An electrical machine includes housing surrounding a stator laminated core and a stator winding. Stator core support rings are arranged between the housing and the stator laminated core and radially surround the stator laminated core, with a cavity being formed between the housing, the stator laminated core and the stator core support rings. The stator laminated core has a cooling channel which is fluidically coupled with the cavity via a channel entry arranged centrally in the middle of the stator laminated core, thereby creating in conjunction with the channel entry a T-shaped form of the cooling channel so that a stream of coolant is not heated over an entire length of the stator laminated core, but only over a shorter stretch as a result of the T-shaped form.

Cooling of an electric machine

A stator arrangement for an electrical machine includes a casing element as one component and at least two stator segments, which are arranged in the casing element as further components. One of the components has a feather key groove and another one of the components has a feather key, which corresponds with the feather key groove, for bracing the one component against the other component.
