New description: [New technical field] This is a kind of motor rotor, especially the inner rotor structure with permanent magnet on the motor mandrel, which can effectively solve the resonance of the conventional rotor due to rigid joint. The problem of noise. [Prior Art] Motors (motors) are mainly capable of converting electrical energy into mechanical energy, which in turn drives mechanical actuation. Therefore, it is widely used in various electrical appliances that are often in contact with everyday life. Its applications are more widely used in the semiconductor industry, automation industry and instrument industry. Wait. The working principle of the motor basically uses the coil on the stator to excite the permanent magnet on the rotor in an electronic commutation manner, thereby driving the rotor to rotate at a high speed, and then driving the rotating power through the mandrel of the rotor to drive For example fan blades or other mechanical components. The structure of the above rotor is different according to the way of using the motor. The internal design is divided into two types: the outer rotor and the inner rotor. These two structures have their own advantages and disadvantages. The present invention is only for the internal rotor structure. As shown in the first figure, it is a commonly used inner rotor structure. The motor rotor is mainly provided with an annular permanent magnet 2 *** on the periphery of the motor mandrel 10, wherein the motor anger axis 10 and the permanent magnet 20 Between the two, the mold is directly fixed by gluing or fitting, that is, the motor anger shaft 10 and the permanent magnet 20 are rigidly combined. This rigid combination of conventional rotor construction is driven by the material, because of the horse: the other rotation of the M307244, the bowing stone 2 ^ paramagnetic action, in the high-speed rotation and permanent magnet 2 〇 _, tolerance m When the shaft resonance phenomenon is transmitted to the tea taking piece or other mechanical components through the motor mandrel 1 Q, in addition to the feather, the vibration of the two pieces of the sealed object during operation is also quite large, and the defensive _ Scale (10) makes a turn, [new content]; this creation is to set a = set between the motor mandrel and the permanent magnet, with the _ 峨 _ _ with the permanent loser, the motor: from the fortune Magnet _, #永纽石目激磁伽崎 axis high-speed rotation 1 elastic lining to read the secret and permanent magnet _ resonance, lying so that the motor rotor _ moving wind money other foreign counts recorded high, when it is not easy to produce and嗓音问通's large-scale feeding to the rotor's transfer rate and service life. When the J-foil bushing is in Besch, it should be made up of two symmetrical elastic bodies. The center of the elastic body is provided with a shaft hole fixed by one side of the common motor mandrel, and the outer edge is as long as the water. _ 咖定, domain t permanent magnet (4) When pumping at high speed, the elastic bushing can absorb the resonance of the mandrel and the permanent magnet for the purpose of smoothing. In addition, the motor mandrel and the elastic bushing are fixed in such a manner that the outer core of the motor core shaft is pre-baked and the outer edge of the shaft hole is provided, and the elastic bushing is provided with a corresponding concave surface at the periphery of the shaft hole. The mouth is such that the motor mandrel and the elastic bushing are fixed by the fin insertion recess. = Fixed between the permanent magnet and the elastic bushing, which can be placed in the permanent magnet.卩' and the elastic sleeve is provided with a corresponding groove on the outer edge, so that the permanent magnet "ball" is fixed between the raw bushes by the convex portion embedded in the groove. Furthermore, the outer edge of the motor mandrel is convex. The fin piece can be directly formed into 1 by the plastic injection technology and the convex part of the gj in the permanent magnet can be formed in the process of permanent magnet manufacturing, #punching and sintering, and has the advantages of precise structure and stability. The preferred embodiments of the drawings, component symbols, and detailed descriptions of the accompanying drawings are as follows: As shown in the second to third figures, the motor rotor of the present invention is on the motor spindle/ Between the inner circumference of the magnet 2 Q, the 'at least the elastic bushing 3' is indirectly coupled to the permanent magnet 20 by the elastic bushing 30, and the permanent magnet 2 (10) is excited to drive the motor. When the core W 旋转 rotates at a high speed, the clear bushing (10) can absorb the motor mandrel! 〇 Resonance with the permanent magnet 2 〇, and thus the fan or other external device (not shown) for motor rotation is not easy to generate when rotating at high speed. Vibration and *(3) questions '大缺升骑轩Axis efficiency and manufacturing life. x In the specific implementation, the elastic bushing 30 in the present invention is formed by the two figures symmetrical elastic body 3, as shown in the third figure and the fourth figure. The corresponding body 31 is provided with a shaft hole w L for the motor core shaft passing through its center, and its outer edge is fixed with the inner circumference of the permanent magnet 20, so that when the permanent magnet 2 〇 drives the horse 7 M307244 to the core shaft speed When rotating, the elastomer 3 l gp can absorb the mandrel vibration, which achieves the purpose of the foregoing. In the common illustration, the elastic body 31 of the elastic bushing 30 and the motor type can be in the shaft hole 311 of the elastic body 31. The peripheral edge is provided with a plurality of notch square motor core shafts 1 则 is provided with corresponding flaps 丄丄, when the elastic core reaches the periphery of the core (4), the motor is finely finished to terminate the two elastic bodies 31 and the corresponding rotation 'I,,... by 1 〇 wing sheet 1 1 can be realized by plastic injection molding technology, which has the advantages of precise structure and stability. / Injection into the fixing method between permanent magnet 20 and elastic bushing 30 The outer edge of the corresponding elastic body 3 1 is provided with a plurality of grooves 3 i 3, and the permanent magnetic enclosure is provided For the detail 21, _21 sets the inner magnet 2 G and the two elastic bodies 3 i in the manner of holding the water to rotate correspondingly, and then 1, 2 〇 and the elastic bushing 30. The connection between the magnet 2〇 and the elastic bushing 30 is also the 'relationship between the two corresponding elastic 〇舆 of the elastic bushing 3() (4), and (4) the connection relationship of the office === 0; 0 is tightly coupled with the elastic _3 ,, and the concave = up to the mandrel 1 permanent magnet 20 is held, so that the elastic body Ί Ί = 1 3 test _ bushing 3 〇 and then the role of the undisplaced important 1 yuan into the axis The core 1〇 and the permanent magnet 20 are not in the middle of the 'Bricking 3', and the other is included in the elastic body U, the lower 8 M3 07244, the mouth 3 2 '杂©定# 3 2 and the pair have provided The perforation 3 3 penetrated by the insertion end 3 4, through the same position of the insertion end 3 and the manner of the elastic body 31, the two elastic bodies 31 are tightly spotted, and the entire set of elastic bushings 3 complete the horse i 〇 and perpetual: 2:: 吏 This limitation of the creation 'for example: the above permanent magnet 2 〇 inner garden: 1 := In the water for a long time magnet 2 (four) made a fortune, depending on the sintering - body 2 creation application Wai, Be careful.
