Abstract

See full text

An electromagnetic drive unit for a switching device includes: a magnetic core with a first, a second, and a third magnetic path each arranged transversely with respect to a longitudinal axis of the electromagnetic drive unit and coupled to longitudinal magnetic struts at respective ends to form a magnetic frame structure; an armature movable along the longitudinal axis between a first and a second state; and a first and a second magnetic coil for moving the armature based on excitation of the first and/or the second magnetic coil. The first magnetic coil is arranged between the first and the second magnetic path and the second magnetic coil is arranged between the second and the third magnetic path with respect to the longitudinal axis. The magnetic core and the magnetic coils are arranged such that a magnetic flux that flows through the magnetic paths to move the armature is adjustable.
