Abstract
Abstract Herein described is an air driven generator for providing electrical energy for charging storage batteries. A plurality of rotors including a round rim, a hub and connecting vanes are alternately interdisposed upon a fixed shaft between a plurality of corresponding hollow stators. A segmented permanent magnet is mounted around the periphery of the rim of each rotor and creates a moving magnetic field. A corresponding stationary armature is positioned on stators adjacent to a corresponding rotor and suspended around and over the corresponding rotor.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
191 words
In an air driven electrical generator for recharging batteries, said generator including: a stationary horizontally disposed shaft; a plurality of stator elements fixedly mounted to said shaft, each stator element of said plurality including a rim, a hub and webs supporting the rim to the hub, saiD rim, hub and webs defining a hollow area for the passage of an air stream therethrough; a plurality of rotor elements rotatably mounted to said shaft, to rotate independently from each other, each rotor of said plurality of rotors being interdisposed between alternate stators of said plurality of stators, each said rotor element of said plurality including a rim, a hub and vanes disposed between the hub and the rim; a plurality of arcuate magnetic segments disposed on the periphery of each rim on each rotor of said plurality; and a plurality of armature members, each armature for a corresponding one of said arcuate magnetic segments each armature being mounted to adjacent stators radially outward of the rim of corresponding rotors; whereby air passing through the stator webs causes the rotor vanes to rotate the magnetic segments past the stator armatures to generate electricity.
