Electrical Steel Stampings For Motors And Generators 

PROGRESSIVE PUNCHING Small size but large volume generator and motor lamination is very suitable to be produced in the progressive punching way, which can produce high quantities in a short period of time, even the complete stator & rotor cores. The progressive punching method mainly relies on high-performance and high-speed punches and high-quality molds. Though dies take a long time to build and cost higher, 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. There is even a special stacking area inside the tool. The to…
