The utility model provides a commutator motor which can fully improve efficiency of a magnetic circuit provided with the commutator motor which adopts a stator core composed of directional electromagnetic steel plates, an electric blower and an electric dust collector. The commutator motor (3) comprises a stator (7) provided with the stator core (9) and an exciting winding (10), and a rotor (8) which is provided with an armature winding (17) and is configured at the inner side of the stator (7), wherein the stator core (9) is formed by laminating the belt-shaped directional electromagnetic steel plates (94), the directional electromagnetic steel plates (94) take the long edge direction as a direction of easy magnetization, a normal of the face of the directional electromagnetic steel plates (94) is vertical to a rotating shaft of the rotor (8), the stator core (9) is bounded by iron core partitioning surfaces (25a, 25B) to be partitioned into a first stator core (9A) and a second stator core (9B), and the iron core partitioning surfaces (25a, 25B) are arranged in the rear of a rotating direction of the rotor (8) relative to a magnetic pole center line of the stator (7) when observing from the direction of the rotating shaft of the rotor (8).
