Abstract:
1. A brushless motor having full-pitch windings in three phases, said motor comprising a rotor and a stator, said stator having an axial direction, the stator comprising a stator core comprising a plurality of coils, a yoke, teeth, and slots each located between a pair of adjacent teeth, the teeth being three times in number of poles of the rotor, wherein each of said coils of each phase is located in one of the slots in a one coil per one slot manner, the coils each having coil ends shaped in the axial direction of the stator, wherein the coil ends of each coil of said plurality of coils corresponding to a phase are located at an end surface of the stator core such that: a first coil is located outside the second and third coils, in a place where the second and third coils are located in a pair of slots adjacent each other; the second coil is located from inside the first coil to outside the third coil, in a place where the first and third coils are located in another pair of slots adjacent each other; and the third coil is located inside the first and second coils, in a place where the first and second coils are located in still another pair of slots adjacent each other.
