Brushless motor










Image Number 7 for United States Patent #8022589.

Teeth of a stator core are arranged one after another in the circumferential direction at alternating first and second pitches. Each corresponding adjacent two of the teeth, which are spaced from each other by the first pitch, are wound with corresponding two, respectively, of stator coils, which form a corresponding common phase. Each corresponding adjacent two of the teeth, which are spaced from each other by the second pitch, are wound with corresponding two, respectively, of the stator coils, which form corresponding different phases, respectively.
