Abstract: An electric motor comprises: a motor housing, a stator connected to the motor housing, wherein the stator comprises first stator end-windings and second stator end-windings, a rotor rotatable relative to the stator, a driveshaft connected to the rotor in a rotationally fixed manner, wherein the driveshaft is rotatably supported in the motor housing about an axis of rotation, wherein an axial cooling arrangement is arranged axially adjacent and radially overlapping one of the first and second stator end-windings, wherein the axial cooling arrangement comprises a fluid chamber with a plurality of nozzles distributed in circumferential direction and directed towards said one of the first and second stator end-windings.

Abstract: A stator or rotor for an electric motor or generator comprising a plurality of teeth for receiving coil windings, wherein each tooth has an injection molded plastic layer formed on a plurality of sides of each tooth with a first gap formed in the injection molded plastic layer on a first side of each of the teeth with a first insulation element placed in the first gap formed in the injection molded plastic layer, wherein the injection molded plastic layer and first insulation element are arranged to electrically insulate the plurality of teeth from the coil windings.

Abstract: A stator or rotor for an electric motor or generator comprising a circumferential support having a protrusion; a tooth arranged to receive coil windings, wherein the tooth includes a recess in which is housed the protrusion of the circumferential support, and the protrusion and the recess in the tooth are arranged to have a cavity or channel formed on an adjacent surface of the recess and the protrusion when the protrusion is housed in the recess, wherein a material is placed inside the cavities or channels formed by the adjacent surfaces of the recess and the protrusion for retaining the tooth to the support.
