FIELD: engines and pumps.
SUBSTANCE: invention relates to a squirrel-cage rotor for an induction machine and to a method of its fabrication. The squirrel-cage rotor comprises a rotor core 1 of sheets, short-circuited rods 2 arranged inside the said core 1 and short-circuited rings 3 abutting on the said core 1 to electrically interconnect the said rods 2 at the rotor core end sides. For better heat removal, heat pipes 4 are fitted axially in the said rotor core 1 to extend therefore at end sides and to fit in the short-circuited rings 3.
EFFECT: better heat removal from the squirrel-cage rotor of the induction motor.
