The B3 is a powerful 12 V motorsport alternator. It has an optimized hand wound stator winding (3 phase triangle), high current diodes (special Zener diode chips from Bosch production to retain load-dumps) and an extra fine balanced rotor with double impregnated winding.

The B3 LIN is a powerful 12 V motorsport alternator. It has an optimized hand wound stator winding (3 phase triangle), high current diodes (special Zener diode chips from Bosch production to retain load-dumps) and an extra fine balanced rotor with double impregnated winding.

This alternator is modified for motorsport demand and splash protected. The stator windings are handmade and optimized for higher current output; the rotor is extra fine balanced and double impregnated. The alternators are e.g. used in Nascar series. Clockwise and anticlockwise versions are possible, modifications are available on request.
