Claims

[Scope of utility model registration request]

In a balance ring that is attached to the rotor shaft to maintain mechanical balance of the rotor of a rotating electrical machine and has a counterweight attached to it, circles that are concentric with the outer circumferential surface and arranged at appropriate intervals in the radial direction A balance ring for a rotating electrical machine, characterized in that a plurality of equal-sized counterweight mounting means are formed on the top at relatively short pitches.
