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： 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.
