Permanent magnet generator driven by wind power

The invention discloses a permanent magnet generator driven by wind power, which is provided with a generator shell, a movable shaft penetrates through an inner bearing of the generator shell, and a protective cover sleeves the outer side of a driving blade; comprising an air delivery pipe, one end of the air delivery pipe is fixedly connected with the bottom of the protective cover, and the other end of the air delivery pipe is connected with an air collecting cover; one end of the exhaust pipe is fixedly connected with the top of the protective cover, and a reciprocating lead screw movably penetrates through the side face of the exhaust pipe; and the supporting plate is fixed to the inner top face of the generator shell, and a movable block is movably arranged on the side face of the supporting plate. According to the permanent magnet generator driven by the wind power, when the permanent magnet generator is driven by the wind power, the wind power can be adjusted, so that the rotating speed of a rotating s
