Linear motors

Characteristics of the ML 1 linear motors
  • direct drive with uniform, linear force
  • particularly suitable for positioning and feed movements of high dynamics and high accuracy, e. g. in
    • handling and assembly systems
    • packaging machinery
    • electronics production machinery
  • compact size
  • low weight
  • ironcore versions with low attractive forces or ironless without attractive forces and cogging
  • high acceleration (up to 6 kN peak force)
  • high speed, up to 18 m/s
  • high dynamics and accuracy in combination with high-resolution optical encoders
  • motor length as required since secondary part (magnetic plate) consisting of elements
  • also available as complete linear direct drive consisting of coil unit, magnetic plate, incremental encoder, and guides
