10kw Axial Flux Permanent Magnet Generator Low Rpm For Vertical Axis Wind Turbine
GreeF company supply modified kinds of Coreless Disk Permanent Magnet Generator main model as follow:
GDG-500W 120RPM
GDG-1KW 120RPM
GDG-2KW 180 RPM
GDG-3KW 100RPM
GDG-3KW 160RPM
GDG-5KW 100RPM
GDG-10KW 100RPM
They are always being used in vertical axis wind turbine, and other generator system which requests very low start torque and low RPM.
Advantage
GREEF DDG series generator have following features:
Low rated rotate speed, Low start wind speed, Low weight and small size, High efficiency
(1) Torque Patent Technology: use newest “Precise Coil” technology. 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.
