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.

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.

A device is provided for activating a synchronous machine arranged in a vehicle. The vehicle has a gearbox and driven wheels in operative connection therewith. The synchronous machine is designed to drive the driven wheels via the gearbox. In the vehicle there is a lubricating unit, which is designed to lubricate the gearbox by way of a lubricant, for this purpose the lubricant flowing through the gearbox and at least part of the synchronous machine. The device is configured to operate the synchronous machine in a heating operating mode, which is different from a customary driving operating mode, when there are defined conditions that require heating when starting. At least one operating variable of the synchronous machine is set in the heating operating mode specifically such that, in the synchronous machine, there is a greater current heat loss in comparison with the customary driving operating mode, in order in this way to heat up the lubricant in the heating operating mode.
