The balancing of rotors for dynamo-electric machines (e. g., electric motor armatures) is achieved by attaching a balancing strip to the rotor after an impregnation resin has been applied to the wire coils, and the unbalance of the rotor has been measured. To create the balancing strip, a material supply selectively and incrementally delivers a predetermined quantity of material, such that the quantity of material has a mass sufficient to compensate for the measured unbalance of the rotor. The predetermined quantity of material is separated from the material supply to form a balancing mass, and the balancing mass attached to the rotor to compensate for the measured unbalance. A mounting member having a recess may be preliminarily attached to the rotor for subsequent attachment of the balancing mass thereto. A second material supply may be provided such that a controller can select between the first and second material supplies. |
