ELECTROMAGNETIC DRIVE WITH A ROCKING ELEMENT, IN PARTICULAR FOR AN IMPACT PRINTER

摘要

The drive arrangement has a pivoted lever (1) comprising a piece of the same material as an armature web (1-2-1) which is formed by a certain section of the lever. The lever has at its free end a rinq-like structure (1-2) with an operating tooth (1-3). The electromagnet unit includes a yoke (2-1) extending perpendicular through the plane of movement of the lever and encircled by an excitation coil. The yoke is divided into two yokes on each side of the movement plane. Each yoke has ring segmental pole faces between which lie the working gaps (G1,G2).
