Abstract
A brushless motor includes a stator (26) having six slots (30), and a rotor having two poles. The rotor is adapted to rotate with respect to the stator. By adopting a 6-slots-2-poles structure, the brushless motor effectively reduces operational noise due to iron loss and unbalanced pull. As a result, the working life of the motor can be improved.
