Description

Technical Field

[0001] The utility model belongs to the field of motors, relates to a stator and rotor, and particularly relates to a novel stator and rotor. Background Art

[0002] As the name implies, the stator is the stationary part in a motor or pump body. The rotatable cylindrical component arranged inside this object is called the rotor. After connecting to the power supply, the two generate electromagnetic induction through the coil and the magnet, and then drive the connected shaft body and external objects to rotate. Most of the conventional stator and rotor structures rely on a fan for external heat dissipation, and its heat dissipation effect is not ideal. In the case of a water pump motor with high-intensity work, the internal heat cannot be volatilized and dissipated in time, resulting in heat accumulation, which seriously affects the service life and efficiency of the stator and rotor. Summary of the Invention

[0003] The purpose of the utility model is to provide a novel stator and rotor to solve the above problems in view of the above problems existing in the prior art.

[0004] The purpose of the utility model can be achieved by the following technical solutions: A novel stator and rotor, including a stationary stator part, a rotatable rotor part, and a shaft body for driving connection. It is characterized in that there is a gap between the stator part and the rotor part;

[0005] The rotor part includes a rotor core for the shaft body to penetrate, a plurality of heat dissipation fins for improving the heat dissipation efficiency, and a heat dissipation skeleton located between the rotor core and the heat dissipation fins;

[0006] A plurality of heat dissipation through holes for improving the internal heat dissipation efficiency are provided through the rotor core;

[0007] The heat dissipation skeleton is composed of a plurality of fixing rings and a plurality of connecting ribs;

[0008] A plurality of the connecting ribs are arranged at intervals in a circumferential direction along the outside of the rotor core;

[0009] There is a heat dissipation gap for rapid air circulation and heat dissipation between two adjacent connecting ribs;

[0010] A plurality of the heat dissipation fins are fixedly connected to the outside of a plurality of fixing rings and are arranged in a spaced and stacked structure. Each heat dissipation fin is staggered in sequence in the circumferential direction and cooperates to form a spiral groove.

[0011] In the above-mentioned novel stator and rotor, a plurality of the heat dissipation fins, fixing rings, connecting ribs and rotor core are of an integrally formed structure, and the heat dissipation fins are stabilized by connecting columns, and the connecting columns are sequentially penetrated and connected to the heat dissipation fins.

[0012] In the above-mentioned novel stator-rotor, the rotor part generates electromagnetic induction through a coil and a magnet, so that the rotor iron core drives the heat dissipation fins and the heat dissipation skeleton to rotate, realizing the self-cooling effect.

[0013] In the above-mentioned novel stator-rotor, the heat dissipation fins can be arranged in a spline structure.

[0014] Compared with the prior art, the novel stator-rotor has a simple structural design. By using the cooperation of the rotor iron core, the heat dissipation fins and the heat dissipation skeleton, it can effectively conduct rapid air cooling on the internal heat, thus realizing high heat dissipation efficiency, greatly reducing the problem of internal heat accumulation, and improving the service life and efficiency of the stator-rotor.

[0019] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0020] As Figure 1 、 Figure 2 、 Figure 3 shown, the novel stator-rotor includes a stator part 1 that can be fixed in place, a rotor part 2 that can rotate, and a shaft body 3 that is drivingly connected. There is a gap between the stator part 1 and the rotor part 2. The rotor part 2 includes a rotor iron core 4 through which the shaft body 3 passes, several heat dissipation fins 5 for improving the heat dissipation efficiency, and a heat dissipation skeleton located between the rotor iron core 4 and the heat dissipation fins 5. A plurality of heat dissipation through holes 6 for improving the internal heat dissipation efficiency are provided through the rotor iron core 4. The heat dissipation skeleton is composed of several fixing rings 7 and several connecting ribs 8. The several connecting ribs 8 are arranged at intervals in a circumferential direction along the outside of the rotor iron core 4. There is a heat dissipation gap 9 for rapid air circulation and heat dissipation between two adjacent connecting ribs 8. The several heat dissipation fins 5 are fixedly connected to the outside of the several fixing rings 7 and are arranged in an interval superposition structure. Each heat dissipation fin 5 is offset in sequence along the circumferential direction and cooperates to form a spiral groove 10.

[0021] The above structure is simply designed. By cooperating with the rotor core 4, heat dissipation fins 5 and the heat dissipation skeleton structure, it can effectively perform rapid air cooling on the internal heat, thereby achieving high heat dissipation efficiency, greatly reducing the problem of internal heat accumulation, and improving the service life and efficiency of the stator and rotor.

[0022] To elaborate further, in order to improve the air cooling heat dissipation efficiency of the rotor part 2 during the rotational movement, several heat dissipation fins 5, fixing rings 7, connecting ribs 8 and the rotor core 4 are integrally formed structures. The heat dissipation fins 5 are stabilized by connecting columns, and the connecting columns are sequentially penetrated and connected to the heat dissipation fins 5.

[0023] To elaborate further, by utilizing the characteristics that the stator part 1 is stationary and the rotor part 2 rotates, air cooling heat dissipation during the rotation process of the rotor part 2 is achieved. The rotor part 2 generates electromagnetic induction through the coil and the magnet, so that the rotor core 4 drives the heat dissipation fins 5 and the heat dissipation skeleton to rotate, realizing the self-heat dissipation effect.

[0024] To elaborate further, in order to improve the heat dissipation efficiency, the heat dissipation fins 5 can be arranged in a spline structure.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0026] Although terms such as stator part 1, rotor part 2, shaft body 3, rotor core 4, heat dissipation fins 5, heat dissipation through holes 6, fixing rings 7, connecting ribs 8, heat dissipation gaps 9, spiral grooves 10, etc. are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
