FIELD: electricity.
SUBSTANCE: invention relates to electrical machine (1, 51), in particular, an asynchronous machine, and its cooling system. Electric machine (1, 51) includes stator (2), rotor (4) being in magnetic interaction with stator (2), shaft (5), fixed on which is rotor (4); the shaft has axial bore (6), feed element (7, 47), which passes through axial bore (6) so that to ensure possibility of cooling agent (15) flow from feed element (7, 47) into axial bore (6). Electric machine (1, 51) comprises chamber (32, 42), which is located at the open end of shaft (5) so that there is ensured a possibility of cooling agent (15) flow from axial bore (6) into chamber (32, 42). Chamber (32, 42) in axial direction is restricted by axial framework (320, 420), which ensures possibility of spiral guiding of cooling agent (15) around rotation axis (3) into output (33, 43) of cooling agent.
EFFECT: higher efficiency of machine cooling.
