100% Yield with lamination punching for electromagnetic chokes
03/01/2010 5:15 AM
I have seen many using U-T core laminations which have about 72% yield during punching. This results in more utilization of steel and also results in higher carbon foot print as a conseqeunce. Here is some sugegstion for improving punching yield. Hope it benefits someone and hope teh world as whole has smaller carbon emmissions.
ADVANTAGES OF J-I OR L-U DESIGN
Lesser steel consumption and smaller carbon foot print.
Smaller window has smaller average perimeter and hence lesser wire length, lesser wire resistance and lower wire losses.
Smaller window and hence suitable for copper wire too.
Simpler stamping pattern.
Simpler assembly effort on shop.
Can have near cubic dimension. Current design is always 6a x 4a. But with new design it will be 6a wide x any height (=x + 2a).
Winding window = can be any size (=x) x a.
Hence bigger winding window can also mean higher turns, lesser steel and lower costs.
Near cubic shape results in optimal combination for least overall losses = wire loss + steel loss.
