Abstract (en)
[origin: WO03004878A1] Electric motor driveable compressor (1), in which the electric motor includes a rotor with rotor shaft (20), which acts in cooperation with a stator (50) provided in the motor housing (52, 56, 58, 60), the rotor shaft (20) being mounted on the motor housing (56, 58, 60) via at least two bearings (46) and connected fixed against rotation with the compressor wheel (10) at an axial receiving segment (30), wherein the rotating components, comprised essentially of the rotor with rotor shaft (20) and compressor wheel (10), are so designed, that their first critical bending fundamental frequency w1 lies above the maximal operationally occurring rotation speed nmax.
