RasuunDrive® BallScrew 13mm – Type 1
With the RasuunDrive® BallScrew 13mm – type 1 micro positioning system, a very compact design is achieved through the parallel arrangement of linear roller table and gear-spindle motor.
The travel range of this system is 10 mm; it is driven by an EC motor combined with an encoder that delivers 100 pulses per rotation.
At its heart is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 that is directly connected to the motor and drives a ball screw with a pitch of 1 mm.
The end positions are monitored by two inductive limit sensors with a switching accuracy of 5µm.
Benefits
1) Compact build up
2) Easy controllability
3) Integrated limit switches
4) Zero backlash at optimised fit between speed and resolution
5) Ball screw
