Large diameter turbogenerator for generating electrical energy at high power

摘要

A large diameter turbogenerator for generating electrical energy at high power, using a ring generator which is integrated on the circumference of the turbine wheel, is equipped (as an internal pole or external pole rotor) with highly energetic permanent magnets in the rotor and is incorporated in a load-bearing part. The stator and rotor of the ring generator are arranged in the load-bearing part and in the turbine wheel respectively and, according to the invention, each in addition has a plurality of bearing magnets. The bearing magnets which are arranged in the stator and the bearing magnets which are arranged in the rotor are designed in such a manner and are repelled from one another in such a manner that the propulsion forces are greater than the radial attraction forces between the stator and rotor, and in such a manner that a magnetic gap of constant width is maintained between the stator and rotor during operation.
