Abstract
A wind-driven electricity generation device includes a stator assembly and a rotor assembly. The stator assembly includes a case and a magnetically permeable module disposed on the case. The rotor assembly is rotatably arranged in the case and includes a rotating member and a magnetic module disposed on the rotating member. The rotating member has a column and a spiral blade. A gap is formed between the spiral blade and the case. The spiral blade is connected to the column at a helix angle of 21˜55 degrees. The spiral blade is configured to rotate the rotor assembly with respect to the stator assembly by utilizing wind, such that an induced current is generated by the cooperation of the magnetically permeable module and the magnetic module.
