摘要:
A power module assembly has a plurality of electrically conducting layers, including a first layer and a third layer. One or more electrically insulating layers are operatively connected to each of the plurality of electrically conducting layers. The electrically insulating layers include a second layer positioned between and configured to electrically isolate the first and the third layers. The first layer is configured to carry a first current flowing in a first direction. The third layer is configured to carry a second current flowing in a second direction opposite to the first direction, thereby reducing an inductance of the assembly. The electrically insulating layers may include a fourth layer positioned between and configured to electrically isolate the third layer and a fifth layer. The assembly results in a combined substrate and heat sink structure. The assembly eliminates the requirements for connections between separate substrate and heat sink structures.

A partially segmented rotor assembly for an electric motor and a method for the same is provided. The partially segmented rotor assembly includes a first rotor segment and a plurality of second rotor segments. The first rotor segment has a plurality of first poles wound with a wire and defines a first circumferential gap between the wire of each adjacent pair of the first poles. Each second rotor segment has a second pole wound with the wire and is rigidly attached to the first rotor segment in a respective one of the first circumferential gaps to form a plurality of second circumferential gaps between the wire of each first pole and the wire of the adjacent second poles. The first and second rotor segments are configured to cooperate with one another to minimize the second circumferential gaps.
