1. A fractional-slot-winding motor having a primary axis, the fractional-slot-winding motor comprising:
a stator comprising a coil-interconnection side, a bus-bar side, and a plurality of stator slots, wherein the plurality of stator slots extend through the stator parallel to the primary axis between the coil-interconnection side and the bus-bar side and circumferentially offset from each other; and
a plurality of coil units, each extending through the stator, wherein:
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, 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, defined as a radial offset, than a portion of that one of the plurality of coil units protruding through the stator.
