The aim of the invention is to improve the production, design, and effectiveness of rollers or roller motors. Said aim is achieved by using a plastic support unit for the individual magnets in order to produce a multipole motor that has a small diameter and can be integrated into a roller. Said plastic support unit can be unscrewed after being incorporated into a return tube. Additionally, a roller comprising an integrated roller motor (24) is cooled by means of an external or internal cooling device (25, 26) so as to increase constant torque. Furthermore, in order to reduce the design of rollers which have to be braked as well, a braking device is provided which can be integrated into the roller. And finally, in order to simplify contacting of the stator during the production thereof, a divisible arbor is provided which comprises corresponding contact supports on both parts of the arbor.

L'objet de la présente invention est l'amélioration de la fabrication, de la taille et du rendement de rouleaux et plus particulièrement de moteurs pour rouleaux. A cet effet, pour fabriquer un moteur à faible vitesse de rotation et de petit diamètre, pouvant être intégré dans un rouleau, est utilisé un dispositif de support en plastique pour les aimants individuels, qui peut être éliminé par alésage au tour après montage dans un tube de reflux. En outre, selon la présente invention, pour augmenter le couple continu, un rouleau pourvu d'un moteur (24) de rouleau intégré est refroidi par un dispositif de refroidissement (25, 26) externe ou interne. De surcroît, si la taille des rouleaux qui doivent également être freinés doit être réduite, un dispositif de freinage peut être intégré dans le rouleau. Enfin, pour simplifier la mise en contact du stator lors de sa fabrication, est utilisé un axe divisible qui possède des supports de contact correspondants sur les deux parties d'axe.
