Abstract
A brushless motor includes (a) a rotor magnet having plural magnetic polarities and (b) a stator core facing the rotor magnet via an annular space. The stator core has plural teeth wound by coils, and a teeth width ranges from not less than 1.7 mm to not more than 2.2 mm, or an outer diameter of the rotor core vs. the teeth width ranges from not less than 8 to not more than 12. This structure allows the brushless motor to rotate with less vibrations, lower noise and lower current consumption.
