Claim 0:
1. An electric drive unit comprising:
a multi-phase electric motor having a stator and a rotor, the stator including a stator core and a plurality of field windings, each of the field windings being associated with a corresponding phase of electrical power, the rotor being rotatable relative to the stator about a motor axis; and
an inverter having a plurality of power semiconductors, an inverter mount, and a plurality of busbars, each of the power semiconductors having a plurality of terminals, the inverter mount having a base, the power semiconductors being mounted to the base of the inverter mount such that the terminals extend through the base and the power semiconductors are arranged in an annular manner, each of the busbars having a first busbar portion and a second busbar portion, the first busbar portion having a first body and a set of first fingers that are fixedly coupled to the first body, the second busbar portion having a second body and a set of second fingers that are fixedly coupled to the second body, wherein each of the fingers in the set of first fingers and a corresponding one of the fingers in the set of second fingers of each of the busbars is mechanically and electrically coupled to opposite sides of a corresponding one of the terminals of the power semiconductors;
wherein the busbars comprise a positive busbar, a ground busbar, and a plurality of phase busbars, each of the phase busbars being mechanically and electrically coupled to an associated one of the field windings.
