Abstract
A permanent magnet coupler has a conductor rotor assembly mounted on one shaft and a magnet rotor assembly mounted on a coaxial shaft. The magnet rotor assembly provides two magnet rotors spaced by the adjustable air gaps from two conductor elements provided by the conductor rotor assembly. The air gap adjustment includes adjustable stops, such, for example, as swing arms having an adjustable effective length. These stops operate in conjunction with swing arms causing the magnet rotors to move axially in unison in opposite directions. The air gaps are set so that the coupler will automatically release when subjected to an overloaded condition.
