RasuunDrive® BallScrew 10mm – Type 1
The RasuunDrive® BallScrew 10mm – type 1 combines a stepper motor, a MaalonDrive® gear and a ball screw. Connected to the stepper motor with 20 steps per rotation is an encoder with a resolution of 10 pulses per rotation. At its heart a zero-backlash MaalonDrive® gear can be found with a reduction ratio of 160:1. Directly integrated in the bearing of the gear output shaft is the ball screw with a pitch of 1 mm.
Benefits
1) Flexible integration
2) Robust control without feedback system
3) High load capacity of output bearing
4) Zero backlash at optimised fit between speed and resolution
5) Ball screw
