Abstract
The permanent magnet electric generator includes a plurality of ferromagnetic bars disposed in spaced apart relation about the circumference of a non-magnetic, annular rotor body circumferentially surrounded by an even plurality of stator rows uniformly distributed around and arranged normal to the rotor. Each row of stators has a plurality of interconnected stators, each stator having a nonconductive innermost core surrounded by ferromagnetic material and successive layers of insulation, windings of conductive wire, and layers of ferromagnetic material circumferentially surrounding the underlying layers in a pre-determined repeating pattern.
