Abstract

Sont divulgués dans la présente demande une structure de moteur, un moteur et un appareil de nettoyage. La structure de moteur comprend un boîtier, un ensemble stator et un ensemble rotor, l'ensemble stator et l'ensemble rotor étant agencés dans le boîtier. L'ensemble stator enveloppe l'ensemble rotor. Un espace de dissipation de chaleur est formé entre une extrémité de l'ensemble stator et la paroi interne du boîtier, une pièce de conduction de chaleur étant agencée dans l'espace de dissipation de chaleur. La structure de moteur selon la présente demande résout le problème selon lequel, étant donné que la chaleur générée par un enroulement de stator d'un moteur ne peut pas être dissipée dans le temps, l'augmentation de température du moteur est excessivement élevée et, par conséquent, le moteur ne peut pas fonctionner normalement ou peut même tomber en panne.
