Abstract
High torque and low rpm characterize in-stream wind and hydro turbines.
To obtain acceptable efficiencies, conventional generators require step-up gearboxes from low rpm turbines. Gearboxes are expensive, unreliable, high maintenance, and inefficient. Although generators are available that allow direct coupling to low rpm turbines, the generator's power is directly proportional to its torque handling capability and rpm. Higher torque handling capability increases generator size, weight and cost. Higher rpm allows a given size generator to produce more power; in particular, doubling the rpm doubles the generator output power and also improves efficiency. This invention is related to a turbine with two rotating components, one coupled to the rotor and the other coupled to the stator of a generator such that the rotor and stator turn in opposite directions.
This counter-rotation increases the effective rpm applied to the generator and proportionately increases the power output of the generator.
