5000W 5kw 100rpm Low Rpm Low Torque Low Weight Coreless Permanent Magnet Wind Generator, Axial Flux Coreless Generator

Product Description

wind energy generator for vertical axis wind turbine

Product Description

GreeF company supply variety of permaent magent generators which is suitable for driven by following equipment to  

1. Driven by Wind Power --------Wind turbine
2. Driven by Hydro Power ------- Water turbine, Tidal, Ocean power
3. Dirven by test plant 
4. Driven the permanent magnet generator and make it rotate then it can generate power 

 

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 NSK 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.
