Abstract
A permanent magnet electric generator includes a rotor assembly and a stator assembly. The rotor assembly has axially disposed annular outer and inner rings concentric with an axis of rotation. A plurality of magnets is disposed on the outer ring, each magnet having a north pole and a south pole. The permanent magnets are aligned with the axis of rotation, and adjacent magnets have alternating polarity. The stator assembly includes a plurality of stator blocks aligned to form an annular ring-shaped stator member retained by a stator frame. The stator member is configured to be at least partially disposed inside the rotor assembly and is circumferentially encircled by the rotor assembly.
