Brushless motor

A brushless motor comprising:

• a stator including an annular stator core and first through twelfth teeth provided circumferentially on an inner circumference of the stator core in a sequential order;
• first through twelfth coils wound around the first through twelfth teeth, respectively, and forming a delta connection;
• and
• a rotor provided at a center of the stator, wherein
• the first through twelfth coils are configured such that:
• the twelfth, first, six, and seventh coils in series connection form a W-phase;
• the eighth, ninth, second, and third coils in series connection form a U-phase,
• the fourth, fifth, tenth, and eleventh coils in series connection form a V-phase,
• coils of different phases adjacent to each other in an arrangement on the teeth are wound in the same direction,
• coils of the same phase adjacent to each other are wound in opposite directions,
• the W-phase includes a first connecting wire connecting the first coil and the sixth coil,
• the U-phase includes a second connecting wire connecting the ninth coil and the second coil, and
• the V-phase includes a third connecting wire connecting the fifth coil and the tenth coil.
