FIELD: electrical engineering.SUBSTANCE: electric machine consists of outer case (2) containing bottom (2b) located in fact perpendicular to rotor rotation axis; stator (3) having at least one pole extension (5) and at least one circular winding (8) installed inside the pole extension (5) and rotor (2); at that the case (2) has at least one support area (11) for interaction with respective area (12) of the winding (8) supporting it for the purpose of heat exchange between winding (8) and support area (11); meanwhile the area (12) of winding (8) is insulated electrically from the support area (11) provided that areas (11, 12) interact. At that according to this invention the support area (11) is formed by protrusion (13) of the bottom (2b) oriented inward of the electrical machine (1).EFFECT: increase of reliability and utilisation efficiency of available produced energy by means of its losses reduction.20 cl, 6 dwg |
