ROTOR OF THE ASYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2017 - IPC H02K17/16 H02K1/22 

FIELD: electricity.

SUBSTANCE: rotor of the asynchronous electric motor contains a core made in the form of a cylindrical laminated package with grooves and fixed to the shaft, a short-circuited winding made in the form of a squirrel cage design and containing rods of length l_δ, height h_C and width b_c located in the grooves of the core of the rotor, and short-circuiting rings located on the end surfaces of the core of the rotor. Short-circuiting rings are made with a radial height a_n and the axial thickness b_n. On even tines with length t₂ of the short-circuiting rings 4 in the radial direction, grooves of a rectangular shape of length l and depth h are arranged symmetrically with respect to the symmetry axes of the even gear divisions.

EFFECT: reliability increase.
