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
