FIELD: electricity.
SUBSTANCE: proposed electric machine including stator (1), rotor (2) having shaft (3) that is equipped with radial and axial cooling channels (10, 11) and acts like a paddle-blade fan, as well as axial fan (12) located coaxially to shaft (3) and supplies cooling agent to axial cooling channels (11). Axial fan (12) is made in the form of a double axial fan and equipped with the first rim (14) of blades, which is enclosed inside funnel-shaped pipe (15) and connected to it so that it cannot be rotated. Smaller hole of funnel-shaped pipe (15) is in close proximity to axial cooling channels (11) of rotor (2). Besides, axial fan (12) is equipped with the second rim (19) of blades, which is rigidly fixed on external perimetre of pipe (15) and serves for delivery of cooling agent (1). Therefore, effective cooling both of a stator and a rotor with a cooling agent flow is provided.
EFFECT: improving cooling efficiency of electric machines.
