stator lamination for hydro power

COMPOUND PUNCHING 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. 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 MOTOR LAMINATION 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 effic…
