The Research of Manufacturing Technique about Intertwined Stator Core in Automotive Alternator

Intertwined automobile generator stator core is made from twisted Strip steel with teeth. This winding process is different from the method of traditional laminated machining. Intertwined technique is a new method that for the manufacturing of stator cores in automotive alternators. The productive process include such key steps: Leveling of the bar-typed materials, stamping, enwinding, soldering and plastic. This methods has raised the production efficiency and used ratio of the materials, and even make a cost reduction compared with the traditional ways of strap-typed stator core manufacturing. They are able to make a substitution to the imported products by most automotive alternator enterprises as well as complete the blanks of domestic market and have a large extent of social and economic benefits.
