A linear motor arrangement for panels, in particular sliding door leaves, movable along a travel path, as well as to a device for mounting such an arrangement includes a linear drive system having at least one stator member of a linear motor and a connecting member as components. The connecting member comprises a circuitry. The components are consecutively disposed in a row. Furthermore, the connecting member has a housing, which, at one end, has at least one connection possibility for an external energy supply. In addition, the housing, respectively the connecting member is adapted, to receive circuitry, which has additional terminals. In order to be able to run connecting lines in the connecting member, a channel is configured in the housing such that they are led out of the housing at the end of the connection possibility.
Abstract:
A suspension for at least one panel, which is movable along a travel path, is has a guiding profile configured to longitudinally extend along the travel path and to have sidewall sections. The sidewall sections are configured to extend in a direction of the longitudinal extension of the guiding profile and parallel to a vertical extension of the movable panel. In addition, at an end facing away from the movable panel, the sidewall sections are connected to each other by means of a horizontal wall section. At an end facing the guiding profile, the at least one movable panel is received in a guided and supported manner in the guiding profile. A driver member of a linear drive system is operatively connected to the movable panel. In the guiding profile, in a space between the horizontal wall section and the driver member, a reception space is formed, into which a driving profile is fitted and stationarily mounted to the guiding profile, the linear drive system, at least partially, being accommodated in the driving profile and the driving profile being disposed in the guiding profile above a guide of the movable panel.
Abstract:
A linear motor is disclosed, which has a stator and at least one rotor, the stator having at least two stator modules. Each stator module has a coil arrangement and, seen in longitudinal extension of the respective stator module, at least at one end, a displacement sensor. Each stator module is disposed along a travel path of the respective rotor in an area of the respective stator module. Each displacement sensor has a detection range, within which it can detect a rotor, as long as the latter is located at least partially in the detection range. Each coil arrangement has an interaction range, within which, in case of energizing, the coil arrangement comes into interaction with the rotor and urges the latter in a driving direction, as long as the rotor is located with at least one portion in the interaction range. The at least two stator modules and the at least one rotor are disposed such that, at all times, a portion of the at least one rotor is located at least in the detection range of a displacement sensor and another portion of this rotor at least in the interaction range of a coil arrangement of the at least two stator modules.
Abstract:
A swing leaf operator having a closer portion is described. The closer portion has an output shaft, on which a cam disc is torsion-resistantly disposed, as well as a pressure roller. By way of an operational connection, a closer spring presses the pressure roller against a running surface of the cam disc. The pressure roller, with regard to an axial center of the output shaft, is disposed such that, during an opening or closing of a swing leaf coupled to the output shaft, the pressure roller is moved along a path. Due to the fact that the path bypasses the axial center of the output shaft and on account of the configuration of the running surface of the cam disc, in different modes of operation of the swing leaf operator at a respective opening angle of the swing leaf, a very similar or identical torque is respectively applied to the output shaft. Furthermore, the swing leaf operator has a drive motor, which is in operational connection with the output shaft.
Abstract:
A magnetic drive system for driving a door leaf in a driving direction is disclosed. The drive system includes a row of magnets disposed in the driving direction and having a longitudinal direction, the magnets being arranged so that magnetizations of the magnets reverse in accordance with a predetermined pattern; and a coil arrangement comprising a plurality of coil cores and a plurality of coils, the coils being wound around respective coil cores and spaced apart from each other in the longitudinal direction of the row of magnets. When energized, the coils interact with the magnets to generate a thrust force for driving the door leaf in the driving direction. The magnets in the row of magnets are disposed relative to the coil cores so that a total magnetization of the magnets has no abrupt polarity reversal in the driving direction with respect to the coil cores.
Abstract:
A drive unit for a door includes an electronically commutated multipole motor having: a stator part configured to be arrangable at a stationary structural component part; and a rotor part configured to be gearlessly connectable to a rotationally drivable element. The stator part and the rotor part include sheet metal elements stacked in a package-like manner. The sheet metal elements of the stator part and the sheet metal elements of the rotor part extend parallel to one another.
