Abstract:
PCT No. PCT/IB98/01361 Sec. 371 Date Jun. 28, 1999 Sec. 102(e) Date Jun. 28, 1999 PCT Filed Aug. 31, 1998 PCT Pub. No. WO99/13557 PCT Pub. Date Mar. 18, 1999An electromotive actuating device having a movable member and a stationary member is disclosed. The device includes a first excitation part adapted to generate a constant magnetic flux and a second excitation part adapted to generate a magnetic flux of variable amplitude, a first and a second magnetic circuit is provided for guiding the magnetic flux generated by the first excitation part. The reluctance of the first and of the second magnetic circuit is controlled by means of the position of the movable member, and the second excitation part being included in the second magnetic circuit. An actuating device of this type has a rotary actuator having a range of more than 90 DEG . This is achieved in that the stationary member includes at least a first pole shoe, a second pole shoe and a third pole shoe. The first pole shoe and the third pole shoe form flux guiding elements of the first magnetic circuit. The second pole shoe and the third pole shoe form flux guiding elements of the second magnetic circuit.
