New description: [New technical field] This invention is a motor-shock structure, especially a motor structure that can be easily assembled and effectively reduced in vibration and noise. [Prior Art] The drive motor M of the conventional common fan is divided into an inner rotor (as shown in Fig. i) and an outer rotor (as shown in Fig. 2) according to the position of the rotor M1 and the stator M2. The motor system has a permanent hybrid M1 set in the stator M2 wound with an induction coil, and the outer rotor motor is rotated outside the stator M2 around which the induction coil is wound (as shown in Fig. 2). Regardless of the former rotor or the outer rotor Ma Lai, in fact, the Ml sub-running day will almost always produce noise and silk. After research, it is found that the main cause of noise and vibration is the township, and the motor structure of the motor is discussed. Most of the rotor cymbal or other motor components assembly tolerances are not properly controlled, resulting in the rotor 扪 easy to eccentrically rotate and cause balance misalignment. According to the electromagnetic field, the rotor M1 and the stator M2 will generate harmonics due to the alternating magnetic field during the actual operation. When the spectrum wave easily resonates with the motor structure, an annoying high-frequency electromagnetic sound will be generated at the same time. The higher the rotor w is, the higher the frequency of the electromagnetic sound and its loudness. No matter the noise caused by the structure of the motor or the problem of electromagnetic field, it is long-term in the fresh ring, which will affect people's riding, and also people's hearing, especially in the quiet room of technology 1. Quiet The electromagnetic sound generated by the motor is more harsh and seriously affects the operation. To this end, how to effectively improve the electromagnetic sound generated when the outer rotor motor rotates and the resonance noise generated by the motor structure are the subjects studied by the author. [New content] The main purpose of this creation is to provide a motor noise suppression structure, which uses the buffer structure and the magnetic field to repel her concept to solve the vibration and vibration problems generated when the motor rotates. The structure includes: , an inner stator, An induction coil is wound around the outer rotor; the outer rotor is sheathed to the inner stator; and the %-shaped magnet is formed by staggering a plurality of sets of magnetic phase-matching magnets. The main feature of the present invention is that the inner side of the outer rotor cylinder At least one conductive magnetic composite body is disposed between the wall surface and the outer wall surface of the toroidal magnet, and the composite system is formed by mixing the rubber material and the surface particle, and the magnetic fluid particles in the composite body are subjected to the magnetic field of the ring=stone The shadow_connected-magnetic column generates magnetic lines of force; when the outer rotor cylinder rotates, the magnetic fluid particles will not oscillate in the magnetic pole of the magnet, and the outer rotor dragon is effectively absorbed. The surface produces a dynamic effect of *_ damping and suppression. According to the above main features, the rubber material used in the conductive magnetic greening can be used as the outer rotor cylinder and the ring in addition to the friction between the outer rotor cylinder and the annular magnet. The barrier between the magnets effectively prevents the two metal bodies from generating high-frequency metal arpeggios due to operational collision, effectively reducing the spectral wave M408191. According to the above main features, the conductive magnetic composite body is further injected into a multi-brand fineness. Each of the elastic __ is against the opposite wall of the outer rotor cylinder thief-shaped magnet.

Figure 3 is a three-dimensional exploded view of the motor noise suppression structure. Fig. 4 is a schematic cross-sectional view showing the noise suppression structure of the motor, showing that the structure is mounted on the outer rotor motor. The motor (four) structure is provided as follows: the motor comprises at least: - an induction wire _ inner stator 1G, an outer rotor cylinder 2 〇 and a toroidal magnet 30 (as shown in Fig. 3); The ring magnet (4) is arranged in the outer rotor Lin 20 _ wall society, the ring magnet 3q axis sets a plurality of sets of magnets arranged. In more detail: the ring magnet 3G is sufficient for a group of magnetically different magnets to stagger each other - The main feature of the ring shape is that it is sleeved in the rotor body 2〇5. The main feature of the creation is that the annular magnet 3〇 and the opposite wall of the outer rotor cylinder are provided with a conductive magnetic composite body (as shown in Figure 3). H). The body 40 is at least uniformly formed by a rubber material 41 and a magnetic fluid particle (rofluid)-type material. The rubber material is mainly composed of a rubber sheet material, and may also be composed of a hard rubber material. Preferably, the inner and outer surfaces of the conductive magnetic composite body 40 are provided with a ridged road 411 or a path for increasing the friction between the outer rotor cylinder 2 and the annular magnet to prevent the outer rotor cylinder 2 and the annular magnet. If the torque is too large due to excessive torque, it will be idling (as shown in Figure 4). 3 The magnetic fluid particles 42 are mainly composed of magnetite, hematite or iron. The magnetic particles of the magnets and the magnetic nanoparticles of the thieves have a paramagnetic property and a high magnetic susceptibility characteristic. When the conductive magnetic composite 40 is actually produced, the magnetic fluid particles 42 are combined with the fluid-like rubber alloy 41.

P may further include: a plurality of pieces of elastic steel sheet 43 (as shown in FIG. 5); ', each of the elastic steel sheets 43 is pressed against the inner wall surface of the outer rotor cylinder 2 and the outer side wall surface of the annular magnet 30 ( As shown in Fig. 6), it is responsible for absorbing the vibration force between the two corresponding walls. In this embodiment, each of the elastic steel sheets 43 can be further divided into a steel sheet upper portion 431 and a steel sheet lower portion 432. The upper steel sheet portion 431 and the lower steel sheet portion 432 are respectively pressed against the outer rotor cylinder 2 and the annular magnet 3G. (As shown in Fig. 6), and with the use of its own elastic force, the cylindrical body 2G and the vibration force generated when the magnet 3 rotates are absorbed.
