The commutator rotates as part of the armature, which has the fan blades fitted on the end of its central shaft. Power to the armature windings is supplied via the brushes.

From any point on the armature, the brushes appear to rotate around, it so the answer to your question was yes. That's what I meant by relativistically. (Blame Einstein.)
