INDUCTION MOTOR ROTOR Russian patent published in 2024 - IPC H02K1/32 H02K17/16 H02K44/12 H02K9/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to electrical machines, and can be used in the field of induction electrical machines. Rotor of the induction electric motor is a laminated magnetic conductor arranged on the axis of rotation and having the shape of a cylinder. In slots of magnetic conductor of rotor of induction electric motor there are hollow tubes open at both ends and made of material with electric insulating properties. Rotor is placed in a tightly closed capsule so that at both ends of the magnetic conductor of the rotor between the magnetic conductor and the walls of the tightly closed capsule there are gaps filled together with the inner space of the hollow tubes with a liquid or gaseous electroconductive substance.

EFFECT: improved reliability and manufacturability of induction motor squirrel-cage rotor manufacturing.
