Description
The MaalonDrive® HighAcc 10mm - type 2 micro positioning system combines a particularly high angular resolution, simple control as well as an output shaft designed especially for the application all in one system. The robust operating behaviour of this micro positioning system is achieved by the stepper motor with 20 steps per rotation, thereby allowing the unit to easily be operated in an open loop control. At the heart of this micro positioning system is a high-reduction, zero-backlash MaalonDrive® with a reduction ratio of 500:1.
