MECHANICAL SYSTEM AND ASSOCIATED MOTORCOMPRESSOR

Ce système mécanique (12) pour machine électrique tournante (20) comprend au moins un rotor (15) et au moins un arbre de transmission (16) pour dispositif mécanique (13). Le rotor est à arbre non traversant et comprend une masse magnétique cylindrique (21) enserrée entre un premier (22) et un deuxième (23) éléments de compaction rapportés formant un arbre rotorique, une extrémité de l'arbre de transmission étant reliée directement au premier élément de compaction. To reduce the weight and dimensions of a mechanical system due to the latest technology, increase the rotating speed of an electrical rotating machine incorporated in the system, and increase the overall performance and power of the system, thereby overcoming all or some of disadvantages of the system.SOLUTION: A mechanical system (12) for a rotary electrical machine (20) comprises at least one rotor (15) and at least one transmission shaft (16) for a mechanical device (13). The rotor has a non-penetrating shaft and comprises a cylindrical magnetic block (21) clamped between first (22) and second (23) raised compaction elements forming a rotor shaft. One end of the transmission shaft is connected directly to the first compaction element.SELECTED DRAWING: Figure 2
