Electric motor lamination press lines (rotor/stator/segments)

The production of electric motor and generator laminations imposes strict requirements on the press and automation. ANDRITZ Kaiser looks back on decades of experience in the electric motor laminations sector and provides the customer with state-of-the-art solutions.

Precise timing and general performance are required for competitive productivity of high speed stamping systems for laminations. Due to the large amount of cutting operations required, a very rigid machine is needed to absorb the cutting impact without damaging any machine part. Finally, the tolerances of 0,02mm in the tools and the end product call for a very precise slide movement, slide guideance and low frame deformation.

Our well designed and thoroughly tested concept allows customers to manufacture high-quality products with maximum efficiency. ANDRITZ Kaiser production lines for electric motor laminations are characterized by the following features:

  • Highly stable machine with split-design, cast iron frame for good vibration absorption and very low deformation
  • Clearance-free, pre-stressed guiding system for perfectly parallel sliding at every point of movement
  • Customized design of the tool area and the tool clamping system
  • Best-in-class coil handling system with/without zig-zag roll feeder 
  • Fully automatic lamination unloading and stacking device
  • Fully automatic lamination unstacking device in combination with compound die tools
  • Central line control PLC
Every tool chamber is customer-specific
