Patent number: 12341409Abstract: An electric rotary machine and a drive arrangement for a motor vehicle. The electric rotary machine having a rotor that rotates about an axis of rotation, a stator, a fluid supply device arranged statically fixed and a distribution element fluidically connected to the fluid supply device and rotatable relative thereto. The fluid supply device has a flow channel with an outlet for discharging cooling fluid in an outlet direction, and an axis of rotation of the distribution element is arranged such that the outlet direction runs tangentially to a circumference of the distribution element so the cooling fluid exiting the outlet can flow tangentially against the distribution element which can be set in rotation based on the incident flow, so the cooling fluid can be distributed around the axis of rotation. Large-area cooling is achieved in a structurally simple manner.Type: GrantFiled: May 6, 2021Date of Patent: June 24, 2025Assignee: Schaeffler Technologies AG & Co.

Publication number: 20240333101Abstract: 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.Type: ApplicationFiled: July 4, 2022Publication date: October 3, 2024Applicant: Schaeffler Technologies AG & Co.

Publication number: 20240195251Abstract: 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.Type: ApplicationFiled: February 23, 2022Publication date: June 13, 2024Applicant: Schaeffler Technologies AG & Co.

Publication number: 20230378836Abstract: An electromagnetic element for an electric machine, having multiple slots arranged in the circumferential direction of the electromagnetic element, said slots extending in the axial direction of the electromagnetic element and having an open side in the radial direction. A coil device is arranged in the slots, said coil device having winding heads on (at least) one axial end face of the electromagnetic element, and a cooling channel is formed in the slots in order to dispense heat from the coil device using a fluid. A wall element is also provided which has a first region that is arranged in the region of the winding head in the circumferential direction. and a second region of the wall element, said second region adjoining the first region and having teeth which extend in the axial direction and are arranged on the open side of the slots in the intermediate spaces between the slots in the circumferential direction.Type: ApplicationFiled: October 4, 2021Publication date: November 23, 2023Applicant: Schaeffler Technologies AG & Co.

Publication number: 20230179050Abstract: A cooling device for an electrical drive unit, includes a static feed element which has a coolant feed. The coolant feed has at least one supply channel running along a longitudinal axis of the feed element and multiple outlet channels which are distributed around a circumference of the feed element, run transversely to the supply channel, and emerge from the feed element. A distributor ring, which can rotate relative to the feed element and is designed for coolant distribution, is held on the feed element. The distributor ring is designed and adapted to the outlet channels of the feed element such that the distributor ring is driven directly in a rotary manner by a coolant flow emerging from the outlet channels during operation.Type: ApplicationFiled: February 18, 2021Publication date: June 8, 2023Applicant: Schaeffler Technologies AG & Co.
