No hysteresis and gear notches effect make the start torque very low <1N.M(2) Original Structure: use disc coreless motor to take place traditional motor makes it less volume and weight.(3) Higher Utilization: use special coreless motor technology to eliminate the use bottlenecks of lower speed wind energy.(4) Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.(5) Gearless, direct drive, low RPM generator.(6) High standard, quality components for use in harsh and extreme environments for wind turbines(7) High efficiency and Low mechanical resistance energy loss(8) Excellent heat dissipation due to the Aluminum alloy outer frame and special internal structure.Technical DataModelGDG-500W-400Rated Power500WRated Rotate Speed 400 RPMOption Rated Voltage 24V-220VacEfficiency>85%Wending MethodYInsulating Resistance100Mohm Min(500V DC)Leakage Level<5 maStart Torque<0.1N/MRated Torque29N.MPhase Type3 PhaseStructureOut rotorStatorCoreless wire coilRotorRare Earth Permanent MagnetGenerator Shell Diameter320mmGenerator Shell Length219mmWeight20kgShaft drameter45mmGenerator shell materialAluminum alloyShaft materialCarbon steelBearingNSK Deep groove ball bearingDrawing SamplePackaging & Shipping1.Generator use inner foam protection outer Plywooden case .Generator shaft use pipe protection.2.

Q: Does installation Easy ? A: Very easy, every customer can doing by themselves, we will supply all the components for installation and very detailed installation manual.2. Q: Does our wnd is enough for a wind generator ? A: As our wind generator can start running at low wind speed 3m/s. so your average annual wind speed is more than 5m/s then you can use it .3. Q: Which model wind generator is suitable for me? A: Plese contact our sales with following points : 1. What appliance do you want to running by the system? How many watts are they and their working time . 2. Your annual wind speed . 3. What kinds of system do you want ? On-grid or off-grid4. Q:Can I only buy parts not whole system? A: Yes,for example you can manufacture tower in local , we can suplly you tower drawing .
