The invention relates to a Koepe winder or drum winder comprising an electric motor (5) for driving winding ropes (11). The rotor (6) of said motor is connected to the cylinder jacket (4) of the Koepe winder (2) and the stator frame (7) is fixed on a support structure that has a hollow shaft (3). The winder is characterised by an improved ventilation system. The motor (5) is located inside the cylinder jacket (4) in a cavity (12) between the plates (13) of the Koepe winder (2), said cavity being supplied with cooling air to ventilate the motor (5) from the exterior. The hollow shaft (3) is formed by two half-shafts (18, 19), which together with at least one support disc (8) and the stator frame (7) form the support structure (10).
La présente invention concerne une machine d'extraction à poulie motrice ou à tambour comprenant un moteur électrique (5) destiné à entraîner des câbles d'extraction (11), dont le rotor (6) est relié à l'enveloppe cylindrique (4) de la poulie motrice (2) et dont l'armature de stator (7) est fixée à une structure porteuse présentant un axe creux (3), ladite machine se caractérisant par un système d'aération amélioré. Selon l'invention, le moteur (5) est disposé à l'intérieur de l'enveloppe cylindrique (4), entre les plaques (13) de la poulie motrice (2), dans un espace creux (12) qui peut recevoir de l'air frais destiné à l'aération extérieure du moteur (5). L'axe creux (3) est selon l'invention formé de deux demi-axes (18, 19) qui forment la structure porteuse (10) avec au moins une plaque de support (8) et l'armature de stator (7).
