Highly efficient multipole generator | Blade pitch system and safety system |
Direct coupling of the multipole generator to the rotor · No gearbox required · Practical application of advanced technologies | Blade pitch system with tooth belts · Lubrication not required · Minimum play in blade drive tracks · Minimum wear · Maintenance free |
Synchronous generator with permanent magnet excitation · High efficiency, particularly at partial load · No energy losses because of an external excitation · No slip rings for external excitation needed | |
External runner concept · Compact design, small generator diameter | Double‐layer capacitor for emergency re‐pitching · No heavy lead‐gel accumulators required · Brush‐less pitch motor · Increased lifetime · Maintenance free |
Passive air‐cooling system · Highly efficient cooling without any additional energy |
