Abstract
(EN)
The present invention relates to an electrical machine comprising one ore several stators (20) edified by one or several statorpackages (21) that consists of one or several statorsections (22). The core (23) of the statorpackage is arranged to cooperate with a coil (24) which winding axis is parallel to the rotary axis (2) of the machine to obtain axially directed magnetic flux. Further, the machine comprises one or several rotordiscs (11) that are arranged on the rotary axis (2). The electrical machine according to the present application is in one embodiment provided with a ring-shaped statorwinding with large cross section area and small diameter which minimises the power losses and facilitates cooling. Large cross section area and consequently many ampere-turns will result in high effect per weight and volume unit for the machine.

Cette invention concerne une machine électrique comprenant un ou plusieurs ensembles stators (20), formés d'un ou de plusieurs stators individuels (21), lesdits stators individuels (21) étant eux-mêmes formés d'éléments (22) de stator. Le noyau (23) d'un stator individuel est conçu pour fonctionner en coopération avec une bobine (24) dont l'axe d'enroulement est parallèle à l'axe de rotation (2) de la machine afin d'obtenir un flux magnétique de direction axiale. Selon cette invention, la machine comprend également un ou plusieurs disques (11) de rotor placés sur l'axe de rotation (2). Selon un premier mode de réalisation de la présente application, la machine électrique est pourvue d'un enroulement de stator annulaire se caractérisant par une section transversale de grande surface et un faible diamètre, ce qui permet de minimiser les pertes de puissance et favorise le refroidissement. La section transversale de grande surface et les nombreuses spires qui en découlent, confèrent à la machine une performance élevée par unité de poids et de volume.
