Claims

[Scope of utility model registration request]

In the rotor of a squirrel cage induction machine, in which an end ring is fixed to the end of a rotor conductor inserted into the rotor core, and a support ring is attached to the outer periphery of the end ring, the outer periphery of the end ring is A plurality of protrusions are provided on the support ring, and a circumferential groove into which the protrusions can be fitted is provided on the inner periphery of the support ring. An axial groove for removing the support ring is provided, and the support ring is inserted into the circumferential groove with the axial groove aligned with the protrusion of the end ring, and then the support ring is rotated by a predetermined angle. A rotor for a squirrel-cage induction machine, characterized in that the end ring and the support ring are shrunk-fitted to stop movement in the axial and circumferential directions.
