TURBINE GENERATOR

摘要

The invention relates to the generation of electricity from flowing fluid and in the preferred embodiment to a horizontal axis turbine and generator assembly. The present invention is applicable to water turbines and the invention is described in relation to this application. It is however to be appreciated that it is applicable to wind turbines. The present invention provides turbine generator for generating electrical power from flowing fluid comprising a rotatable hub having an external surface and a rotational axis arranged, in use, parallel to the direction of the flow, a plurality of blades mounted on the external surface of the hub and extending radially outwards from the hub; a plurality of magnets mounted on a surface inside the rotatable hub said surface arranged to rotate with the rotatable hub thereby forming a rotor of an electrical generator, and a plurality of non-rotating coils fixed to a stationary cylindrical core within the periphery of the rotatable hub, said coils and core thereby forming a stator of the electrical generator.

1. A turbine generator for generating electrical power from flowing fluid comprising:
a rotatable hub having an external surface and a rotational axis arranged, in use, parallel to the direction of the flow; a plurality of blades mounted on the external surface of the hub and extending radially outwards from the hub; a plurality of magnets mounted on a surface inside the rotatable hub, said surface arranged to rotate with the rotatable hub thereby forming a rotor of an electrical generator; and a plurality of non-rotating coils fixed to a stationary cylindrical core within the periphery of the rotatable hub, said coils and core thereby forming a stator of the electrical generator, wherein the plurality of coils are connected to form multiple separate groups of coils to provide an m-phase output, and wherein the plurality of coils are further connected to form a plurality of separate isolated sets of said multiple groups of coils so as to provide a corresponding plurality of m-phase outputs.
