BSL's Rex MagneLink drive coupling comprises two separated hubs: one
containing a permanent magnet rotor, the other a conductor; both are
separated by a 1/8in air gap. This arrangement ensures that motor and
load are decoupled and that the driven shafts are isolated from one
another, thus protecting connected equipment from any over-torque
condition or excessive vibration. The coupling also provides soft
start/stop, enabling drive train selection to be based on operating, not
starting torque. The hub design allows many shaft types and sizes to be
accommodated, and enables different driver/driven shaft diameters to be
implemented on certain sizes.
