ACTUATOR DEVICE

Abstract

actuator device (1) comprising an actuator housing (4); at least two parallel bearing screws (3A, 3B), each supported by rotary bearings in the actuator housing (4) and coupled by rotary means (7A, 7B, 9A, 9B) to an electric motor (8A, 8B) and engaged with a bearing nut (12A, 12B), wherein the rotation of the bearing screws (3A, 3B) generates axial displacement of the bearing nuts (12A, 12B) along the bearing screws (3A, 3B), a drive element (13) engaged with the bearing nuts (12A, 12B), and a drive spindle (2) anchored in the drive element (13), and wherein a sensor head (15A, 15B) is accommodated on the drive element (13) near each bearing nut (12A, 12B), and a sensor of linear position (14A, 14B), contactless,It is fixed in the actuator housing (4) adjacent to each of the sensor heads (15A, 15B) and is arranged to communicate information about the position of the respective sensor head (15A, 15B) to the control system (17).
