FIELD: machine building.
SUBSTANCE: machine includes housing 7, electric motor 4, at least one impeller 11, at least two radial bearings 17, 18, at least one shaft 5 passing along longitudinal axis 6, which carries at least one impeller 11 and rotor 15 of electric motor 4. Shaft 5 is installed in radial bearings 17, 18. Besides, electric motor 4 has stator 16 enveloping at least partially rotor 15 in the zone of electric motor 4, and between rotor 15 and stator 16, and as well as between rotor 15 and radial bearings 17, 18 there formed is gap 22 passing in a circumferential direction and along longitudinal axis 6 of shaft and filled at least partially with fluid medium. Electric motor 4 is also made as a support and connected to control 2 that controls electric motor 4 so that together with transfer of torque moments 30 for actuation of machine 1 converting the fluid medium energy there is also a possibility for application of radial forces 60 to longitudinal axis 6 of the shaft.
EFFECT: improving reliability of a machine converting the fluid medium energy.
