Advantage
 1. Rare earth Nd-Fe-B permanent magnet generator. energy save energy more than 15% than ordinary generators.
2. Permanent magnet rotor structure, no excitation winding, no carbon brushes, no slip rings, no need gear box.Simple structure, reliable ,durable and Maintenance free.
3. Multi poles design, improve the frequency and efficiency of rectifiers and inverters. Saving cost .
4. Started directly, without control cabinet, replace the asynchronous motor totally.
5. H class insulation, vacuum pressure impregnation.
6. Use SKF bearings
7. Power factor close to 1,no need add power factor compensation equipment.
8. Small heat, aslo can add fan cooling or water cooling
9. Long life time >20years, Strong rotors, could run at high speed.24hours 365days running.
10. Energy-saving, return investment within 1-2years.
