| Product name：7.5kw 150rpm axial flux permanent magnet coreless generator for wind turbine |
| Item： |
| Details： |
Our disc coreless PMG have advantage in low Rated speed, Low starting wind speed, Small volume, Energy Small, Light weight, Compact structure,High efficiency etc.
Inner or outer rotor all available,and we can do customize generator according customer request
magnetic levitation ,Coreless, anhysteresis, slotless, have low starting torque.
No iron loss, have high efficiency over 98%
Adopt unique coreless precision winding technology design precision coil
Adopt the rare earth permanent magnet, which is multipole, mean gap, high power density and high output power.
Low speed direct driving, no torque fluctuations
Compact structure, high ratio of power to volume
No iron loss, low calorific value,small temperature rise
Simple structure, easy to install
The brushless structure, free maintenance
