<p>This invention relates to a screw‑type positive displacement machine (1) comprising a housing (2) with a first rotor (3') and a second rotor (3'') which are mounted to rotate in the housing (2) and which are driven in directions which are the opposite of one another, the positive displacement machine (1) comprising a first motor (4') and a second motor (4'') which are arranged in a drive casing (5) and which are connected to the housing (2) in such a way that the first rotor (3') is driven by the first motor (4') and the second rotor (3'') is driven by the second motor (4''). Typically, the first motor (4') and/or the second motor (4'') is an asynchronous motor.</p> |
