Abstract
A motor includes a shaft, an annular rotor magnet, an armature arranged to cover the rotor magnet, an upper bracket fixed to an axial upper portion of the armature, and a lower bracket fixed to an axial lower portion of the armature. The armature includes an annular core-back, a plurality of magnetic pole teeth protruding radially inward from the core-back, an insulator arranged to cover the magnetic pole teeth, and a coil wound around the magnetic pole teeth through the insulator. The insulator includes an annular core-back insulating portion arranged radially outward of the coil and extended axially upward. The upper bracket is fixed by a plurality of fixing members positioned radially inward of an outer circumferential surface of the core-back.
