KeevoDrive® HighRes 19mm – Type 1
The KeevoDrive® HighRes 19mm – type 1 is a micro positioning system based on an eccentric with eccentricity of 500 µm and travel range of up to 1000 µm.
It can easily be operated in an open loop control, as it is driven by a stepper motor.
At the heart of this high-reduction and reliable micro system is a zero-backlash MaalonDrive® gear with a reduction ratio of 1000:1.
Thanks to the high step number of the motor of 200 steps per rotation and the high-reduction micro gearbox, precise resolution into the nanometre range is possible.
Benefits
1) High reliability
2) Robust control without feedback system
3) High load capacity of output bearing
4) Zero backlash at ultra high resolution
5) Resolution ini the range of nm
