This Coreless Permanent Magnet Generator is specifically designed for vertical axis wind turbines and other generator systems requiring very low start torque, low rated rotate speed, low start wind speed, low weight, and small size.
| 1 | Torque Patent Technology: Uses newest "Precise Coil" technology. No hysteresis and gear notches effect make the start torque very low <0.5N.M |
| 2 | Original Structure: Uses disc coreless motor to replace traditional motor, resulting in less volume and weight |
| 3 | Higher Utilization: Uses special coreless motor technology to eliminate the use bottlenecks of lower speed wind energy |
| 4 | Higher Reliability: Special structure provides bigger ratio of power to volume, power to weight and has long life of 8 times longer than traditional motor |
| 5 | Gearless, direct drive, low RPM generator |
| 6 | High standard, quality components for use in harsh and extreme environments for wind turbines |
| 7 | High efficiency and Low mechanical resistance energy loss |
| 8 | Excellent heat dissipation due to the Aluminum alloy outer frame and special internal structure |
We can also provide complete generator systems including Controller and Inverter:
Every buyer is very satisfied with our products, shipment and service, giving us full 5 stars!
Generators are free 3 years warranty, All lifelong technical support and part cost supply.
