Abstract: The use of wire cut electrical discharge machining to process the core of electric vehicle drive motor has the advantages of less performance impact, and is not limited by the design shape of the motor core. It has greater advantages for the processing and manufacturing of the core of electric vehicle drive motor at the research and development stage. Through the process research on improving the wire cutting accuracy of the electric vehicle drive motor core, the wire cutting accuracy was improved by sample stacking, positioning, process technology and so on, meeting the design and processing requirements of the electric vehicle drive motor core, and laying a foundation for the subsequent whole
production of the drive motor.

Key words: wire cutting, accuracy, motor core
