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.
