Power generator for a hydro turbine |
摘要 |
A power generator for a hydro turbine is axially coupled to the hydro turbine. The generator comprises a rotor arranged to rotate about an axis in response to fluid flow through said turbine. A first stator structure incorporates at least a first winding disposed circumferentially around the axis and axially displaced in a first inboard direction from the rotor. A second stator structure incorporates a least a second winding disposed circumferentially around the axis and axially displaced in a second outboard direction from the rotor, the rotor being arranged to electrically couple with the windings. |

1. A power generator for a hydro turbine, the power generator being axially coupled to the hydro turbine and comprising a rotor arranged to rotate about an axis in response to fluid flow through said turbine, a first stator structure incorporating a first winding disposed circumferentially around the axis and axially displaced in a first inboard direction from the rotor, and a second stator structure incorporating a second winding disposed circumferentially around the axis and axially displaced in a second outboard direction from the rotor, the rotor being arranged to electrically couple with the windings, wherein each of said first and second windings is a single phase winding, each of said first and second stators comprising a plurality of laminates having a plurality of slots for accommodating said first and second windings respectively, and wherein the respective slots of each of said first and second stators are non-uniformly spaced apart with the spacing between successive slots being progressively increased and then progressively decreased to create an approximately sinusoidal distribution of said slots. |
