Description

Technical Field

[0001] This utility model relates to the field of permanent magnet synchronous motor technology, specifically a heat dissipation base for a permanent magnet synchronous motor. Background Technology

[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a magnetic field. The speed of its rotor is consistent with the frequency of the current in the stator winding. A permanent magnet synchronous motor consists of components such as a stator, rotor, end cover, motor housing, and base. The base of a permanent magnet synchronous motor is mostly used to support the motor.

[0003] Permanent magnet synchronous motors generate a lot of heat during operation, resulting in high internal temperatures. Existing permanent magnet synchronous motors use heat sinks installed on the outer casing to physically dissipate heat. While this heat dissipation structure is simple, it has low heat dissipation efficiency. Furthermore, the base used to support the motor mostly serves a supporting function and has a single purpose. Therefore, to address the above issues, we propose a heat dissipation base for permanent magnet synchronous motors. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution:

A base body 3 is fixedly connected to the lower outer side of the permanent magnet synchronous motor body 1. A heat-conducting plate 4 is fixedly connected to the upper inner side of the base body 3. A second heat sink 5 is fixedly connected to the lower end of the heat-conducting plate 4. A flow equalization plate 6 is fixedly connected to the inside of the base body 3. A support frame 7 is fixedly connected to the inside of the base body 3. A cooling fan 8 is provided at the lower end of the support frame 7.

Filter plates 11 are provided at both ends of the base body 3. A first magnet 12 is fixedly connected to the inner side of the filter plate 11 near the air inlet slot 9. A second magnet 13 is fixedly connected to the inner side of both ends of the base body 3. Heat dissipation slots 14 are opened at both ends of the base body 3. A handle 15 is fixedly connected to the side of the filter plate 11 away from the heat dissipation slot 14.

[0023] The base body 3 has an inverted "U" shaped cross-section. The upper surface of the heat-conducting plate 4 is attached to the lower surface of the permanent magnet synchronous motor body 1. There are several second heat sinks 5, which are located above the flow equalization plate 6. The flow equalization plate 6 is located above the support frame 7. There are two cooling fans 8. The air inlet slot 9 is located below the heat dissipation slot 14. There are two filter plates 11, which are located outside the air inlet slot 9 and outside the heat dissipation slot 14. The first magnet 12 and the second magnet 13 are magnetically attracted to each other. The lower second magnet 13 is located in the air inlet slot. Below 9, the upper second magnet 13 is located above the heat dissipation slot 14. There are four second magnets 13. The outer side of the permanent magnet synchronous motor body 1 is provided with a first heat sink 2. The lower outer side of the permanent magnet synchronous motor body 1 is fixedly connected to a base body 3. The upper inner side of the base body 3 is fixedly connected to a heat conduction plate 4, which facilitates the installation of the heat conduction plate 4, the second heat sink 5, the flow equalization plate 6, the support frame 7, the cooling fan 8, the air inlet slot 9, and the filter plate 11. When the permanent magnet synchronous motor body 1 is powered on, the support frame 7 supports the cooling fan 8, which is controlled by an external controller. When the cooling fan 8 is activated, it rotates, allowing air to quickly enter the base body 3 through the air inlet slot 9, accelerating air circulation. The air distribution plate 6 ensures even air distribution. The heat conduction plate 4 conducts heat from the bottom of the permanent magnet synchronous motor body 1, and the second heat sink 5 increases the heat dissipation area, allowing heat to dissipate quickly and flow out from the heat dissipation slot 14. This device enables the base body 3 to have a heat dissipation function and improves the overall heat dissipation efficiency. The second heat sink 5 is fixedly connected to the lower end of the heat conduction plate 4, and the air distribution plate 6 is fixedly connected inside the base body 3. The main body 3 is internally fixedly connected to a support frame 7. A cooling fan 8 is provided at the lower end of the support frame 7. Air inlet slots 9 are provided at both ends of the main body 3. An anti-slip pad 10 is fixedly connected to the bottom of the main body 3. A filter plate 11 is provided at both ends of the main body 3. A first magnet 12 is fixedly connected to the inner side of the filter plate 11 near the air inlet slot 9. A second magnet 13 is fixedly connected to the inner side of both ends of the main body 3. A heat dissipation slot 14 is provided at both ends of the main body 3. A handle 15 is fixedly connected to the side of the filter plate 11 away from the heat dissipation slot 14.

[0024] Workflow: When the device is in use, it is powered by an external power source. The permanent magnet synchronous motor body 1 generates a large amount of heat during prolonged use. This heat is first dissipated outwards through the first heat sink 2, then the heat conduction plate 4 conducts heat to the bottom of the permanent magnet synchronous motor body 1. The second heat sink 5 increases the heat dissipation area at the bottom. Simultaneously, the cooling fan 8 is activated via an external controller. The cooling fan 8 rotates, allowing air to quickly enter the base body 3 through the air inlet slot 9, accelerating airflow. The air distribution plate 6 ensures even upward distribution of air, allowing the heat on the second heat sink 5 to dissipate quickly and promptly from the heat dissipation slot 1. 4. The exhaust system improves the overall heat dissipation efficiency and enhances the performance of the base body 3, making it more practical. The second magnet 13 and the first magnet 12 are magnetically attracted to each other, fixing the filter plate 11 to the left and right sides of the base body 3. This allows the filter plate 11 to effectively filter dust in the air, reducing dust blockage of the flow equalization plate 6 and extending its service life. When the filter plate 11 needs cleaning after long-term use, simply pull outwards the handle 15 to remove the filter plate 11 for cleaning. The operation is simple. The anti-slip pad 10 makes the base body 3 more stable.
