Abstract: A brushless direct current motor of an electrical machining device includes a stator, a rotor, a fan and a flywheel. The rotor, the fan and the flywheel are arranged for conjoint rotation on a motor shaft of the brushless direct current motor. The flywheel is at least partly surrounded axially along the motor shaft by the fan. The brushless direct current motor may be incorporated in a hand-held power tool.

Abstract: An axial flux machine, in particular a single-sided axial flux motor, for an electrical machining device, has a machine shaft, in particular a motor shaft, a disc-shaped stator, a disc-shaped rotor which is arranged adjacent to the stator in the axial direction of the machine shaft. The stator is formed as a winding carrier for at least one stator winding and the rotor, which is connected to the machine shaft in a rotationally fixed manner, can be set in a rotational movement relative to the stator, and with a housing for receiving the stator and the rotor. A first bearing, in particular a fixed bearing, is integrated directly into the winding support and/or into a first stator yoke for mounting the machine shaft. An electrical processing device with an axial flux machine is also disclosed.

Abstract: An electric power tool includes an output shaft, drivable by an associated drive motor, and a brake apparatus for braking the output shaft rotating in the unpowered state of the associated drive motor. The output shaft is mounted in a rotatable manner in an associated housing and the brake apparatus has a magnetic-field brake unit with at least one first and one second brake element. The first brake element is arranged radially with respect to the output shaft in a rotationally fixed manner in the associated housing and includes at least one first and one second magnetic pole configured to generate a magnetic field that alternates in the circumferential direction of the output shaft. The second brake element is magnetically conductive and rotationally connected to the output shaft via an activatable coupling device.

Abstract: An electrical power tool has an electronically commutated drive motor, preferably a direct current motor. The motor includes a stator core equipped with an insulating body, on which core a motor winding is embodied. Also included in the motor is at least one electrically conductive connector element for electrical connection of the motor winding, the connector element being disposed on the insulating body. The connector element has a fastening segment, and a receptacle for reception of the fastening segment is provided on the insulating body. The fastening segment and the receptacle have complementary geometrical shapes that prevent self-actuated detachment of the fastening segment disposed in the receptacle.
