Abstract: (1) This invention is a methodology invention, in which the natural physical law of magnetic repulsion (either positive repulsion or negative repulsion) is utilized as power to drive a magnet-driven motor (the magnet material used in the present invention is permanent strong magnet piece). (2) First, a main motor rotor is made by using aluminum material which can cover and block all opposite poles (positive poles) of the strong magnet, and the exterior of the main motor rotator has eight convex slots (and there are concave slots in the convex slots) for being embedded with eight driven magnet pieces each having a rectangular negative pole that faces upward. Alternatively, a main motor rotor is made by using iron material, and the exterior of the main motor rotator has eight convex slots (and there are concave slots in the convex slots). Then, a thin aluminum piece capable of covering and blocking all opposite poles (positive poles) of the strong magnet is used to enclose the overall rotator, and aluminum material capable of covering and blocking all opposite poles (positive poles) of the strong magnet is used to manufacture eight device boxes for receiving the driven magnet pieces, which are combined to form a drawer type device box for receiving eight driven magnet pieces (the driven magnet pieces are embedded in the box). Furthermore, the eight driven magnetic pieces are embedded in the box, and then they are pressed into the convex slots of the main motor rotor (including the concave slots in the convex slots) for being tightly coupled together. (3) An axle and a bearing are embedded in a through hole of the rotator, and subsequently the aluminum material capable of covering and blocking the opposite poles (positive poles) of the strong magnet is used to manufacture a fan main motor rotator housing in which a convex slot is defined at 45 degrees (there is a drawer type track in the slot). First, aluminum material capable of covering and blocking all opposite poles (positive poles) of the strong magnet is used to manufacture a device box for receiving the driven magnet pieces (the driven magnet pieces are embedded in the box), which are then embedded therein from the drawer type track in the convex slot of the rotator housing (the drawer type track is provided for adjusting the wind velocity). (4) An outermost housing formed by two semicircular motor main body rotator housings A and B is made by using plastics material, and the semicircular housing A is aligned with a 3-centimeter gap between the driving magnet piece and the driven magnet piece at 45 degrees, wherein there are two round rod insertion holes A and B. The hole A is inserted with the aluminum piece locked in the 3-centimeter gap between the driving magnet piece and the driven magnet piece connected to a two-segment pushbutton telescopic rod for use as a switch of the magnet-driven motor. In use, the two-segment pushbutton is pressed to pull up the aluminum piece of the connection rod, and then the driving magnet piece immediately induces the driven magnet piece to enable the magnet-driven motor to operate, so that the fan blades are rotated clockwise. To stop usage, the two-segment pushbutton is pressed to push down the connection rod, so that the aluminum piece that blocks and separates the magnets of the same magnetic pole in two slots is returned to its original position, thereby terminating the operation of the magnet-driven motor. The hole B is inserted with a three-segment pushbutton telescopic rod connected and locked to the driving magnet piece in the convex slot of the rotator housing for use as a control switch to adjust the distance to the driven magnet piece in the convex slot of the rotator. In use, a rod B is configured to a low wind velocity and the three-segment pushbutton is pressed down for one segment, so that the wind velocity becomes middle velocity. This middle wind velocity becomes high velocity when the three-segment pushbutton is further pressed down for one more segment. On the contrary, if it is desired to decrease the wind velocity, the rod B configured to a high wind velocity is pulled up for one segment and the wind velocity immediately becomes middle velocity. This middle wind velocity becomes low velocity when the three-segment pushbutton is further pulled up for one more segment.
