Dual internal fan alternators
Dual internal fan alternators
Description
At Prestolite we consider ourselves specialists in alternators and regulator technology, with 108 years of experience.
The last decade has seen significant changes in alternator and regulator technology with dual internal fan alternators offering improved cooling better heat dissipation and increased output and a light weight compact design.
Hairpin stator technology is back.
Hairpin stators with rectangular profiled copper bars (hairpins), similar to that found on starter armature design, allows for maximum gap fill, where as traditional copper wire could not fill the slots in the laminations, leaving air gaps.
The use of hairpin stators yield a 50% increase in output vs the same size conventional coil wound stator (AVI147 vs AVI150) or in terms of alternator weight, up to 60% reduction.
