RasuunDrive® HighVac 10mm – Type 4
The RasuunDrive® HighVac 10mm – type 4 is a micro positioning system suitable for use in high-vacuum environments with a travel range of 40 mm.
The system is driven by a stepper motor with 20 steps per rotation; this is directly connected to a low-backlash CoograDrive® gear with a reduction ratio of 40:1.
Connected to this is a spring-loaded, zero-backlash spindle nut system with a pitch of 0.4 mm.
The linear movement is supported with a preloaded ball guide.
An encoder with ten steps per rotation is integrated here for monitoring the function of the stepper motor.
The connection adapter for attaching the micro linear actuator system is a centring collar with a diameter of 6 g6; the load is coupled via an M3x3.5 thread.
Benefits
1) Vacuum suitable lubrication
2) Easy controllability
3) Integrated limit switches
4) Zero backlash at optimised fit between speed and resolution
5) Wide travel range
