Drag responsive regulated voltage power generation

摘要

Means are provided for the generation of electricity from moving fluids. More particularly, generators of the type adapted for extraction of power from moving fluids comprising blade means mounted on a rotatable shaft, coil means mounted on said shaft, and field means separated from said coil means by a spatial gap are improved by mounting said shaft slidably with respect to said field means and by providing resilient means for maintaining said gap at a minimum value whereby the shaft may be caused to move axially in response to drag between said moving fluid and said blade means whereby the value of said gap is varied in response to said drag resulting in a regulated voltage.
