PLEASE NOTE THAT THIS ALTERNATOR IS NO LONGER AVAILABLE FOR SALE. CHARLES HAS DECIDED TO USE IT, AFTER ALL. (Hugh, January 2014)
Charles Haynes has built a large ferrite alternator for a project that no longer needs it. The alternator can produce 3kW at 75 rpm with 90% efficiency. He is looking for a home for it. It’s pretty heavy though! At present it is in Vancouver, Canada.
