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 tool can cut out several rivets on each lamination. These rivets are compressed in the stacking area and each lamination is locked to each other.

 

APPLICATION & COST

Electrical lamination of mass-produced motors is very suitable to be produced in the progressive punching way, which can produce high quantities of Motor Laminations or motor cores in a short period of time. Though dies take a long time to build and cost higher, the products produced in this way have a very good consistency.
