    摘要: A motor-compressor unit for sub-sea applications, including a pressure casing, and an electric motor housed in a motor compartment formed in the pressure casing and a compressor housed in a compressor compartment formed in the pressure casing. A shaft drivingly connects the electric motor and the compressor. At least one magnetic bearing rotatingly supports the shaft and a control system is provided for controlling the magnetic bearing. The control system is housed in a control system compartment structurally connected to and supported by the pressure casing.

    摘要: To provide a vacuum pump in which possibilities of decreased exhaust performance and gas leakage at the time of breakage of a rotor are lessened, in the case where a rotating part closes the inside opening portion of an exhaust outlet portion to decrease the height dimension of the vacuum pump, and further a connector lead wire is installed easily. An inside opening edge portion of a gas discharge passage for combining the downstream space of the rotor with the exhaust outlet portion is caused to take a shape such that the opening edge portion has no blind portion when a gas exhaust passage forming member is viewed from at least either of an upper side or an oblique upper side, or from at least either of an lower side or an oblique lower side. Furthermore, the inner corner portion of this opening edge portion is formed into a rounded shape to reduce stress concentration. Also, a base is provided with a groove for combining a lead wire installing hole with a hole in the central part, and further the corners of these parts are formed into a rounded shape.
