Notching machines for single notching of Rotor and Stator laminations

With the new developed notching machines electrical laminations can be produced very efficient and cost effective. Depending on size and Press force of the notching machine laminations from small to large size can be produced with the highest precision.

Innovations of the new notching machine:

O-Frame and pendulum motion

  • Implementation of the machine frame as “O-Frame)
  • The pendulum motion of the slide allows the optimization of the blanking process and the automation.

    Tool change

    • Tool change and setup can be done with best possible accessibility from the back side of the machine

    Precision

    • Highest precision of the pitch of the indexing drive at high speeds

    3 Versions depending on Press force and size of lamination:

    • 50 kN Press Force
      max. blank diameter of 800 mm
    • 100 kN Press Force
      max. blank diameter of 1200 mm
    • 160 (200) kN Press Force
      max. blank diameter of 1500 mm (1800 mm)

    Advantages of the new concept

    • User friendly operation of the machine with simple programming of the motions of main and indexing drive
    • Simple user guided optimization of the blanking process
    • Simple setup of the tool from the back side of the machine
    • Rigid frame in “O”-configuration with symmetric deflection for maximum tool life
    • High Dynamic Servo Drives for maximum production output
    • Dynamic mass compensation for a balanced system without vibrations
    • Low Maintenance Design
    • Simple Concept and Design of the automation
    • For all notching machines a modular automation for minimum necessary space and maximum output is available
    • Siemens control of the newest generation
    • Various additional functions (Intermittent mode, notching in two positions, …)
