A cooling arrangement for cooling a stator for an electric machine. The cooling arrangement comprising a stator fixedly mounted relative to a rotational axis. The stator comprises a stator yoke and stator grooves. Windings are provided in the stator grooves, which form first and second winding heads. First and second fluid rings are provided at opposite ends on the stator yoke. The first fluid ring has a fluid inflow opening from a stator housing. The stator yoke has a plurality of axial stator ducts extending in the axial direction, which enable the inflowing fluid to flow through from the first fluid ring to the second fluid ring, and the second fluid ring redirects some of the fluid.

Cooling arrangement for cooling a stator for an electric motor

A stator (1a, 1 b) for an electric machine. The stator (,) is fixedly mounted relative to a rotational axis (Rot). The stator () comprises a stator yoke () that extends in the axial (A) and radial (R) directions. Stator teeth (), facing toward the rotational axis (Rot), are arranged in a ring shape on the stator yoke (). The teeth are uniformly spaced apart from one another so that a stator groove () is formed therebetween. The stator (,) is divided into a first stator section () and a second stator section (). First and second outer walls () are provided on the stator yoke () and serve to axially support the stator yoke (). A cooling manifold disk () is integrated between the first stator section () and the second stator section (). An electric machine with a stator of that type is also disclosed.
