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.

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.

Electric rotary machine and drive arrangement

A hydraulic assembly of an electrically operable axle drive train having at least one electric machine and having a control unit, the hydraulic assembly including a first hydraulic pump for conveying a first hydraulic fluid from a hydraulic reservoir into a first hydraulic path, which is coupled to a first hydraulic connection point of a first switching valve, wherein the switching valve has a second hydraulic connection point, which is coupled to a second hydraulic path, the second hydraulic path connecting the second hydraulic connection point to a first cooling fluid connection point of the electric machine, and the electric machine including a second cooling fluid connection point, which is connected to a third hydraulic path coupled to a third connection point of the first switching valve, and wherein the first switching valve has a fourth hydraulic connection point, which is coupled to a fourth hydraulic path leading into the hydraulic reservoir.
