Abstract |
This paper proposes a deformed zero-sequence flux model of open-end winding (OEW) Interior Permanent Magnet Synchronous Motor (IPMSM), which takes into account non-linearity and structural features of IPMSM. The flux and phase voltage of the IPMSM are investigated using finite element analysis (FEA). This analysis confirmed the existence of the zero sequence voltage (ZSV) that causes the zero sequence current (ZSC) when utilizing an OEW inverter. Additionally, the presence of coupled components between the zero-sequence and DQ axes due to the winding structure and core saturation is identified. The proposed model effectively expresses the properties of zero-sequence components in IPMSM. |
