Description

The KeevoDrive® HighAcc 10mm - type 4 micro positioning system combines an eccentric input system with flexure hinge kinematics, thereby allowing outstanding accuracy in the linearity of the movements to be realised. The flexure hinge kinematics consists of the elements of the linear guides and, in addition, feature customer-specific fastening structures for connecting the application and the positioning system. The combination of a low-backlash CoograDrive® gear with a reduction ratio of 40:1 with an EC motor with rated voltage of 6V and an integrated encoder with a resolution of 1024 pulses per rotation results in an especially high-performance micro positioning system. An optical linear encoder with a resolution of 0.2 µm is integrated additionally for position control.
