Title: ELECTRICAL MACHINE WITH COOLING
Abstract:
The invention relates to an electrical machine (1) with cooling, comprising a stator (4) surrounded by a housing (2). The stator (4) has a plurality of stator teeth (8) extending in the radial direction (R) towards a rotor (6). Furthermore, a yoke (10) connecting the stator teeth (8) is positioned such that multiple first clearances (11) are formed between the housing (2) and the yoke (10) and multiple second clearances (12) are formed between the yoke (10) and a free end (14) of the stator teeth (8). A coolant conduit (20) is in planar heat-conducting contact with at least one axial lateral surface (16) of the yoke (10).
