Abstract

PURPOSE:To enable noise and vibration to be reduced in a device simplified in its constitution by forming one of the male and female screw rotors by a permanent magnet and the other by an electromagnet respectively, directly connecting motors to each rotor, controlling one of the motors and synchronizing rotation of both the rotors. CONSTITUTION:Forming a male rotor 2 by a permanent magnet and a female rotor 1 by an electromagnet, the male and female rotors 2, 1 are housed rotatably in a casing 4. An electromagnetic coil 11 is provided in a rotor shaft part of the female rotor 1, and this rotor shaft part, in its side (delivery side) opposite to the electromagnetic coil, directly connects a motor 31 through a coupling 6. While the male rotor 2, in the suction side in its rotor shaft, directly connects a motor 3-2 through a coupling 6. By conducting an electric current to flow in the electromagnetic coil 11 through a slip ring 10, each rotor 2, 1 alternately generates N and S poles giving repulsive force between the rotors 2, 1, further the one side motor 3-1 is controlled in such a manner as synchronizing rotation of both the rotors 2, 1.
