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.
Claims20
A cleaner comprising:
- a flux switching motor,
- wherein the flux switching motor comprises:
- a rotating shaft;
- a rotor rotatable around the rotating shaft and comprising a plurality of rotor teeth;
- and
- a stator positioned to surround the rotor and comprising:
- a plurality of stator teeth provided to face the plurality of rotor teeth with an air gap therebetween;
- a plurality of armature slots and a plurality of field magnet slots alternately arranged in a circumferential direction with respect to the rotating shaft;
- a plurality of magnets, each of the plurality of magnets disposed in a respective filed slot of the plurality of field magnet slots;
- and
- a plurality of armature coils, each armature coil provided to be wound on armature slots adjacent to a field magnet slot to surround a magnet in the field magnet slot, and
- wherein the stator is provided such that a length of the stator in an axial direction in which the rotating shaft extends is shorter than a length of the magnet in the axial direction, and
- wherein the rotor is provided such that a length of the rotor in the axial direction is less than or equal to the length of the stator in the axial direction.
