Compound introduced the motor stator laminations and rotor discs a stamping forming of blanking die, stator laminations, rotor discs by ladder rushed inside and outside the stator, rotor, stator groove inside and outside the circle round the separation of the mold in the key rotor intensive was both a blade and a stripper plate, all adopt the die steel manufacturing. The whole cutting process, a process with only could complete, greatly increased production efficiency, saves the manpower, reduces the production cost, improved the precision of the stator laminations.
