The word "imbalance" is being used on Wikipedia in place of "rotating unbalance". Rotating unbalance is the correct term to use when describing a state of uneven distribution of mass about its rotational axis. Examples of rotating unbalance: an automobile tire freshly mounted to a tire rim prior to unbalance measurement and correction; a turbine engine rotor (disk) when it is first assembled with blades of unknown mass or moment weight, prior to unbalance measurement and correction; a turbine disk that becomes damaged during flight from an intrinsic flaw, or resulting from an inflight loss of a compressor or turbine blade from a bird strike, for instance.

Today, I made a minor edit to a Wikipedia page about the CF6 engine because it used the term "imbalance" when it should have used "rotating unbalance". This page on imbalance was referenced as the reason for rejecting my simple edit.
