Product Description

Product Description

20KW PMG Hydraulic permanent magnet generatorCharacteristics

1. Optimum aerodynamic shape design: high efficiency, low noise.

2. Centrifugal pitch controlled mechanism: 3m/s low wind speed startup; 3-12m/s wind speed, following wind rotor rotate speed to adjust blade angle at optimum TSR, run in high efficiency; over rated wind speed, wind rotor never goes to over speed and has stable control; 3-35m/s wind speed, wind turbine can run smoothly.

3. Direct drive permanent magnet generator, low startup resistance moment, constant running ability of over loading 1.5 times, maintenance free for more than 30000 hour. 

4. Safety control: has aerodynamic brake, electric magnet brake, mechanical brake and manual stop mechanism.

5. Sealed slip ring, no cable twist;

6. Streamline design. 

7. Long acting anticorrosive treats, no corrosion in 15years.
