The Thermax TC25G

         The Thermax TC25G low-rpm, permanent-magnet generator was originally designed for the Helius Rotor Kit - a wind power generating system that would become a core product for Thermax Corporation. Its nominal power rating was 25 watts, but could put out up to 150 watts at 3000 rpm. It came with a 5/16" shaft, bronze bushings, and 2 end-mount bolts. The internal brushes were not field-replaceable. Before the Internet, sales were direct to the user by way of ads in magazines like Popular Mechanics.
