A stator for an axial flux motor having a laminated stator core which is fastened to a flange, wherein the laminated stator core has a rear side which is interlockingly and frictionally fastened to a front side of the flange, and/or a cooling channel between the laminated stator core and the flange is formed in the region of the fastening. An axial flux motor is also provided having a rotor which is arranged between two stators, of which one or both are as described above.

Stator for axial flux motor having interlocking and frictional connection and axial flux motor in I-arrangement and direct line cooling

A rotor of an electric rotating machine, more particularly an axial flux machine, and an electric rotating machine equipped therewith. The rotor of the electric rotating machine, more particularly an axial flux machine, includes a plurality of magnets and a magnet carrier for fixing the magnets, with which carrier the magnets are positioned on a periphery with respect to a hub of the rotor. The magnet carrier extends radially outwards further than the magnets and has a first axial width at the periphery of the positioning of the magnets and forms a widened portion radially outside the magnets which has a second axial width which is greater than the first axial width. Using the rotor proposed here and the electric rotating machine equipped therewith, devices can be provided which, in a simple and cost-effective manner, guarantee efficient and low-wear operation.

Rotor of an electric rotating machine, and electric rotating machine

A method for producing a stator for an electrical machine, the stator having a substantially hollow-cylindrical stator core, which has a plurality of grooves spaced apart in a circumferential direction, the method including: providing at least one strip-shaped winding unit having a first winding conductor with a plurality of groove portions running straight in a transverse direction that are mutually parallel; fastening a first end of the winding unit to a lateral surface of a mandrel; winding the winding unit onto the mandrel such that it is bent around the lateral surface of the mandrel spirally; inserting the mandrel, together with the winding unit, into a cavity in the stator core; and unwinding the winding unit from the mandrel with the groove portions of the winding unit being inserted into the grooves of the stator core.
