Patent ID: 8461703

Claim:
An engine-generator comprising: a rotary engine having a housing formed with an aperture on a central axis; an output crankshaft having an end portion extending through the aperture with said crankshaft and said housing being mounted for rotation with respect to each other; a generator having a stator secured to said end portion of said crankshaft; a plurality of magnets secured to said housing at a radial distance from the central axis with each magnet having a first pole face lying in a first plane orthogonal to the central axis; and a plurality of windings affixed to said stator at a radial distance from the central axis, each of said windings having a corresponding second pole face lying in a second plane orthogonal with the central axis and being spaced from and confronting the first plane with said first and second poles being rotatable with respect to each other for periodically aligning in a confronting relationship to define an air-gap therebetween said windings for producing an electrical output in response to rotation of the said magnets relative to said windings.
