Abstract (en)
[origin: EP2306472A2] The actuator has permanent magnets (6) holding an anchor (12) in a de-energized condition of electromagnets (2). The permanent magnets are designed as a radial magnetized circular magnet and an anchor is designed as a hollow cylinder. A return plate (22) is arranged at a distance from the permanent magnets so that a permanent magnetic circuit is closed by the permanent magnets, the yoke (10), the return plate and the anchor in an end position of the anchor. Another permanent magnetic circuit is closed by the permanent magnets, yoke, anchor and a core (16) in another end position.
