Summary:The Electrical Vehicle industry has developed rapidly in recent years, and the demand for new energy-driven motor systems has also increased. Permanent Magnet Synchronous Machine (PMSM) are high performance drive motors. In this paper, a new type of GO silicon steel material assembled stator core is proposed, compared with conventional Non Grain-Oriented (NGO) silicon steel stator, and the magnetic properties of the motor are analyzed. The method of assembling the stator core is given, in which the GO silicon steel sheets are stacked as the teeth of the stator core. GO silicon steel has low iron loss and large saturation magnetic density, which is more conducive to improving motor efficiency. The teeth of the stator core tend to have higher magnetic density and are more prone to sustain a higher iron loss. This research ensures the reliability of the test results through simulation analysis and physical test verification.
