1. A rotating electric machine comprising:
a stator including
a stator core including a yoke portion having a cylindrical shape and twelve teeth each protruding radially inward from the yoke portion, and
coils of three phases, a winding being concentratedly wound around each of the teeth to form each of the coils; and
a rotor rotatable relative to the stator, a number of poles of the rotor being two, wherein
the teeth include two teeth located adjacent to each other in a circumferential direction and forming a teeth portion, and the windings of a same phase are respectively wound in a same direction and such that current flowing directions through the windings are the same around the two teeth forming the teeth portion and are connected in series, and
the teeth are arranged such that the teeth portions adjacent to each other are different in phase and the three phases are arranged sequentially side by side in the circumferential direction.
