Our 6 phase hairpin alternators are significantly more efficient than conventional alternators. They’re built with hairpin stators which provide remarkable output at low engine RPM and achieve full output at 1800 RPMs. We use dual rectifier plates with high amp diodes which dissipates heat more efficiently, high amp rotors for a wider output curve, and premium bearings that allow rotor speeds in excess of 20,000 RPMs. Hairpin alternators operate at much cooler temperatures for superior durability and longevity. As seen in our bench test videos below, each alternator exceeds its ratings, operating with superior technology.
