  • GDG-10KW 100RPM



The magnetic generators are always being used in vertical axis wind turbine generator, diesel gasoline generator ,hydroelectric generator(water-power generator) and other generator system which requests very low start torque and low RPM.



Magnetic Generator Overview


The coreless disk permanent magenetic generator is made of high-stability Nd-Fe-B materials.


The specific outer rotor magnetic circuit is designed in a special way. The magnetic generator


has following features:


Low starting torque, Low start wind speed, Low weight,small size ,High generating efficiency



  Magnetic Generator Features


  • Torque Patent Technology: use newest “Precise Coil” technology. No hysteresis and gear notches effect make the start torque very low <1N.M
  • Original Structure: use disc coreless motor to take place traditional motor makes it less volume and weight.
  •  Higher Utilization: use special coreless motor technology to eliminate the use bottlenecks of lower speed wind energy.
  •  Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.
  • Gearless, direct drive, low RPM generator.
  •  High standard, quality components for use in harsh and extreme environments for wind turbines
  • High efficiency and Low mechanical resistance energy loss.
  • Excellent heat dissipation due to the Aluminum alloy outer frame and special internal structure.

Company Information








1.  Q:  Does installation Easy ?

      A:    Very easy, every customer can doing by themselves, we will supply all the components for installation and very detailed installation manual.


2.  Q: Does our wnd is enough for a wind generator ?

      A: As our wind generator can start running at low wind speed 3m/s. so your average annual wind speed is more than 5m/s then you can use it .


3.  Q: Which model wind generator is suitable for me?

     A: Plese contact our sales with following points :

        1. What appliance do you want to running by the system?  How many watts are they and their working time .

        2. Your annual wind speed .

        3. What kinds of system do you want ? On-grid or  off-grid


4.  Q:Can I only buy parts not whole system?

    A: Yes,for example you can manufacture tower in local , we can suplly you tower drawing .
