Polar Power first tested its DC Alternator using its Permanent Magnet Hybrid Homopolar (PMHH) technology in 1992. Since then numerous organizations have performed extensive testing on Polar’s generators, including the US Military.

Polar Power has met these performance goals through an integrated engineering effort involving detailed analysis of engine, voltage regulation electronics, field coil, magnet, stator, rotor, and diode effects on the generators output voltage, current, and electrical quality.

Polar Power selected and optimized the 6200 series alternator using our PMHH technology because it does not require brushes, slip rings, rotating fields, exciters, or field flashing. Its small and compact design allows the use of a bearing-less pancake design.
