SELF-BRAKING COUPLED AXIAL ASYNCHRONOUS MOTOR Russian patent published in 2018 - IPC H02K17/32 H02K9/06 

FIELD: electricity.

SUBSTANCE: coupled axial asynchronous motor comprises a stator and a rotor. The stator consists of a braking device, assembled symmetrical body in the form of an external cylindrical rim with side shields with bearings fixed on it, which is integrated with the central plate, on axial surfaces of which stator magnetic circuits with windings are fixed. The rotor consists of two packages in the form of ring rotor disks with ventilation flaps on exterior surfaces that contain rotor magnetic circuits with windings, with a brake spring established between them on the shaft with an opportunity of their axial moving along the axis. Inside the central plate a network of radial ventilation ducts is made, passing under the supporting surfaces of the stator magnetic circuits that connect the outer surface of stator body, coupled with the atmosphere, with the inner central vehicle cavity, which lies between the inner surface of the central plate and external side of the shaft and is aligned both with cavities, formed by external side of the shaft and the internal surfaces of stator magnetic circuits, and axial ventilating ducts passing along internal surfaces of rotors magnetic circuits, connected with a network of radial ventilating ducts passing under the supporting surfaces of rotors magnetic circuits, emerging on the external surfaces of the annular rotor discs.

EFFECT: increase the time of continuous operation, operational reliability and durability of the electric machine.
