In a motor, an armature includes an annular yoke having an inner surface, and a plurality of teeth radially projecting individually from the inner surface of the annular yoke, and a rotor is rotatably provided inside the armature with a gap between the outer surface thereof and the inner surface of the armature. The armature and rotor is configured to have a first magnetic resistance facilitating reactive magnetic flux to flow through at least one tooth in a plurality of teeth to an adjacent tooth of the at least one tooth therein as compared with the reactive magnetic flux toward the rotor. The armature and rotor is configured to have a second magnetic resistance facilitating main magnetic flux based on the at least one pair of magnetic poles to flow toward a yoke of the armature as compared with the main magnetic flux toward at least one tooth close to the main magnetic flux. |
