FIELD: electricity.
SUBSTANCE: electric machine contains a stator (1), a rotor (2), an external blower (3), the stator core (1) assembled of electrotechnical steel sheets designed as having concentric projections (9) within the outer diameter zone with ventilation holes (10) therein. During the stator assembly each sequential sheet (group of sheets) of the stator core is tangentially shifted relative to the preceding sheet (group of sheets) by a distance of the pitch of ventilation holes (10) in the core sheets concentric projections (9). Envisaged in the structural element (6) for the stator support on the external blower (3) side are air-directing enclosures (14), ventilation holes (16) and windows (15) for cooling air passage.
EFFECT: electric machine cooling improvement.
