This generator uses a unique outer rotor and core-less structure. The generator achieves noise-free rotation, together with extreme smoothness; the cogging torque that impedes rotation is not generated. The rare earth magnet generates a strong magnetic field. In addition, the multiple designs can generate high voltage even at minimum rotating speeds and realize high-power output and improved efficiency in the range from low to high wind velocities.
Gear-free direct drive mechanism
Unique reinforced structure of flange ensures wind resistant ability strong and a god resistance to corrosion
Unique reinforced structure of flange ensure wind resistant ability strong and a good resistance to corrosion
This generator uses an outer rotor structure, and the armature windings do not use the silicon steel sheet. So the generator starts without reluctance torque, which can reduce the start-up wind speed of the wind turbine
