Definitions

  • an outer rotor type motor comprising:
  • the air flow heated by the windings is exchanged with the first end cover and the second end cover by causing the air flow to rapidly circulate through the plurality of longitudinal passages on the stator yoke and the plurality of openings on the support portion.
  • Heat, and thus heat is dissipated into the external environment through the first end cap and the second end cap, so that the thermal resistance between the winding and the external environment can be significantly reduced, thereby significantly improving the heat dissipation effect of the hub motor.

Abstract

L'invention concerne un moteur à rotor externe (1) qui comprend : un arbre (10) ; un stator (20), entourant l'arbre et disposé de manière fixe sur l'arbre (10), le stator comprenant une culasse (21) et une partie de support (23) située sur un côté interne radial de la culasse, une pluralité de dents de bobinage (211) sont formées au niveau de la culasse, un bobinage (213) est enroulé sur chacune des dents de bobinage, et une pluralité d'ouvertures (233) sont formées sur la partie de support ; un rotor (30), entourant l'arbre et disposé sur un côté externe radial du stator ; un premier couvercle d'extrémité (40), porté de manière rotative sur l'arbre ; un second couvercle d'extrémité (50) porté de manière rotative sur l'arbre, le premier couvercle d'extrémité, le second couvercle d'extrémité et au moins une partie du rotor définissant ensemble un espace interne du moteur à rotor externe ; et des mécanismes d'entraînement d'écoulement d'air (45, 41, 51), pour amener l'air à passer à travers des espaces autour des bobinages et à travers la pluralité d'ouvertures de façon à circuler dans l'espace interne. La structure améliore l'effet de dissipation de chaleur du moteur à rotor externe.
