Abstract: A mobile machine includes front and rear ends, a frame, rotatably supported ground engaging mechanisms, and an electrical drive system. The electrical drive system includes a source of electrical energy, an inverter, at least one electric motor operatively coupled to rotate at least one of the ground engaging mechanisms, a plurality of first electric cables electrically coupling the source of electrical energy to the inverter, and a plurality of second electric cables electrically coupling the inverter to the electric motor. The inverter is disposed in the mobile machine in a vertical orientation at the rear end of the machine.

Abstract: A coil for a rotary electric machine includes a plurality of electrically conductive wires defining a group of wires wrapped to define a plurality of turns. The coil further includes a pair of major sections and a compound outer surface along the pair of major sections. The compound outer surface has a first leg section and a second leg section with the first leg section and the second leg section at an angle to each other. A bonding material is positioned along portions of the pair of major sections to define the compound outer surface.
