The fail-safe permanent magnet clutch uses rare earth permanent magnets to generate the magnetic field to keep the clutch engaged, should the power fail.
This innovative permanent magnet clutch designed and manufactured by SG Transmission has the potential to replace the need to use both a clutch and a brake saving on space, weight and part count.
If the drive system uses a gearbox where the output shaft cannot be ‘back driven’ then, in some applications, by employing a permanent magnet clutch this mechanical advantage can be used to provide a positive stop/hold action in the event of a power failure.
The permanent magnet clutch design can be adapted to replace the existing ‘power on’ version, whi Read More...ch is not fail-safe, where applications need to be replaced retrospectively.
Existing footprint dimensions can be maintained, with just the need to make them slightly longer to incorporate the permanent magnets within the existing construction.
It is possible to utilise this technology in both flange mounted and bearing mounted clutch options, click here to make an enquiry.
