  • Patent number: 8904710
    Abstract: A door operator for operating a swing leaf in a door assembly. The door operator is configured to be mounted to a reception body such as a door transom, a wall or the like, and has a connector module for connecting with at least one connecting line. The connector module from a direction of the reception body and from at least one lateral direction, has at least one opening, through which the connecting line can be optionally guided to the connector module.
    Type: Grant

  • Patent number: 8695277
    Abstract: A door operator to be disposed at a door leaf, a door frame, a door transom, or a wall, with at least one mounting plate, on which the door operator assembly is disposed. The assembly has a modular design and has at least one connector module, a drive module and a main module, which are latched onto the mounting plate by latching elements. The main module includes a system carrier, which accommodates at least one supply unit and at least one control unit, fastened by latching elements.

  • Patent number: 8248005
    Abstract: A braking circuit is adapted to supply generatively produced energy of the motor as load resistance to a bipolar transistor. The braking circuit has a voltage regulator, which controls a voltage, applied to the base terminal of the bipolar transistor to achieve an associated controlled voltage based on a reference voltage. A first power supply connector of the electrical motor, in the generator mode of operation of the electrical motor, is coupled to a collector terminal of the bipolar transistor and to the voltage input of a voltage regulator. A second power supply connector of the electrical motor is coupled to an emitter terminal of the bipolar transistor and is coupled to a reference input of the voltage regulator via a resistive branch including at least one electrical resistor.
