Claims

[Scope of utility model registration request]

(1) In a squirrel-cage rotor for an induction machine, which has an end ring that short-circuits a bar and its both end faces as a conductor of the rotor, the bar and the end ring are connected by mechanical rotational friction welding. induction machine.

(2) The induction machine according to claim 1, which is a registered utility model, characterized in that a groove is provided on the end face of the bar along the direction of rotation during friction welding.

(3) The induction machine according to claim 1 or 2 of the utility model registration, characterized in that a concentric groove is provided at a position where the end ring rubs against the bar on the end face of the end ring.
