Tianlong --- Professional Permanent Magnet Generator Manufacturer 
Company official website:

100MW Yearly Production PMG Manufacturer From Rare Earth Origin
About 80% world rare earth reserves was in Baotou,which provide us with abundant permanent material.We also have a strategic cooperation with the BGM to insure good quality and reasonable cost of PMG in mass production.
Tianlong Generator have invested 50 million RMB to set a new industrial base ,with a factory and a R&D center building covering 10000 area .The yearly PMG production will increase to 100MW,and Tianlong Generator will be the largest permanent magnet generator manufacturer in China small and medium wind turbine industry.
Professional Wind Turbine Generator Manufacturer
With the Tianlong Generator range of Permanent Magnet Generator PMG's for small wind turbines based on permanent magnet technology, you will have a different experience:
Low Cogging : Based on optimum pole slot configuration , The starting torque is 40% lower than  national Standard .and could be 1% of the rated torque .
High Effiency: Based on optimum winding design ,low current density makes less copper loss, we can offer an efficiency 10% higher than national standard and can be in excess of 95%.   
Tianlong Generator offers a variety of possibilities of mechanical size, RPM, power rating etc,and The PMG can be operated with a wide range of output power.
Let us help you implementing our Permanent Magnet Generators in your small wind turbines.
Quality Guarantee
The stator and rotor of generator apply high grade cold rolling silicon sheet, with high intensity and characteristic of uneasily deformed; the stator windings are wound with 180 grade combing paintcoat series enamel-cover round copper wire, especially it is impregnated by the techniques of combing process of vacuum constant temperature and constant heat, it has elevated insulation grade .We apply high quality 40SH,42SH,40UH rare-earth NdFeB(Neodymium Iron Boron) Magnet to our generator. The fastness of magnet steel of rotor adopt inlaid type process, strong adhesives splicing ,furthermore epoxy resin encapsulating technology which increase stability and corrosion resistance of magnet. We choose professional completely-enclosed NSK,NTN,SKF,C&U bearings and nickle plated 40Cr steel shaft with quenching and tempering treatment,the outer frame  is Zinc plated  with anti-corrosion treatment.We believe high quality material and advanced craft is the firm guarantee of the high quality products.

Tianlong --- Professional Permanent Magnet Generator Manufacturer 

  Tianlong Generator offers different kinds of PMGs ranging from 50W to 1MW, with speed range from 50rpm to 3000rpm. The Tianlong PMGs can be designed with an inner or outer rotor construction. Each PMG topology is designed to best match specific usage, such as wind, hydro or any power that can drive PMGs, and meet any customized requirements. By eliminating cogging, we reduce mechanical stress, improve reliability and extend the PMGs overall lifetime. Thanks to the improved density, a PMG is compact and lightweight, leading to greater flexibility with limited space restrictions.
