Mechman S Series Alternators

The S series family of alternators offers large case alternator performance in a compact package. Highly efficient, these 6 phase alternators use less horsepower per Kilowatt than conventional 3 phase alternators. 12 press fit diodes, twin rectifier plates, and highly efficient twin internal cooling fans make them durable in any application. Smaller, lighter rotors and reduced rotating resistance make them an excellent choice for high RPM or racing applications. Like their big brothers in the Elite series, the S series have hairpin stators and high pole count rotors that create much less Electromagnetic noise than conventional 3 phase alternators.
