DEFINITION

Classification: 335/272

(under subclass 270) Subject matter wherein the armature is in the form of a disk or a cylindrical member and is mounted so that when the electromagnet is energized, the armature revolves on its support or about its center, within a plane perpendicular to the support means.

(1) Note. The rotation of the armature may be a complete revolution or a partial revolution.

(2) Note. This subclass does not provide for armatures mounted for pivotal movement such that the movement of the armature is not confined to a plane perpendicular to the support means, as in subclass 276, below.
