ELECTRICAL MACHINE Russian patent published in 2018 - IPC H02K9/06 H02K5/18 

FIELD: machine building.

SUBSTANCE: invention relates to electromechanical construction, in particular to structures of electric machines with external blowing of the ribbed body, and can be used, for example, in asynchronous general-purpose engines. Electric machine contains an end shield, shaft and fan consisting of a hub, blades, disc serving as a stiffening bar, a guide for air flow and a base for the vanes. Shaft has an axial hole from the seat depth to the depth of the fan and a hole in the radial direction through the fan hub and a wall of a hollow part of the shaft of the electrical machine between the disc and the end shield. Hole from the end of the shaft is made in the form of radial-axial slots at the end of the shaft to the depth of the seat depth of the fan.

EFFECT: improved manufacturability of technological design.
