MD40H hollow range
CF40, 2.75" OD flange, 9Nm torque
Hollow MagiDrive series
Terminating with a non-rotating CF flange at their rear, our four largest MagiDrive rotary feedthroughs are available in a hollow configuration. This design allows services to be passed through the drive or, alternatively, an additional MagiDrive to be mounted to the rear. This setup provides a second axis of rotation. However, up to four independent axes of rotation can be provided by combining the MD16, MD35H, MD64H and MD100H MagiDrives. Typically, this stacking capability is used to provide simple solutions to sophisticated manipulation requirements.
Key Features
- Allows services to pass through the centre, i.e. power feedthroughs, thermocouples, cooling tubes etc.
- Co-axial combinations of drives, providing up to five axes of independent rotation for sophisticated manipulation requirements
Standard to all MagiDrives
- Fail-safe functionality – with excess torque, a MagiDrive will simply release and lock back onto the next pole. This avoids possible costly damage, maintenance and downtime
- Bakeable to 250°C
- No bellows, organics or sliding seals
- True UHV performance
- High torque
- No backlash under low load and acceleration
- Magnetic shielding - this permits use in magnetically-sensitive environments
How it works
View the video link below. The mounting and rear flanges are fixed in position. The blue components show how the outer magnetic assembly is coupled with the inner magnets. The latter is part of the rotating shaft assembly.
