MANUFACTURING METHOD OF OUT-OF-ALIGNMENT SHORT-CIRCUITED ROTORS AND OUT-OF-ALIGNMENT SHORT-CIRCUITED ROTOR

摘要

FIELD: electricity.;SUBSTANCE: invention relates to electric engineering and can be used at manufacture of a short-circuited rotor of an asynchronous machine. The invention proposes a manufacturing method of short-circuited rotor (1) for asynchronous machine (2), which includes core (5) with bevelled slots (4), end rings (6) from the first material and short-circuited bars (3; 11; 12) from the second material with higher specific electric conductivity in comparison to the first material, which are moulded-on from faces to core (5) of the rotor, and which are laid into bevelled slots (4) of short-circuited rotor (1) and almost fully fill internal zone (7) of the slots if to look in radial direction of core (5) of the rotor.;EFFECT: increasing efficiency of an asynchronous machine.;24 cl, 10 dwg
