Rotor lamination for motors and generators
COMPOUND PUNCHING
Compound punching outputs a complete motor lamination in one action, some more complicated PM motor rotor laminations may need to be stamped twice. Undoubtedly, laminations produced by compound punching have good flatness and concentricity, and the production rate is also very fast. It’s quite a good choice for medium-to-large volume production, although the cost of the tool is not cheap, when the cost is allocated to each motor lamination, the compound punching solution seems to be both efficient and economical.
COMPOUND PUNCHING MOTOR LAMINATION
The production capacity of compound punching depends on the performance of the punching machine and the size of the base (for installing the mold). Compared with rotary notching, the cost of compound die is times higher.
Compound punching is useful for the medium size motor laminations, therefore, the size of the die is relatively large, and the entire die is fixed between the pi…
