4kw 550 rpm 84v DC Permanent Magnet Generator

A popular one kilowatt turbine with a better warranty will generate 77 watts with a 3.6 m/s wind speed. That gives 675 kWh each year, reducing the customer's annual electric bill by $81. The turbine sells for $4400 without the tower, and this turbine is much heavier, so it requires a stronger tower.Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.
