Stator lamination segment for generaotrs

COMPOUND PUNCHING

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 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.

COMPOUND PUNCHING MOTOR LAMINATION

The round sheet is stamped into a lamination in an instant, and the entire feeding and output process can be operated by automated system or worker. Its operating speed is much faster than rotary notching speed.

Compound punching is suitable for the medium size motor laminations, therefore, the size of the die is relatively large, and the entire die is fixed between the piston and the base of the press. 

APPLICATION & COST

In the process of motor production, on the one hand, we are strengthening the manufacturing quality control of the motor iron core, and on the other hand, the iron core and the windings are cured into a solid whole through the dipping process.

Compound punching is very suitable with automated feeding and output systems, which can maximize the capacity of the press and greatly improve production efficiency. More than half of our compound punching presses have been matched with automated systems.
