Generator( Magnatic) Model EA-G-400 (400W)

Eawin VAWT products is R&D by our Japan company, and produced in Shanghai, which have the most advanced technology in the world.

The EAWIN generator features an outer rotor structure that allows rotation of a magnet and coreless design that eliminates an iron core. The generator achieves noise-free rotation, together with extreme smoothness. Since the generator is free of electrically contacted components, the cogging torque that impedes rotation is not generated. The rare earth magnet generates a strong magnetic field. In addition, the multipole design 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.

The generator incorporates a gear-free direct drive mechanism
The EAWIN wind power generation system produces electricity by means of gear-free direct drive mechanism. This mechanism features high-efficiency power generation, trouble-free operation, and extreme silence.

The generator ensures safe operation under strong wind conditions
The generator is so safety-designed that it can endure the continuous braking even during high-speed rotation under strong wind conditions. The pole-top bearing made of corrosion resistant aluminum alloy is designed by utilizing our unique technologies and ruggedly supports the generator shaft, providing the highest levels of safety even under strong wind conditions.

The generator has a powerful brake system
The electric(electromagnetic) brake system of a EAWIN generator permits trouble and wear-free operation even during continuous operation and thus ensures the highest safety. The brake system can safely decelerate the generator even when it is necessary to rapidly stop the generator while rotating at more than 300 rpm.
