Abstract: A rotor for an asynchronous machine includes a laminated rotor core which is made of a plurality of rotor laminations that are stacked in a longitudinal direction of the rotor, an intended rotational axis of the rotor running in the longitudinal direction; and a rotor cage that has a number of rotor bars, which run through the rotor laminations in the longitudinal direction, and at least one short circuit ring, which is arranged on a laminated rotor core end lying in the longitudinal direction such that the short circuit ring electrically connects the rotor bars together. The laminated rotor core contains at least one rotor lamination in a region at the end. This rotor lamination has a greater strength and/or a greater rigidity in a radial direction with respect to the rotational axis than the other rotor laminations.

Abstract: An electric motor including a stator body with a stator laminated core and a stator slot, wherein the stator slot has a slot wall with a slot wall insulation for electrical insulation, as well as at least one electrical conductor which is received by the stator slot, the slot wall insulation having a tooth-shaped configuration.

Abstract: An electric machine having a stator arranged in a machine housing and a rotor mounted rotatably relative to the stator about an axis of rotation, wherein the machine housing includes at least one coolant inlet port for supplying coolant to the machine housing and at least one coolant outlet port for draining coolant from the machine housing. It is provided that the coolant inlet port empties into a distribution annulus and several housing coolant ducts emerge from the distribution annulus and extend beyond the stator, when viewed in the axial direction, and are connected fluidically, on their side facing away from the distribution annulus, to stator cooling duct inlets of stator cooling ducts formed in the stator, which pass entirely through the stator in the axial direction.

Abstract: A rotor for an electric machine having a rotor shaft, a winding support coupled to the rotor shaft in rotationally fixed manner, and at least one winding arranged on the winding support or a squirrel cage arranged on the winding support, wherein the rotor includes at least one heat pipe running at an angle to the rotor shaft.

Abstract: An electrical machine with a rotor and a stator. The rotor or the stator has at least one coil with a coil core and a coil winding, which surrounds the coil core. The coil winding has at least one turn that is formed from a flat conductor, which is bent a around a plurality of bending axes, which are spaced apart from one another and are parallel, and, as viewed in section, is S-shaped and/or has a meandering shape. The flat conductor has a plurality of layers that are insulated from one another, at least in regions, and/or a plurality of slot-shaped recesses.

Abstract: A rotor for an electric machine. A laminated core with a plurality of short-circuit bars that pass through it and are joined at both ends by way of a respective short-circuit ring. A support disc, which is made of a material that has a higher strength than the material of the short-circuit ring, is axially arranged at each short-circuit ring.

Abstract: A method for producing a short circuit rotor, by providing a laminated rotor core with through openings for shorting bars of a squirrel cage as well as providing the shorting bars; inserting of the shorting bars into the through openings such that an axial overhang remains on both sides; placing a main disk with through openings on both sides for the shorting bars, whose axial length corresponds to the overhang, as well as an edge disk immediately adjacent to the main disk and the ends of the shorting bars. The main disk and the edge disk form a shorting ring of the squirrel cage, and the main disk and the edge disk are welded by radially encircling electron beam welding.
