Claim 18:
19. An electric vehicle comprising:
a frame; and
a powertrain assembly, attached to the frame and comprising a gearbox and a fractional-slot-winding motor, wherein:
the fractional-slot-winding motor has a primary axis and comprises a stator, a bus-bar assembly, and a plurality of coil units each extending through the stator,
the stator comprises a coil-interconnection side, a bus-bar side, a plurality of stator slots, and a plurality of fluid-passage slots,
the plurality of stator slots extends through the stator parallel to the primary axis between the coil-interconnection side and the bus-bar side such that stator slots in the plurality of stator slots are circumferentially offset from each other,
the plurality of fluid-passage slots extends through the stator between the coil-interconnection side and the bus-bar side such that fluid-passage slots in the plurality of fluid-passage slots are circumferentially offset from each other,
the plurality of fluid-passage slots is configured to provide a fluid flow between the coil-interconnection side and the bus-bar side,
the bus-bar assembly comprises a first bus bar, a second bus bar, and a third bus bar, adjacent to the bus-bar side of the stator,
each of the plurality of coil units is electrically coupled to at least one other of the plurality of coil units at the coil-interconnection side,
a first one of the plurality of coil units is electrically coupled to the first bus bar,
a second one of the plurality of coil units is electrically coupled to the second bus bar,
a third one of the plurality of coil units is electrically coupled to the third bus bar, and
an end of each of the plurality of coil units extending from the coil-interconnection side is radially offset closer to the primary axis than a portion of that one of the plurality of coil units protruding through the stator.
