Abstract: The present disclosure relates to a flux switching motor capable of realizing all a high output, a miniaturization, and an extremely light weight. In the flux switching motor, a stator is provided such that a length thereof in an axial direction in which a rotating shaft extends is shorter than a length of each magnet in the axial direction, and a rotor is provided such that a length thereof in the axial direction is less than or equal to the length of the stator in the axial direction.

Abstract: A small sized drive motor that achieves both high output including high-speed rotation and weight reduction is realized. Provided is a drive motor rotating in a predetermined direction. The drive motor includes a rotor having no magnet and including a plurality of salient poles. A stator core includes a plurality of element cores and a plurality of magnets. The salient poles are formed with a slit or a void (e.g., a second air gap)). The salient poles include a large magnetic circuit (a first magnetic circuit) on a front side of the slit in the rotational direction and having a large cross-sectional area and a small magnetic circuit a second magnetic circuit) on a rear side of the slit in the rotational direction and having a small cross-sectional area.

Abstract: A fan motor of a cleaner capable of exhibiting a high output is provided. The fan motor includes a shroud disposed to cover a fan, a rotor fixed to a shaft, and a stator disposed opposite to the rotor in an axial direction with a predetermined gap therebetween. The stator includes a substrate on which a bearing is installed and a plurality of armatures disposed around the bearing. A coil is formed in such a way that a flat wire having a rectangular cross-section is bent to a short side thereof to be wound around an iron core.
