This Coreless Permanent Magnet generator is ideal for vertical axis wind turbines and other generator systems requiring very low start torque, low rated rotation speed, low start wind speed, lightweight construction, and compact size.
| 1 | Torque Patent Technology: Uses newest "Precise Coil" technology. No hysteresis and gear notches effect make the start torque very low <0.1N.M |
| 2 | Original Structure: Uses disc coreless motor to replace traditional motor, resulting in reduced volume and weight |
| 3 | Higher Utilization: Uses special coreless motor technology to eliminate 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 Aluminum alloy outer frame and special internal structure |
We can provide complete generator systems including Controller and Inverter for various applications.
Generators are free 3 years warranty, All lifelong technical support and part cost supply.
