FIELD: electrical engineering.SUBSTANCE: machine comprises external rotor and stator (2) fitted inside rotor (3). Rotor comprises rotor bearing element (4), rotor plates (5) and permanent magnets (6). Rotor supporting element (4) comprises first radially extending part (7) and second part (8) extending axially connected therewith. Supporting element second part (8) supports rotor plates (5) and permanent magnets (6). Stator (2) has stator plates (9) and windings (10). Said windings make head parts (11, 12) extending axially from both sides above stator plates (9). Besides, it has impeller wheel (14) connected with rotor supporting element (4). Impeller wheel (14) is arranged between winding heads (11) located at axial side of stator (2) and second part of supporting part (8).EFFECT: power increase accompanied with small axial length and optimum air cooling in the zone of rotor and stator.18 cl, 4 dwg |
