A salient pole rotor includes a rotor core which has a rotor yoke and salient poles arranged distributed over the rotor yoke in the circumferential direction, magnetic field-generating windings which are wound around rotor teeth of the salient poles and form end windings at opposite end sides of the rotor core, and a support device for supporting the end windings. The support device has a clamping and deflecting device and a roving winding with a roving by way of which a plurality of turns offset in the circumferential direction and encompassing the windings of a respective salient pole pair are formed and which for this purpose has axial first roving portions and end-side second roving portions. The second roving portions are guided over the end windings for forming a turn between radially opposite salient poles and are deflected along the circumferential direction for forming an interturn transition between two turns.

A rotor position sensor for a motor vehicle for sensing the rotational position of a rotor of an electric motor includes a sensor housing, in which the components of the rotor position sensor are accommodated. At least part of the sensor housing forms a cover for closing a motor housing of the electric motor.

Rotor position sensor and motor assembly

A rotor for an electric machine includes a rotor main body which has at least two poles between which in the circumferential direction of the rotor is disposed at least one pole gap, and a rotor shaft which is coupled in a rotationally fixed manner to the rotor main body. The rotor has a support device which has a covering body that is configured for covering at least regions of an end side of the rotor main body. The support device has an annular body, which is different from the covering body, and in the direction of radial extent of the rotor is braced in relation to the rotor main body, on the one hand, and in the direction of radial extent of the rotor is braced in relation to the covering body, on the other hand.

The present disclosure provides a screw and a screw assemblage. The screw includes a screw head and a screw shaft which protrudes from an underside of the screw head and has a self-forming or self-cutting thread, wherein the underside of the screw head has a bearing area and at least one annular recess extending around the shaft between the bearing area and the shaft, wherein a coating made of an elastic sealant is attached to the underside of the screw head.

A rotor shaft for an electric machine includes a rotor shaft main body and a rotor shaft core which is arranged therein and which is connected to the rotor shaft main body. The rotor shaft comprises a substantially axially running cooling cavity configured to conduct a cooling fluid, and the rotor shaft core is composed of a different material than the rotor shaft main body.

A stator for an electrical machine, in particular for an electromotive drive machine for an electric or hybrid vehicle, includes a stator core stack with a stator yoke and a number of radial stator teeth, as well as a corresponding number of stator slots, arranged between the stator teeth, for receiving a stator winding. A cooling apparatus has a number of cooling channels, each of which runs axially in one of the stator slots.

Stator of an electrical machine and cooling apparatus for same

An electric machine has a housing and has a stator inside the housing, surrounding a rotor arranged on a motor shaft so as to be fixed to the shaft. A rotary field winding, at the ends of the stator, forms a winding head. The winding heads are embedded in a thermally conductive encapsulation material, wherein the encapsulation material is in thermal contact with the housing along the outer circumference of the winding head. A segmented cooling plate is arranged on the inner circumference of the encapsulation winding head.
