The original bucket generator used an expensive General Motors based permanent magnet alternator (PMA) built in the States. The new generators built for Abra Malaga Peru use the Toyota based PMA developed be Sam Redfield in Guatemala. The Nippondenso alternator that we now use is perhaps the most common alternator in use worldwide and can be converted locally in developing countries to a PMA using the permanent magnet rotor shown above. See how it’s made in the Build Manual section of this site, or click on the link below to go directly to the build manual.
