Linear Technology

Linear motor axis drives (standard - X,Y,U,V axis)

Advantages of linear motor drives

  • eliminates ball screw drives
  • no back lash or lost motion
  • best part geometry & finish with reduced skim passes
  • fewer wire breaks
  • increase cutting speed
  • no maintenance

Don’t get ball screwed

Over time ball screws will wear, creating scrapped parts; but since linear motor drives eliminate the need for ball screws, they have also eliminated the possibility of scrap parts

How linear motor drives work

  • Linear drives contain the same components as a servo motor (magnets & copper coils).
  • A linear motor is an uncoiled servo motor.
  • As amperage enters the coils, it creates force that is repelled against the magnets.
  • The motor is also the driving force thus eliminating the need for a ball screw.

Linear motors = No Ball Screws

  • worn ball screws can create scrapped parts & downtime
  • ball screw replacement parts can cost as much as €5.000
  • with linear motor drives you will never worry about this
