Abstract

Permanent magnet synchronous motors (PMSMs) are widely used as an automotive motor, and there has been a demand for their further technological advance. A harmonic current control method has been used as a controllable approach for realizing its low vibration of PMSMs. In addition, a dual inverter system has attracted attention as an automotive motor system considering its fault tolerant function. In this study, an open-winding structure PMSM driven by dual three-phase inverters, which share a DC bus source, is used for the proposed third harmonic current control. By using third harmonic current control, it is possible to reduce both the sixth order torque ripple component and the second order radial force. The performance of the third harmonic current control of the open-winding PMSM is verified through FEA and experimental results.
