A control device (10) for a linear actuator, particularly for the movement of sliding doors, the actuator (11) being of the type comprising a box-like body (12), to be fixed with corresponding means of fixing between the two jambs (S1, S2) of a door (P) or of a window or door frame, an electric motor (13) being accommodated within the box-like body (12) which actuates a rotor that is adapted to interact, by way of a window (15) defined on the box-like body (12), with a rail (16), which is fixed to a door (A) to be translationally moved, the box-like body (12) being coupled to the rail (16) by way of a slide (19) connected to the rail (16) in order to enable the relative sliding between box-like body (12) and rail (16), the device further comprising - a microprocessor (20) for commanding the electric motor (13), - an incremental encoder (21), rotary, on board the electric motor (13), defining the speed and the direction of motion of the rail (16) and of the door (A) to which it is fixed, - means for the safe use of the linear actuator (11) of which the control device (10) is part.
Abstract:
A guide (10) for a permanent-magnet linear actuator (11), of the type comprising a row of permanent magnets (12, 12a, 12b, 12c) which are arranged side by side and substantially parallel and equidistant. The guide (10) is constituted by a series of modular elements (13, 14, 14a) which can be interconnected in the direction of extension of the guide with interlocking means for simplified fixing.
Abstract:
An electric lock (10) for sliding doors or shutters, comprising an element (11) to be engaged which is adapted to protrude from an edge (12) of a sliding door or shutter (13) and is intended to be engaged and retained reversibly, in a stroke limit position for the door or shutter (13), by a reversible device (14) for automatic engagement and locking, which is fixed to the frame (15) of the sliding door or shutter (13).
Abstract:
A linear actuator (10), particularly for sliding doors and for sliding doors and windows in general, comprising a supporting body (11), to be fixed by corresponding fixing means between the two jambs (S1, S2) of a door (P) or of a door or window frame, motor drive means (12) being accommodated and fixed within the supporting body (11) and being adapted for the rotation of a driving gear (13), which is intended to mesh with a driven rack (14), which in turn is fixed to a leaf (A) of the door (P) to be moved in translation.
Abstract:
A rotor (10) for a permanent-magnet linear actuator (11), comprising a series of permanent magnets (12, 12a, 12b, 12c, 12d) which are supported by a shaft (13) associated with means for its rotation (14, 15), the permanent magnets being arranged laterally adjacent in the direction of the longitudinal axis (X) of the shaft, with polarities that are shifted out of phase, in succession, by a preset angle. Each permanent magnet (12, 12a, 12b, 12c, 12d) is constituted by a flat body which comprises a central portion (16) for fixing to the shaft (13) and at least two opposite symmetrical pole shoes (17, 18) which form the poles, with an external profile (19, 20) shaped like a circular arc.
