The machine has a sleeved assembly with electrical connections (108) connected to outside of the machine by a flexible/rigid electric supply duct (112). The connections pass from the assembly to the duct by passing in succession through two hermetically sealed bushings (104a, 114a) that co-operate with each other. The connections pass to the outside of the machine from the duct by passing through a third hermetically sealed bushing (116a) mounted on a connection part (116) secured to an end of the duct. The bushings are not exposed to a pressurized gas. The assembly is chosen from a sleeved magnetic bearing, a sleeved detector for a magnetic bearing, and a sleeved electric motor. |
