1. A stator assembly, comprising:
a stator core including a back yoke disposed in an annular shape and a plurality of teeth extending from the back yoke toward a central axis of the annular shape;
an insulator disposed to sandwich the stator core from a top and bottom thereof; and
a coil conductor wound around a portion of the insulator that covers the plurality of teeth,
wherein the plurality of teeth include N teeth from a first tooth to an N-th tooth for each of a U-phase, a V-phase, and a W-phase, which are repeatedly arranged in order along the annular shape, where N is a natural number,
wherein the coil conductor includes a respective coil conductor for each of the U-phase, the V-phase, and the W-phase,
wherein the coil conductor in each phase has a first end configured as a terminal wiring conductor and a second end configured as a neutral-point connection conductor, and the terminal wiring conductor and the neutral-point connection conductor are connected by tooth conductors wound around teeth among the N teeth and a bridging line conductor that bridges the tooth conductors wound around the teeth,
wherein the terminal wiring conductor is connected to a first tooth conductor among the N teeth at an upper side of the insulator,
wherein the bridging line conductor is disposed on the upper side of the insulator disposed on the stator core and is disposed along an outer side of a tooth of a different phase, and
wherein the neutral-point connection conductor is connected to an N-th tooth conductor among the N teeth at a lower side of the insulator.
