Abstract (en)
[origin: EP2472126A1] The motor-compressor has a motor for rotating a rotor, and a compression stage comprising a set of paddle wheels (4) mounted on a driven shaft driven in rotation by the rotor. An assembly comprising the motor and a compressor is mounted in a common housing sealed to gas manipulated by the motor-compressor. The compression stage includes an adjusting element i.e. blade (13), for adjusting flowing angle of gas towards or from the wheels of the stage. The stage has a control motor (16) for controlling the adjusting element mounted in the housing.
