Motorized Linear and Rotary Drive for MD16 Feedthrough

Product code: DRVMDMOTLR16-XXXX

The DRVMDMOTLR16 is a stepper motor-driven linear and rotary actuator. It's high precision motorized spindle drive is coupled to the outer magnet and controls linear motion. With a 2mm pitched spindle, a resolution of 0.01mm is possible. Alternatively, a 1mm pitched spindle provides even higher resolution.

Rotation of the shaft is activated via gear wheels that transfer motion from a second stepper motor.
The sturdy linear unit ensures unchanging alignment of all components and consistent positioning.

A Nanotec ST2018L0804 2-phase stepper motor drives the linear axis and a second stepper motor with gearbox drives the rotary axis.

MD16 linear/rotary feedthroughs can be equipped with this option.
For retrofitment to your linear/rotary feedthrough, please contact us.

Please note that for bakeout the drive must be removed.
