Note: As of September 27 2009, total motors listed on EVDL is 2093. 3 of the top 10 as well as others offered by EV component suppliers listed above are shown, totalling 900 or 43%. General Electric, Kostov, Prestolite and Thrige-Titan are also popular motors making up 280 or 13%, but they are either no longer made or not readily available in the US, so they are not included above. Bosch, Unite Motors, Briggs and Stratton, Crystalite and D&D are also popular motors making up 330 or 16%, but they are smaller, best for mini cars, motorcycles or bicycles only and are not covered here.
Manufacturers known to have chargers but do not serve individuals and hence were not included above include AC Propulsion, Enova, UQM, TM4, Reliance and AC Electric Vehicles.
