1. Any permanent magnetic alternators, providing invariable excitation on all occasions.
2. Easy to be connected with power network or other alternators.
Standard 2/3 pitch windings check excessive midline current.
3. Balanced rotor with single or two sealed ball bearings.
4. Convenient installation and maintenance with easy access to terminals, rotating diodes and coupling bolts.
5. Wide range of flange adaptor and single bearing coupling disc.
6. Meet leading standards.

Output power of exciter's rotor is input to that of mains through 3-phase full wave rectifier. Two ends of the rectifier are connected with piezoresistance for restraining surge voltage and avoiding the impact is equipped with permanent magnetic steel. It can make alternator starting smoothly in any occasions.
