Permanent Magnet Motor Stator Core  

PROGRESSIVE PUNCHING Produced in the progressive punching way is very suitable for small size but large volume generator and motor lamination, which can produce the complete stator & rotor cores with high quantities in a short time. The progressive punching method need possess high-performance and high-speed punches and high-quality molds. Dies take a long time to build and cost higher, but progressive punching is still the optimal solution for large volume motors, the products produced in this way have a very good consistency. OPERATION Cut the silicon steel roll into the required width, and then directly send it to the high-speed press, which can stamp more than one hundred times per minute. Different from other stamping methods, the inside of the tool is complicated, and there are many cutters inside the tool, which respectively complete different steps.  The tool can cut out several rivets on each lamination, these rive…
