COMMUTATOR MOTOR, VACUUM CLEANER AND HAND DRIER

PROBLEM TO BE SOLVED: To obtain a commutator motor having an efficient magnetic circuit. SOLUTION: The commutator motor includes: a stator 20 having a magnetic pole formed on an inner circumferential portion; an armature 10 having a winding 12 wound around an armature core 11 and turnably arranged on the inner circumferential portion side of the stator 20; a commutator 5 having the winding 12 connected thereto; and a brush 6 contacting the commutator 5. The armature core 11 is configured by arranging a plurality of armature pieces 101-10n so as to be continue in a circle, and the armature pieces 101-10n are configured of a directional electromagnetic steel plate having a magnetization easy direction directed toward the radius direction of the armature 10.
