<p>A two-phase brushless motor has a rotor comprising at least a pair of first magnetic poles and a pair of second magnetic poles which are smaller in width than the first magnetic poles, and a stator comprising at least a pair of first coils and a pair of second coils for producing a first phase and a second phase of varying magnetic fields, respectively, so that the torques respectively obtained from the interaction of the two pairs of magnetic poles and the two phases produced by the two pairs of coils differ from each other.</p> |
