Claims

[Scope of utility model registration request]

A rotor conductor is inserted into a slot in a rotor core made of laminated thin plates, and a shallow groove is formed on the inner surface of an end ring, and the end of the rotor conductor is fixed by brazing within the shallow groove. A squirrel-cage rotor, characterized in that an inner circumferential end of the rotor conductor is brought into contact with an inner circumferential edge step of the shallow groove.
