Abstract
In an inner-rotor motor, an armature includes a stator core including an annular core back and magnetic pole teeth projecting from the core back; an insulator covering an upper and lower surface of each magnetic pole tooth of the stator core; and coils defined by a conducting wire wound around a separate one of the magnetic pole teeth with the insulator intervening therebetween. The insulator includes at least one protruding portion. An upper end of each protruding portion is arranged at an axial level higher than an axial level of a lower surface of a circuit board. The circuit board includes at least one penetration portion each of which is defined by a cut or a hole, and in each of which a corresponding one of the at least one protruding portion is arranged.
