An eddy current coupling for a dynamo-electric machine. A flux path between a rotating drive shaft and a rotatable driven shaft includes an inductor drum connected to the drive shaft and a pole assembly coupled to the driven shaft. A coil assembly partially surrounded by the pole assembly controls the degree of electromagnetic coupling. A series of interdigitated pole fingers are spaced between the inductor drum and the field coil assembly to facilitate air flow that dissipates heat caused by relative rotation between the inductor drum and the pole assembly. The coil assembly includes an annular coil support co-axial with the driven shaft to support an annular field coil in a gap defined by the pole assembly.
