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.

Electrical machine, in particular for a vehicle with a cooling channel for cooling stator windings

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.

Electrical machine for a vehicle

An insulating body for an electric machine includes outer walls of a plastic, which delimit a body interior. In the body interior, at least one winding zone for receiving a stator winding and at least one passage zone for receiving a cooling passage are provided.

Insulating body for an electric machine

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.

Insulation body for an electrical machine

A stator for an electric machine comprising a rotor and stator poles. At least one partial amount of stator poles each comprises a pole winding and a permanent magnet unit. A first magnetic flux induced by the permanent magnet unit is superimposed by a second magnetic flux is an electric voltage is applied to the pole winding or an electrical current is injected into the pole winding. A recess is arranged in the permanent magnet unit, which recess faces the rotor. An electric machine comprising a stator according to the invention, wherein the rotor is designed to change a magnetic resistance of a magnetic circuit, which extends through a permanent magnet unit of stator poles of the stator, according to the position of the rotor.
