Rotary armature solenoid

Abstract

A rotary solenoid, particularly for use in electronic teleprinters and the like, especially for attachment perforators, etc., in which most of the metal components may be fabricated in the form of stamped sheet metal structures rather than turned or machined components and which is relatively readily adaptable to automatic fabrication, the stator poles being in the form of stamped sheet metal laminations disposed in respective aligned stacks at opposite ends of an actuating coil and provided with respective bearing members, for the armature, disposed at the outer faces of the respective pole stacks, with each bearing member having an inwardly directed bearing boss extending into the adjacent stack and in engagement with the respective pole faces thereof to axially align the armature in operative position. The respective pole stacks are operatively connected by a pair of yoke plates, likewise formed as sheet metal stampings and extending between and connecting the respective pole stacks to effect a closing of the magnetic circuit of the rotary solenoid.
