ENERGY CONVERTER FOR FLOWING FLUIDS AND GASES

摘要

The invention relates to an electrical machine, e.g. water turbine or bow propeller. It comprises a ring shaped stator ring and inside it a rotatable rotor ring with to it mounted blades flown around by the fluid. Magnetic means generate axial directed magnetic forces between rotor and stator. Stabilising means keep the rotor during operation in an axial stable position. According to the invention the magnetic means comprise permanent magnets to generate an axially directed magnetic preload which opposes the forces exerted on the rotor by the fluid. The magnetic means comprise the stator and rotor of the generator/motor, wherein the stator follows the rotor, relative to the axial direction.
