Description

Technical Field

[0002] A micro wind turbine is a wind turbine with a generating capacity of 10 kilowatts or less. Its basic working principle is to use wind power to rotate the blades, thereby rotating the generator and generating electricity. When the wind blows through the blades, the blades are pushed by the wind and begin to rotate. The rotating blades will drive the rotor in the generator to rotate. The rotor is usually composed of magnets and will generate a magnetic field. The magnetic field passes through the coil, causing electrons to flow, thereby generating current, which is electricity. The micro wind turbine is mainly composed of a wind wheel, a generator, a rotating body, a speed control mechanism, a direction adjustment mechanism, a brake mechanism and a tower. It has the advantages of simple structure, easy use, environmental protection and energy saving.
