Abstract
The invention relates to an actuator device comprising a headpiece (1) with an adjuster mechanism for an actuating arm mounted to pivot on the headpiece into the actuated and open position and a housing (7) supporting the headpiece (1) with an interior for housing a linearly adjustable control rod connected to the adjuster mechanism (3) and connected to the actuator arranged in the housing (7). According to the invention, the housing (7) is in the form of an extrusion moulded hollow profile (8), the interior of which has a constant inner cross-section over the entire length thereof.
Claims7
1-11. (canceled)
The arrangement according to claim 1,
- wherein an average angle between two alternatingly magnetized permanent magnet segments (3) of the rotor (2) corresponds to an average angle between two alternatingly magnetized permanent magnet segments (7) of the stator (5).
An arrangement for generating a nonlinear force and/or torque characteristic curve, comprising
- a cylindrical iron rotor (2) and a stator (5),
- the cylindrical iron rotor 2) having a periphery,
- permanent magnet segments (3) alternatingly magnetized in opposite directions and forming poles, arranged on the periphery of the cylindrical iron rotor (2),
- the stator (5) made of iron or a magnetic sheet metal laminate and having on its inner circumference permanent magnet segments (7) alternatingly magnetized in opposite directions and forming poles, and
- iron poles (4;
- 6) are provided between the permanent magnet segments of the rotor (2) and/or stator (5) having different polarization.
