1. A motor controller comprising:
- an inverter module comprising;
an inverter circuit with a first and second broad face;
a baseplate having a first broad face coupled to the first broad face of the inverter circuit, a second broad face, and a plurality of cooling features extending from the second broad face of the baseplate;
a cooling channel, comprising an inlet and an outlet, that is configured to receive a cooling fluid, wherein the cooling channel is cooperatively defined by a raised portion of a case accommodating the inverter circuit and by the second broad face of the baseplate, wherein the cooling features extend into the cooling channel such that the cooling fluid flows across the cooling features;
a capacitor; and
a laminated bus electrically coupling the capacitor to the inverter circuit and thermally coupling the capacitor to the cooling channel.

21. A motor controller comprising:
-
an inverter module comprising; an inverter circuit with a first and second broad face; a baseplate having a first broad face coupled to the first broad face of the inverter circuit, a second broad face, and a plurality of cylindrical tubes extending from the second broad face of the baseplate and arranged in a matrix; a thermal interface between the inverter circuit and the baseplate; and an electric insulator between the inverter circuit and the baseplate a reservoir, comprising an inlet and an outlet, that is configured to receive a cooling fluid, wherein the reservoir is cooperatively defined by a raised portion of a case accommodating the inverter circuit and by the second broad face of the baseplate, wherein the cylindrical tubes extend into the reservoir such that the cooling fluid flows across the cylindrical tubes, wherein the reservoir facilitates one-way flow from the inlet to the outlet, wherein the reservoir has substantially the same length and width as the inverter circuit; a capacitor; and a laminated bus electrically coupling the capacitor to the inverter circuit and thermally coupling the capacitor to the reservoir, wherein the laminated bus extends along a wall of the reservoir and underneath a flat end of the capacitor.
