Customer Reviews
greef team is the best! i love them, they give professional and timely after-service. because of my unprofessional operation, the generator went wrong, but greef team helped me to solve this issue very patiently, the generator is good now, thanks again.

—— Jeam Mareie from Canada

¡Perfecto! Ayer, recibí este generador en Bogotá, muy buen generador. ¡Gracias

—— Stephen Brinker from Colombia

I ordered 10kW 100RPM model at the year of 2017, i ordered 1kW 180rpm this year, the disc generator has small torque,it is easy to rotate,thanks Greef new energy, I hope to do more buisness with more cheaper price on the year of 2019.

The magnetic generators are always being used in vertical axis wind turbine 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

3kW Low RPM Axial flux coreless permanent magnet generator for vertical wind turbine

 


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.
