Abstract
An electric machine including multiple windings, a switch circuit connected to each of the windings, a positive bus bar, and a negative bus bar. The switch circuits are in communication with the windings to selectively energize each of the windings. The positive bus bar is a conductive plate connected to the switch circuits and the negative bus bar is a conductive plate positioned substantially parallel to the positive bus bar and connected electrically to the switch circuits.
