UHV Magnetically Coupled Rotary Drives
Magnetically coupled rotary drives utilise a high strength magnetic coupling to transfer rotational forces into the vacuum environment. These drives are fitted with samarium cobalt magnets and can withstand excessive torque. Due to the lack of bellows, the drives have a long service life and do not risk a vacuum leak.
Rotary drives are used where a vacuum process requires a sample or components to be accurately rotated within the vacuum chamber. This can range from something as simple as spinning an attenuating chopper wheel, to accurately moving a sample to face from one analyser to another.
