This invention relates to a multi-impeller-driven horizontal axis micro-wind generator, mainly comprising a novel multi-impeller-driven power generation device and a protective wind-guiding casing. Impeller groups I and II within a barrel-shaped duct form a wind-gathering drive, resulting in better wind capture and a higher generator power output. The generator rotor rotates in the forward direction while the stator windings rotate in the opposite direction, increasing the generator speed without sacrificing torque or adding a transmission. This significantly improves generator efficiency and effective power generation time under light wind conditions. The ventilation and protective cover prevents the high-speed rotating impeller from injuring birds and insects, making it more environmentally friendly. Under low-elevation installation conditions, the ventilation and protective cover isolates floating foreign objects, preventing damage to the impeller and further improving the service life and economic efficiency of the micro-wind generator. It also more effectively reduces emissions of greenhouse gases such as carbon dioxide, contributing to environmental protection and sustainable development.
