ROTOR OF ASYNCHRONOUS ELECTRIC MACHINE Russian patent published in 2011 - IPC H02K17/16 H02K17/22 H02K3/04 

FIELD: electricity.

SUBSTANCE: rotor of an asynchronous electric machine comprises a shaft, a ferromagnetic core fixed coaxially on the shaft - a magnetic conductor with an external surface in the form of a circular cylinder and an electric winding of "squirrel cage" type. At the same time according to this invention, the ferromagnetic core - magnetic conductor consists of longitudinal elements made of material having at least axial electroconductivity, besides, the longitudinal elements with the help of frontal conductors - links are electrically connected to each other only by their end parts, forming a winding of "squirrel cage" type.

EFFECT: considerable improvement of weight and dimension characteristics of an electric machine, reduced prime cost of its manufacturing, considerable reduction of teeth pulsations of the torque on the shaft of the asynchronous electric machine with a rotor made according to this invention.
