Kind Code:
A1
Abstract:
A squirrel-cage rotor (3) used in an induction motor comprises: a core (7) laminated to a cylindrical shape; slots (6) formed within a radial position of the core (7); conductor bars (4) formed in the slots (6); conductor end rings (31a, 31b) disposed on both axial end surfaces of the core (7) and connected to the conductor bars (4); and ring-shaped coated materials (21a, 21b) formed by spraying conductive particles (43) in a solid phase state from an outer peripheral direction or an end surface direction of the conductor end rings (31a, 31b) with a shaft (10) or a sleeve fitted in an inner circumferential portion of the core (7), so that the coated materials are integrated with the conductor end rings (31a, 31b) and the shaft (10) or the sleeve.
