KeevoDrive® HighVac 10mm – Type 6
KeevoDrive® HighVac 10mm – Type 6 is an especially dynamic
micro positioning System, suitable for applications in high vacuum. The positioning System is based on an eccentric with eccentricity of
1000 µm which leads to a travel range of up to 2000 µm. Driven by a stepper
motor with 20 steps per rotation, the actuator can be operated in
an open loop control without difficulty. Furthermore, it is equipped
with a zero-backlash MaalonDrive® gear with a reduction ratio of
160:1.
Benefits
1) Vacuum suitable lubrication
2) Robust control without feedback system
3) High load capacity of output bearing
4) Zero backlash at high adjustment speed
5) Step with in the range of nm
