20KW 400RPM PMG Hydraulic permanent magnet generator Characteristics
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.
production features
1.The generator has many poles, which improve the frequency and efficiency, saving the cost of rectifiers and inverters.
2.Finite Element Analysis is used when designing the generator.compact structure. Low startup torque, solves the problem of small wind startup, improving the wind energy utilization.
3.Leave out the gear increaser, improve the reliability and efficiency of the generator, lower the amount of maintenance.
4.H class insulation, vacuum pressure impregnation.
5.Have many stucures such as vertical axis. horizonal axis, ineal rotor external rotor plate type.
6.Strong rotors, the generator could achieve high speed.
7.Small size, light weight, high energy density, suitable for special situations.
8.Run efficiently throughout the whole speed range, high efficient.
9.Use imported high- speed oil-contained bearings, maintenance free, high reliability, long service life
10.The parameters like voltage, speed, power can be customized. The shape can be changed. Spline shaft, biaxial extension, flange can be used.
