摘要： A compressor unit comprises a centrifugal compressor for compressing a gas, having a rotor with one or more compressor impellers, and an electric motor having a stator and a rotor, for driving the rotor of the compressor. The compressor and the electric motor are accommodated in a common gas-tight housing which is provided with a gas inlet and a gas outlet. The rotor of the compressor and the rotor of the electric motor are arranged on a common rotor shaft which is mounted in magnetic bearings. The rotor shaft comprises a single unit and is mounted in two radial magnetic bearings, each in the vicinity of one end of the common rotor shaft, and one axial magnetic bearing, which is arranged in the vicinity of one of the radial bearings.

摘要： During the operation of an electrical machine, brush dust is generated as a result of a frictional wear of the brushes (5, 50), The brush dust is deposited in undesired locations of the electric machine and causes sparkovers or increased frictional resistance. In order to solve the above-mentioned problem, the invention provides for a brush dust collecting device (41) comprising a dust collecting bead (6, 13, 21, 42) mounted in direct plurality to the slip ring (1, 11, 23, 53).
