Abstract

An electric machine comprising a winding-carrying stator part (4) and an armature part (6) movable relative thereto. The stator poles (10) and their winding (12) are mounted on a stator support (8) of U-shaped cross-section. The stator support (8) has formed therein flow spaces (30, 32) for a cooling fluid (34) flowing at least across partial regions of the stator pole winding (12).
