    摘要： An electrical machine includes a rotor that is rotatable about a rotation axis, and includes a stator having electrically conductive stator windings. The machine includes a cooling channel through for cooling the stator windings. The stator has teeth extending arranged at a distance from one another along a circumferential direction of the rotor, the stator teeth protruding inwardly and carrying the stator windings. An interspace is formed between two stator teeth which are adjacent in the circumferential direction. An interspace is arranged in an insulation body having outer walls composed of a plastic, which delimit a body interior, in which a winding zone and a channel zone are provided. A stator winding is arranged in the at least one winding zone of the insulation body and a cooling channel for a is arranged in the at least one channel zone of the insulation body.

    摘要： A method for producing a stator for an electrical machine may first include providing a stator having a ring-shaped stator body, from which a plurality of stator teeth arranged spaced apart from one another along a circumferential direction of the stator body, for accommodating stator windings, protrude, wherein a space, in each case, may be embodied between two stator teeth adjacent in the circumferential direction. The method then may include first injection molding at least two stator teeth, which are adjacent in the circumferential direction, with a plastic, arranging at least one stator winding in the space between the at least two stator teeth, and second injection molding the stator winding with the plastic, so that at least one of an air gap and an air trap formed between the at least two stator teeth first injection molded and the stator winding is filled with the plastic.

    摘要： A method for producing a stator for an electrical machine includes providing the stator including a ring-shaped stator body, from which a plurality of stator teeth arranged spaced apart along a circumferential direction of the stator body protrude radially to the inside. A space is thereby provided between two stator teeth adjacent to one another in the circumferential direction. Second, a first injection molding of two stator teeth adjacent to one another in the circumferential direction with a plastic is performed. Third, a stator winding is arranged in the space. Fourth, a second injection molding of the stator winding arranged in the space with the plastic is performed such that an air gap and/or an air trap between the stator teeth injection molded in the second step and the stator winding after the arrangement of the stator winding in the space in the third step, is filled with the plastic.

    摘要： An electrical machine may include a rotor rotatable about an axis of rotation, by way of which an axial direction of the electrical machine may be defined, a stator having electrically conductive stator windings, and at least one cooling channel through which a coolant may be flowable for cooling the stator windings. The stator may have stator teeth extending along the axial direction, arranged spaced apart from another along a circumferential direction of the rotor, and bearing the stator windings. The at least one cooling channel and at least one stator winding may be arranged in at least one intermediate space formed between two stator teeth adjacent in the circumferential direction. A plastic for transferring heat from the at least one stator winding to the at least one cooling channel may be arranged in the at least one intermediate space.
