Abstract
An electric machine according to various aspects of the invention includes a transformer having a rotating component for transmitting power from a stationary portion of the machine to a rotating portion of the machine, or vice versa. Both the rotating component and a stationary component of the transformer includes a winding, wherein the windings are disposed to be magnetically coupled. Current provided to the winding of the stationary component generates a magnetic field, which induces current in the winding of the rotating component.
