Features & Characteristics of  free energy PM generators

1. Permanent Rare Earth NdFeB Neodymium magnet generator.  Saving energy more      than 15% than ordinary generators. Get investment returned within 1-2years.

2.  Simple structure : no excitation winding, no carbon brushes, no excitation controlling-box,
no spark, no slip rings, no need gear box. --Reliable, Durable, and saving Maintenance free with   Protection level: IP54.

3,  . Small starting torque, low speed generating, improving wind energy utilization.

4. Multi poles design, improving the frequency and efficiency of rectifiers and inverters. Saving cost .

5. Starting directly, without control cabinet, replacing the asynchronous motor totally.

6. H class insulation, vacuum pressure impregnation.

7. Use SKF bearings

8. Power factor close to 1,no need add power factor compensation equipment.

9. Small heat, fan cooling or water cooling available also

10, Small size, Light Weight, High Energy Density, Suitable for special situations.

11. Long life time >20years with very high speed 24hours 365days running.

12. Custom installation methods : spline shaft, dual shafts, flange or other  installation methods.

 Application:

widely used in electric vehicles, wind/water generating systems, oil production equipments, and other speed regulation facilities.

Our Strength:  We focus on  permanent magnet generator and motors which are energy-saving, high efficient, clean, light, and low-carbon, having vast market prospect.
