Abstract
A motorcompressor unit includes a first motor driving the rotation of a rotor and a compression stage including a bladed impeller mounted on a driven shaft, the rotation of which is driven by the rotor. Also, common casing is gastight with respect to fluid handled by the motorcompressor unit, where the compression stage and the first motor are mounted in the common casing. The compression stage also includes a regulating member that regulates the angle at which the fluid flows to or from the bladed impeller, and a second motor that controls the regulating member, the second motor being mounted in the common casing.
