Electromechanical machine e.g. permanent magnet synchronous motor, has rotor arranged in rotor area, whose boundary with exclusion of feed through of rotor shaft from rotor area is pressure sealed

摘要

The machine (1) has a housing (11) and rotor (2) arranged in a rotor area (23), whose boundary (4) with exclusion of a feed through (15) of a rotor shaft (20) from the rotor area is pressure sealed. The rotor shaft supporting the rotor is swivelably supported. A stator winding (30) partially surrounds the rotor. A limitation wall (40) is arranged the stator winding and the rotor and is attached at the housing or the housing part in a pressure sealed manner. A pipe (41) is made of a high-grade steel, non magnetizable or reduced magnetizable material such plastic.
