  • MACHINE AND METHOD FOR RUNNING A MACHINE
    Publication number: 20250001564
    Abstract: A machine and a method for drilling a hole or setting a screw is provided, wherein the machine comprises a motor having a shaft and one or more magnetic coils, providing electric current to the one or more magnetic coils to rotationally drive the shaft, and switching the electric current at a commutation frequency to define a rotational speed of the shaft. A signal may be generated when a force towards the machine applied to the shaft increases and/or a torque applied to the shaft increases and the rotational speed of the motor may be increased to a first rotational speed when the signal is received. The rotational speed may be at least 6,800 RPM and at most 8,500 RPM.

  • FASTENING DEVICE
    Publication number: 20220259848
    Abstract: A device for fastening a first object to a second object in a fastening direction is provided, the device comprising an anchoring element, a tension element and a prestressing element, wherein the anchoring element is provided to be anchored in a fastening direction in the second object, wherein the tension element is provided to transmit a tensile force from the anchoring element to the prestressing element to prestress the prestressing element in the fastening direction against the first object, and wherein the tension element comprises a composite of a plurality of fibers.
