Description

The RasuunDrive® HighTemp 8mm - type 1 micro linear actuator system is a system with extremely short design that is made possible thanks to a parallel arrangement of linear roller table and gear-spindle motor. As a result, a travel range of 10 mm can be realised with a minimal axial length of 45 mm. The system is driven by a stepper motor with 20 steps per rotation in an open loop control. At the core of the actuator is a zero-backlash MaalonDrive® gear with a reduction ratio of 160:1 that is directly connected to the motor and drives a ball screw with a pitch of 1 mm. Two inductive limit sensors monitor the end positions.
