Abstract: A drive device for moving a leaf, in particular a door leaf or a window leaf, with an electric machine including an, in particular single, stator and an, in particular single, rotor, which can be rotated about a machine axis, and with a gear coupled to the electric machine. The gear has a first gear element, which can be rotated coaxially with the machine axis, with the first gear element being connected to the rotor in a rotationally-fixed manner.

Abstract: A drive device for pivoting a leaf, in particular a door leaf or window leaf, about a leaf axis, the drive device having a motor-transmission module, the motor-transmission module including an electric machine having a machine axis as well as a transmission having an output shaft that is mounted to be rotatable about an output axis. The electric machine is at least partially, in particular entirely, arranged in a mounting space between the leaf axis and the output axis.

Abstract: A method for pivoting a leaf from a closed position at an opening angle of 0° to an open position at an opening angle of greater than 0° and/or from the open position at the opening angle of greater than 0° to the closed position at the opening angle of 0° by a leaf torque, wherein the leaf toque has a manual torque, generated by a person, and a drive torque, wherein the drive torque is generated by a drive device with a drive module, a closer module and a controller module. The drive module has an electric machine having a stator and a rotor, wherein the closer module has an, in particular mechanical, energy storage, wherein the controller module has a controller device, wherein the drive torque has a machine torque generated by the electric machine and a closer torque generated by the closer module.

Abstract: A door actuator arrangement, comprising a door actuator having an output shaft, with the output shaft having a first face-side end and an opposing second face-side end, a linkage, whose linkage head is fitted on the first end of the output shaft and is connected to the output shaft in a rotationally fixed manner and a connection element. The connection element is connected or can be connected at the first end to the linkage head, protrudes into the output shaft and is accessible at the second end to make a connection between linkage head and output shaft.

Abstract: A door closer assembly includes a door closer without a powered drive for closing a door. The door closer includes an energy accumulator, wherein the energy accumulator is chargeable by manually opening the door and wherein the energy accumulator discharges for closing the door. A sensor unit is also included for detecting an angle information with regard to the opening angle of the door.
