Abstract
A method for reducing leakage currents in an electric machine is described. The method includes positioning a plurality of leakage current shields between windings and teeth of a stator, and coupling at least one of the plurality of leakage current shields to a reference point, wherein an electric potential at the reference point is not earth ground.
