ABSTRACT:
A rotor assembly (10, 20) for use in a dynamoelectric machine such as an electric motor has counterweights (18, 28) installed on it to reduce vibrations when the machine is in use. Apparatus (30) is for attaching a counterweight to each end of the assembly to reduce machine vibrations when in use. The apparatus comprises a support (32) on which the rotor assembly and counterweights are installed. The counterweights are installed in a predetermined relationship with the assembly so when they are attached, an unbalanced rotor assembly is produced. The rotor assembly is mounted in a predetermined position on the support. The support is indexed from a first station (S1) at which the rotor assembly and counterweights are installed on the support to a second station (S2) at which the counterweights are attached to the respective ends of the assembly. A press (36) is movable relative to the support, when it is at the second station, for pressing the rotor assembly and counterweights together and attach the counterweights to the respective ends of the assembly.
