Abstract

An electromagnetic actuator with an armature unit () that can be driven relative to a stationary core unit () in reaction to the application of current to a stationary coil unit (), which armature unit has a permanent magnetic agent () as well as a plunger unit (), designed so as to interact with an actuation partner, guided out of a magnetically flux-conducting housing (), wherein, on the outer surface of a shaft section () of the armature unit () a magnetically non-conducting bushing agent () is provided such that in a zero applied current state of the coil unit () a permanent magnetic flux () of the permanent magnetic agent () flows through the core unit () and the shaft section () so as to hold the armature unit () on the core unit (), and in a state of the core unit () in which current is applied the permanent magnetic flux () is displaced out of the core unit () into a housing section () of the housing and a permanent magnetic flux circuit is closed by a section () of the plunger unit facing towards the housing.
