Motorized Linear Drive for MD40 Feedthrough
Product code: DRVMDMOTL-XXXX
The DRVMDMOTL is a stepper motor-driven one axis linear 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. The linear axis is driven by a Nanotec ST2018L0804 2-phase stepper motor.
The sturdy linear unit ensures unchanging alignment of all components and consistent positioning.
MD40 linear drives can be equipped with the DRVMDMOTL option and configured with either continous rotation of the shaft or as a linear only drive.
Please note that for bakeout the drive must be removed.
Order code: DRVMDMOTL-XXXX
- XXXX = Length of the hole drive (Linear travel of MD40 + 226mm). If you have a MD40-0200-0030, you need a DRVMDMOTL-0426 (200mm+226mm)
