FIELD: electricity.SUBSTANCE: invention relates to a square-cage rotor for an asynchronous motor. The rotor contains a laminated pack (1) with groves (3), cage rings (5) of the first material moulded at end surfaces to the laminated pack and conductors (4) of the second material with higher conductivity than the first material, at that the conductors are placed in the grooves. Surface of the conductors (4) has a coating (8) of the coating material which through the first doped layer (2) of the second material and coating material borders with the second material of the conductors (4) and through the second doped layer (9) of the first material and coating material border with the first moulded material.EFFECT: improvement of electrical efficiency for the square-cage rotor consisting of two materials.25 cl, 6 dwg |
