates a method to reduce the carrier harmonic current and the carrier harmonic losses of a permanent-magnet synchronous motor (PMSM) with dual three-phase windings. The motor input impedance of the carrier harmonics is increased to reduce the carrier harmonic current by reinforcing the carrier harmonic gap flux density of the dual three-phase windings. Our study is carried out based on a theoretical approach by calculating the gap flux density, including the space, time, and carrier harmonics. The result of our theoretical approach is confirmed by finite element analysis (FEA) based on a 12-slot, 10-pole phase-shift winding dual three-phase PMSM. The measured result of our manufactured motor also reveals that the target harmonic current was reduced by applying our proposed technique.
