Abstract
(EN)
The present application provides a motor, an air supply device, and a household appliance. The motor comprises: a rotor structure; and a stator structure, detachably connected to the rotor structure, provided inside the rotor structure in a radial direction, and configured to drive the rotor structure to rotate. By means of the technical solution of the present application, when the motor is applied to drive a load to move, the load may be detached solely along with the rotor structure for cleaning or replacement, and therefore, it is convenient to operate; in addition, a stator iron core is provided in a circumferential direction of the rotor structure, thereby reducing the size of the whole motor in an axial direction and also realizing driving on the rotor structure in the circumferential direction to drive the load directly connected to the rotor to rotate.

La présente invention concerne un moteur, un dispositif d'alimentation en air et un appareil domestique. Le moteur comprend : une structure de rotor ; et une structure de stator, reliée de façon amovible à la structure de rotor, disposée à l'intérieur de la structure de rotor dans une direction radiale et conçue pour entraîner la structure de rotor en rotation. La solution technique de la présente invention permet, lorsque le moteur est appliqué pour entraîner une charge à déplacer, de détacher la charge uniquement le long de la structure de rotor à des fins de nettoyage ou de remplacement, par conséquent, son fonctionnement est pratique ; en outre, un noyau de fer de stator est disposé dans une direction circonférentielle de la structure de rotor, ce qui permet de réduire la taille de l'ensemble du moteur dans une direction axiale et de réaliser également un entraînement sur la structure de rotor dans la direction circonférentielle pour entraîner la charge directement reliée au rotor en rotation.
