Claims

[Scope of utility model registration request]

A variable rotation speed compressor that operates in a wide range from low to high speed by changing the rotation speed as necessary, has a part of the circumference of the end ring of the rotor of the motor as a convex part in the thickness direction of the end ring, A rotor for a variable rotation speed compressor, characterized in that a notched ring having an inner diameter, an outer diameter, and a thickness substantially the same as the convex portion and having a specific gravity different from that of the end ring is attached to the other circumferential portion almost without gaps. structure.
