Problems solved by technology

[0002] At present, the commonly used fan motor is composed of a stator and a rotor that are set inside and outside each other. When the motor is driven externally, the stator drives the rotor and then drives the motor's shaft to rotate to realize the operation of the fan blades or other loads. The stator and the rotor are arranged coaxially. , and it is necessary to form a closed structure in the circumferential direction, and the rotating shaft will protrude outward in the axial direction, so that due to the limitation of the structure of the motor itself, the size of the entire product in the axial direction will be increased, and the mutual position of the stator and the rotor Inflexible, not conducive to the lightweight design of the product

Abstract

The invention provides a motor, an air supply device and a household appliance, and the motor comprises a rotor structure; a stator structure which is detachably connected with the rotor structure, wherein the stator structure is arranged on the inner side of the rotor structure in the radial direction and used for driving the rotor structure to rotate. According to the technical scheme, when themotor is applied to drive the load to move, the load and the rotor structure can be independently detached together to be cleaned or replaced, operation is convenient; in addition, the stator iron core is arranged in the circumferential direction of the rotor structure; on the one hand, the size of the whole motor in the axial direction can be reduced; on the other hand, the rotor structure can bedriven in the circumferential direction so as to drive a load directly connected with the rotor to rotate.
