Abstract: A method for controlling a temperature of an electric motor in a vehicle drive train via a fluid supply device having a closed fluid circuit with a fluid pump for conveying a fluid flow, which is to be supplied to the electric motor and which in the process alters its operating temperature. The method comprising comparing one actual value of a safety characteristic value of the electric motor to a predetermined limit value of the safety characteristic value. The method further comprising controlling the fluid flow by switching the fluid supply device between a first operating state and a second operating state at least according to the comparison. In the first operating state, the fluid flow is adjusted according to a predetermined operating characteristic value of the electric motor. In the second operating state, the fluid flow is adjusted so as to be higher than in the first operating state.

Abstract: A dynamoelectric machine having a stator having a substantially cylindrical or hollow-cylindrical stator body, a rotor arranged substantially coaxially with the stator, two ring elements, of which in each case one is arranged on each end face of the stator body. Each ring element has inlet nozzles through which a cooling fluid can be sprayed onto the winding heads of the stator. Penetration of the cooling fluid into the air gap of the machine is prevented in that each ring element radially and axially encloses the winding heads arranged on the respective end face, such that the winding heads are encased in an annular space bounded by the respective ring element and the respective end side of the stator body.

Abstract: A stator of a dynamoelectric rotary machine includes a stator body which has substantially axially extending slots, a stator winding, the conductors of which are located in the slots and spacers for positioning the conductors in the slots such that a cavity for the passage of a cooling medium that is continuous over the entire axial length of the slot, remains between the slot walls and the conductors. The stator body is a laminated core having stator sheets stacked axially on top of one another and intermediate sheets that act as spacers located between the stator sheets, the intermediate sheets being axially spaced apart from one another over a plurality of stator sheets and having retainers for retaining and positioning the conductors such that, between each pair of intermediate sheets, the conductors are positioned spaced apart from the walls of the slot in a free-floating manner.
