Abstract
An electromagnetic coupling device includes a vane member and an electromagnet. The electromagnet includes a core having a plurality of poles comprising at least four poles. An electrically conductive winding has a first portion surrounding a first one of the poles and a second portion surrounding a second one of the poles. The winding is selectively energized for selectively magnetically coupling the electromagnet and the vane member such that the vane member and the electromagnet are movable together in a desired direction.
