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.
