A commutator motor, an electric blower, a vacuum cleaner, and a commutator motor manufacturing method

Japanese Patent JP6020744

B2

This invention provides the following: a commutated motor that has a stator core using oriented magnetic steel sheets and makes it possible to substantially improve the efficiency of the magnetic circuit of said commutated motor; an electric fan; an electric vacuum cleaner; and a commutated-motor manufacturing method. This commutated motor (3) is provided with the following: a stator (7) that has a stator core (9) and a field winding (10); and a rotor (8) that has an armature winding (17) and is positioned inside the stator (7). The stator core (9) is formed by laminating together strip-shaped oriented magnetic steel sheets (94), the easy magnetization direction of each of said oriented magnetic steel sheets (94) being the lengthwise direction thereof, and normals to the surfaces of said oriented magnetic steel sheets (94) are perpendicular to the axis of rotation of the rotor (8). Core segmentation surfaces (25a, 25b) segment the stator core (9) into a first stator core (9A) and a second stator core (9B), and the number of oriented magnetic steel sheets (94) laminated together decreases with decreasing distance from said core segmentation surfaces (25a, 25b).
