Abstract
A rotary machine having two meshing rotors (14,15) rotatable in intersecting bores (12,13). The bore walls are provided with a number of electrical windings (18,19) being stator windings of an electric motor in which the pump rotors (14,15) are the rotors of the electric motor. The electrical windings are connected to an inverter which creates rotating magnetic fields which rotate the rotors.
