Abstract

A stator for an electrical machine, in particular for an electromotive drive machine for an electric or hybrid vehicle, includes a stator core stack with a stator yoke and a number of radial stator teeth, as well as a corresponding number of stator slots, arranged between the stator teeth, for receiving a stator winding. A cooling apparatus has a number of cooling channels, each of which runs axially in one of the stator slots.
