Embodiment
As shown in Figures 1 to 4, wind magnetic generator of the present utility model comprises: casing 2, generator 13, rotating shaft 11, cylinder 6, impeller 8, cover 1, left bearing 3 and right bearing 7.Casing 2 is divided into working chamber 15 and inlet chamber 10, rotating shaft 11 is supported in casing 2 by left bearing 3 and right bearing 7, the inlet chamber 10 that casing 2 is stretched out in one end of rotating shaft 11 is connected with generator 13 by shaft coupling 12, and cover 1 is fixed on the casing 2 of the other end of rotating shaft 11.
The rotating shaft 11 of working chamber 15 is fixed with cylinder 6, cylinder 6 is embedded with the cylinder magnetic stripe 4 of three distributions of the even circumferential along cylinder 6, the outer surface of cylinder magnetic stripe 4 flushes with the outer surface of cylinder 6, each cylinder magnetic stripe 4 is around cylinder 6 excircle 180 °, namely cylinder magnetic stripe 4 one end differs 180 ° with cylinder magnetic stripe 4 other end in cylinder 6 position circumferentially in cylinder 6 position circumferentially, three cylinder magnetic stripes 4 are identical cylinder 6 turning to circumferentially, and they can turn clockwise around cylinder 6 circumference simultaneously or be rotated counterclockwise around cylinder 6 circumference simultaneously.The casing 2 of working chamber 15 is embedded with three straight magnetic stripes 5 along the distribution of casing 2 inwall even circumferential, the outer surface of straight magnetic stripe 5 flushes with the inner wall surface of casing 2, straight magnetic stripe 5 is parallel to the center line of casing 2, straight magnetic stripe 5 is same with the Magnetic Phase of cylinder magnetic stripe 4, namely straight magnetic stripe 5 is all N pole with cylinder magnetic stripe 4 or is all S pole, the width of straight magnetic stripe 5 is identical with the width of cylinder magnetic stripe 4, and the length of straight magnetic stripe 5 is identical with the longitudinal length of cylinder magnetic stripe 4 on cylinder 6 excircle.Straight magnetic stripe 5 is not less than 9000 Gausses with the magnetic flux density of cylinder magnetic stripe 4.Have an eccentric throw between the center line of cylinder 6 and the center line of casing 2, this eccentric throw casing 2 internal diameter and cylinder 6 external diameter difference 1/12 to 1/4 scope in, such as: this eccentric throw is 1/6 of the difference of casing 2 internal diameter and cylinder 6 external diameter.
