Abstract
The invention relates to a homopolar generator for a device for generating electrical energy. The generator is, in particular, part of a wind or water power generating system and is driven directly, i.e. without intermediately connected gear mechanisms, by the blades of the wind or water power system. A superconducting coil, which is mechanically decoupled from the rotor, i.e. does not rotate along with the rotor, generates a magnetic flux which is conducted by the rotor in such a way that it penetrates the stator winding of a stator in the radial direction. For this purpose, the rotor has rotor sections which surround the stator in the form of a claw and which conduct the magnetic flux. Poles which conduct the magnetic flux and which cause the magnetic flux to vary, viewed in the circumferential direction of the stator, are provided on the rotor sections. When the magnetic field is constant and the rotor is rotating, a voltage is therefore induced in the stator windings. The rotor preferably rotates at a constant frequency. By correspondingly selecting the pole numbers it is possible to adapt the output frequency of the generator to the mains frequency.
