ABSTRACT:
A dynamoelectric machine having a rotatable commutator and a plurality of brushes mounted in brush holders is provided with a rigging assembly that operates to prevent the commutator from being forced into contact with the brush holders when the machine is subjected mechanical shocks. The brush holders are mounted on a yoke member that is resiliently biased to a predetermined spacing relative to the commutator. A limit stop on the yoke member is positioned to contact a spacer ring on the commutator when a mechanical shock forces the commutator toward the brush assemblies, thereby to prevent the commutator from contacting the brush assemblies.
