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.

A rotary electric machine includes a bearing that holds a rotation shaft and is capable of rotating the rotation shaft, a housing accommodating the bearing, a rotor that is fixed to the rotation shaft and rotates, and a stator that is fixed to the housing. The stator includes a stator core including a tooth portion protruding toward the rotor and extending along the rotation shaft, a winding wound around the stator core, and magnetic detectors attached to an end portion of the stator core in a direction in which the rotation shaft extends while being separated from each other in a rotation direction of the rotation shaft.

An electric machine for arrangement in a transmission housing, having an adapter device, an axle connected to the adapter device, a rotor arranged on the axle by a bearing device so as to be rotatable about the axle, and a stator which surrounds the rotor in a circumferential direction and which is arrangeable spaced apart from the rotor, and at least partially fixable, in the adapter device, wherein the adapter device partially covers the rotor and/or the stator.

In manufacturing a motor, a second protrusion of a lead bushing is inserted into a second through-hole in a bearing holder. A diameter increased portion on an upper end of the second protrusion fixes the lead bushing to the bearing holder. This configuration thus requires less dimensional accuracy as compared with a case where the lead bushing is press fitted to the bearing holder.

An electrical machine, e.g., a power generator such as an alternator for a motor vehicle, is disclosed. The electrical machine includes a rotor and a stator, and the rotor is non-rotatably secured to a shaft having a shaft end that protrudes out of the rotor. A belt pulley is arranged at the shaft end for coupling to a drive. A bearing is non-rotatably secured to the shaft between the belt pulley and the rotor. A spacer ring is non-rotatably secured to the shaft between the belt pulley and the bearing. A gap which encircles the shaft is disposed between the belt pulley and the spacer ring, and between the spacer ring and the bearing, respectively. A plurality of blades directed radially outwards are arranged in at least one of the respective gaps. The blades convey incoming contaminated air to the outside and protect the respective gap against dirt.

A power transmission set for tractioned axles of vehicles. The power transmission set includes at least one coupling/uncoupling device, a selector unit, a primary shaft, and a secondary shaft. The shafts are interconnected by the selector unit to select and control a type of motor propulsion applied to a tread axle of a vehicle. The shafts cooperatively with the coupling/uncoupling device are configured to provide a configuration in which only a combustion engine is responsible for propulsion; in which only an electric motor provides propulsion; in which both the combustion engine and the electric motor work together to generate torque; or in which the tread axle is uncoupled from the combustion engine and the electric motor and the combustion engine provides power to the electric motor to generate electricity. A vehicle for the transport of cargo and passengers including the power transmission set.
