Abstract (en)
[origin: WO2008022726A1] In a rotating-slide vacuum pump or compressor having a rotor (6) which can rotate in a housing (2) and is driven by a drive shaft, and having slides (8) which can be moved outwards in the circumferential direction herein in slots (7) in the rotor (6) and separate individual feed chambers of a working area (9), which is provided with an intake opening (1) and an outlet opening, from one another, and each assume a maximum outer position adjacent to the housing inner wall, driven by centrifugal force, the arrangement is designed such that a brushless disc-rotor synchronous motor (11, 12) is fitted in the axial direction to the rotor shaft.
