Product core selling point                                                                                         

The permanent magnet generator mainly uses rare earth neodymium iron boron permanent magnet to ensure the reliability and stability of magnetic power generation. In the transmission process, the direct drive method is adopted, and the gearbox is not used, which reduces the energy loss during power generation. To ensure the utilization of wind power. It has excellent heat dissipation performance and can increase the temperature of the fan to increase the service life of the product


System Solution                                                                                                         

GREEF Technical Team can provide the complete ON-grid and Off-grid solution for the project which used our permanent magnet generator . All the equipments can be produced according to customer's specific requirements
