Electromagnetic oscillation generator for oscillating conveying device - has armature between opposing pole faces of magnetic core with air-gap at each end

摘要

The oscillation generator has a magnetic core (6) enclosed by an energising winding (7) and a cooperating armature (8), spaced from its pole faces. The magnetic core and the armature are coupled via springs allowing relative oscillation. The magnetic core comprises a C-shaped yoke with two opposing pole faces (9,9') the armature positioned between them, with an air-gap (11,11') between each pole face and the respective end face (10,10') of the armature, the latter oscillating along the width of the air-gaps. ADVANTAGE - Uniform force delivery, preventing impact of armature with magnetic core for relatively inside oscillation.
