Abstract (en)
[origin: WO9103062A1] The aim of the invention is to simplify a rotating actuator (1) with a magnetic reset element (18), in particular for controlling the cross-section of a choke, and to improve the torque profile of the reset element (18). To this end, the reset element (18) is made of ferromagnetic material and arranged in the region of the permanent magnet segments (10) of the servomotor (2). The reset element (18) is asymmetrical, with three short arms (22 to 24) and a longer arm (5). In consequence, the maximum torque produced by the element (18) is reduced and the reset angle from which the element (18) returns to its desired locking position is increased. The rotating actuator (1) is particularly suitable as an idling rotating actuator in internal combustion engines.
