However, the conventional DC brushless motor rotor structure has the following disadvantages: a large number of parts and a complicated structure: the structure of the county will be fixed by the fixed plugs placed on the stack of the Wei-shaped round hole 尔 鸠 鸠 块 与 与 与 与鸠补楔魏合' the last private plate phase gorge in the ^ Jing and tree group __ turn __, the domain process phase (7) slightly fine precision requirements · · by the county structure _ will cause assembly tolerance The big eve is also relatively improved. The precision requirements of the tree scale ants - the production process, the (3) high production cost: this conventional structure contains at least 200935709 = compared to the secret molding of the steel, the second process such as injection molding ^De and the end cover 'third__ is a wire to produce magnets, thus causing high production costs. [Invention] In this case, the present invention provides a motor rotor structure, not only the components of the evening It does not need to be too secretive to require dimensional precision, which can reduce production costs. · Ο ❹ It contains: a shaft center is a cylindrical long rod body; a plurality of magnet pieces are thin circular plates with a central Ten heart holes for shaft wear There are at least one more than one buckle groove in the periphery, the buckle groove must penetrate the circumference of the magnet buckle piece and be similar to the tail groove type inside and outside; at least two magnets are in the shape of the buckle corresponding to the magnet piece The state can be embedded and fixed therein; the two magnet slabs are in the form of a thin circular plate and are supported on the two ends of the magnet, and have a central hole in the center for the shaft to be inserted. When assembling, the magnet is first embedded After the stacked magnet buckles are fastened, the bonding between the two can be fixed by coating, or the two magnets can be used to fix the two ends of the magnet, which is not only quick and convenient to assemble, but also has no assembly. The cumulative tolerance problem is that it is difficult to strictly require dimensional touch, and the magnet clasp and the magnet cymbal of the present invention can be stamped and manufactured, and can be used to process the production process and reduce the production cost. 200935709 [Embodiment] The invention relates to a motor rotor structure, as shown in the third figure, the structure comprises: an axial center (50), which is a cylindrical long rod body; a plurality of magnet pieces (60), which are thin circular plates and guided magnetic Made of material, the center has a center hole (61), the inner hole (61) has an inner diameter approximately equal to the outer diameter of the shaft (5〇). The magnet clasp (60) has at least two or more retaining grooves around the periphery () (The four shown in the figure) 'The buckle groove (10) must penetrate the circumference of the magnet clip (6〇) and form a similar tail-slot type inside and outside, and a plane (63) inside the pin 62); / / - Viewing magnets (7〇) (four shown in the figure), the body 1's side is the flat surface corresponding to the plane (6) of the above-mentioned buckle groove (62), and the other side is the arc convex Type; 〇. (81 two iron middle cymbals (10) 'is a thin paste body' and has a center ~ The center hole (81) inner diameter is approximately equal to the fine (50) outer diameter. Its group scale 'please match with the reference The hole between the hole (6Ϊ) and the axis (9) shown in Figure 4 and Figure 5 is tightly fitted, and the magnet (10) is placed flat on the surface (turned by the magnet buckle ~ W pin, so that the magnet (Κ (4) iron buckle (10) The side is sliding along the buckle groove (10) (the shaft is ϋ autumn magnet (4) (10)) Hehe is embedded in the fixed position; C63), and the wedge shape is @200935709 Finally, two magnet spacers (80) can be added to block the magnet. (7〇) two ends, and Also form a tight fit between the iron shim (80) of the central bore (81) and the axis (5〇), can further ensure that the magnets (7〇) fixed position, not to fall off when the high-speed rotation. In addition, as shown in the sixth figure, the magnet (7〇) of the present invention is fitted and fixed to the buckle groove (62) of the magnet clasp (60), and the side of the arc convex shape must face outward, and each magnet (70) The curvature of the arc must be smaller than the outer diameter of the magnet clip, and the center of curvature must not be located at the center of the axis (5G), so that the arc curvature of each magnet (5) is not located on the same circumference, so that the magnet (7〇) The magnetic torque is small and the magnetic lines of force are concentrated. Therefore, the present invention has the following advantages compared with the conventional structure: (1) few components and simple structure: after the magnet is embedded in the stacked magnet buckle buckle groove of the invention, the following two methods can be used to firmly combine the two. One is to use the adhesive to push the magnetic 雠 EI, and the other is to use two magnets to separate the two ends of the magnet, which is easy to assemble. (2) There is no need to strictly require dimensional precision: there are few components in the invention, so there is no problem of accumulating tolerances, so it is not necessary to strictly require dimensional precision. (3) Reducing the production cost: The magnet cleat and the magnet flake of the present invention can be stamped and manufactured, thereby simplifying the production process and reducing the production cost.
