摘要： 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.

摘要： A unit mounting in a vehicle, in which a drive unit is attached via a unit bearing to a body-side bearing bracket, which unit bearing is a rubber-metal bearing having a sleeve-shaped bearing core, which is screwed together with the body-side bearing bracket by a bearing bolt guided through the sleeve-shaped bearing core. The drive unit has a unit housing, in which a bearing receptacle is formed for the unit bearing. The housing-side bearing receptacle is formed as a bearing cup open on one side having a hollow cylindrical receptacle space, specifically in particular having a closed bearing base, from which a cylindrical circumferential peripheral wall is raised.

摘要： 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.

摘要： A method for producing a component for an electric machine from a laminated core, which includes multiple grooves and a central axis, and a plurality of wire elements. Each wire element includes two legs made of wire, which are or will be connected to one another via a bend made of wire. At least the legs of the wire elements are arranged in parallel to the axis in the grooves. A temperature sensor is fastened at a bend of at least one wire element.

摘要： An electrical machine having a winding support having multiple grooves, which carries at least one winding. The winding is formed by a conductor which has multiple groove sections which each extend within one of the grooves of the winding support and which are conductively connected by connecting sections of the conductor, which are outside the grooves. The conductor has an insulation layer applied to the conductor at least in the groove sections. The insulation layer has layer thicknesses different from one another for at least two of the groove sections.

摘要： A rotor for an electric machine, having a laminated core, which is arranged on a shaft and provided with magnets. Multiple individual adjoining plates pushed onto a shaft or of partial laminated cores having multiple plates have a central borehole accommodating the shaft. At least a part of the plates or partial laminated cores are pushed onto the shaft pivoted by a predetermined pivot angle (α). Every plate or partial laminated core includes multiple coolant passages arranged distributed around the center (Z) of the borehole. The angle offset of two adjacent coolant passages corresponds to the pivot angle (α).

摘要： 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.

摘要： An electrical machine, including a winding carrier, which has a multiple grooves and bears at least one winding. Each winding is formed by a conductor having multiple groove portions, which are led through respective grooves of the winding carrier and conductively connected by connection portions of the conductor that lie outside of the grooves; when current flows through the conductor in question from a first connection point to a second connection point of the winding in question, the current is led about an axis of rotation of the electrical machine with a first direction of revolution in all the connection portions that lie in a first conductor portion of said conductor, which first conductor portion includes multiple connection portions, and with a second direction of revolution opposite the first direction of revolution in all the connection portions that lie in a second conductor portion of said conductor.
