FIELD: electricity.
SUBSTANCE: electric engine comprises a stator, a rotor and a rotor circulating cooling circuit, containing a cylinder side surface shaped cover (2). The axial recess (12) is grooved for simplicity the inner circulating cooling circuit of he rotor in the cover (2). Inside the housing (1) there is a quill cylinder-shaped stator pack (10) with slots (18) on the outside surface. There are cooling ducts (22) in the slots (18). The stator pack (10) has the expanded axial recesses (20) on its outside surface. These recesses are a part of the rotor circulating cooling circuit.
EFFECT: cooling construction simplification.
