Electrical linear drive, has inner stator actuated by coil, and outer stator provided for carrying out magnetic interference and arranged parallel and/or coaxial and at distance to wall of rotor, where wall is connected with operating unit

摘要

The drive has an inner stator (5) actuated by a field coil (9), and a rotor with a wall (8a). Permanent magnets (4) are arranged at the rotor, and the wall is arranged perpendicular to a direction of movement of the rotor. The wall is connected with an operating unit or a guide bolt for transmission of force. The magnets together with the stator form a magnetic circuit, and the rotor moves parallel to a longitudinal extension of the wall. An outer stator (1) is provided for carrying out a magnetic interference and arranged parallel and/or coaxial and at a distance to the wall.
