Gearless Direct Drive Coreless Permanent Magnet Generator with Low Start Torque <0.1N.M and Above 85% Efficiency

 

Achieving near-zero transmission loss, this gearless direct coreless permanent magnet generator eliminates every source of mechanical inefficiency between the turbine rotor and electrical output. The result: more watts from every gust of wind.

• Gearless Direct Drive: Rotor directly coupled to generator — no intermediate gears to absorb power
• No Drive Train Losses: Eliminates the 5-15% mechanical loss typical of geared and belted systems
• Coreless Stator: Zero iron core losses (no eddy currents, no hysteresis losses)
• Precision Small Air Gap: Minimizes magnetic flux leakage for maximum energy transfer
• Low Start Torque <0.1N.M: No breakaway friction — power generation begins at the lowest possible wind speed

• Rare earth NdFeB multi-pole rotor for maximum magnetic flux density
• Aluminum alloy outer frame for excellent thermal management
• 8x longer lifespan with maintenance-free brushless operation
• Higher wind energy utilization in all wind speed ranges
• Compact axial flux disc design for easy turbine integration
