MOTOR WITH EXTERNAL ROTOR AND STATOR COOLING SYSTEM Russian patent published in 2019 - IPC H02K1/20 H02K5/20 H02K9/19 

FIELD: electrical engineering.

SUBSTANCE: invention relates to stator of inverted machine cooling. Electric motor with external rotor and stator cooling system includes static shaft installed in bearing support concentrically to which stator magnetic core is installed with working winding and its front flights. Electric motor is additionally equipped with hollow cylinder, inside of which stator magnetic conductor is installed. Cylinder comprises covers tightly connected with shaft and corresponding ends of cylinder, and two internal partitions forming cavities. Static shaft includes channels for supply and discharge of coolant, each of which is interconnected with cavity of cylinder located on side of bearing support. Cavity located on the side of the free end of the shaft is equipped with nozzles for supply and discharge of coolant.

EFFECT: technical result is increase in reliability and efficiency.
