Description

Technical Field

[0001] This utility model relates to the field of three-phase asynchronous motor technology, and in particular to a three-phase asynchronous motor with a high-efficiency heat dissipation and dust prevention structure. Background Technology

[0002] Three-phase asynchronous motors are a type of electric motor that is powered by a 380V three-phase AC power supply. Because the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, hence the name three-phase asynchronous motor.

[0003] The problems compared with existing technologies are as follows: The heat dissipation structure of existing three-phase asynchronous motors is relatively simple, generally using axial heat dissipation fins and a cooling fan at the tail to dissipate heat during operation. The heat dissipation efficiency is low. In particular, the tail heat dissipation structure is relatively open, which poses a risk of dust entering during use. It is not suitable for harsh working conditions such as mining and textile industries, affecting the stability of the three-phase asynchronous motor operation and resulting in poor practicality. To address these issues, we propose a three-phase asynchronous motor with a high-efficiency heat dissipation and dust prevention structure. Utility Model Content

[0032] Please see Figure 1-9This utility model provides a technical solution: it includes a three-phase asynchronous motor body 100, a controller 110 is fixed to the top of the three-phase asynchronous motor body 100 by bolts, an installation mechanism is provided at the bottom of the three-phase asynchronous motor body 100, an output mechanism is provided at one end of the three-phase asynchronous motor body 100, a heat dissipation mechanism is provided on the outside of the three-phase asynchronous motor body 100, the heat dissipation mechanism includes axial heat dissipation fins 410, spiral heat dissipation fins 420 and a mounting shaft 430, a fastening bolt 431 is provided at one end of the mounting shaft 430, a cooling fan 440 is fixed to the outside of the mounting shaft 430, and a protective mechanism is provided on the side wall of the three-phase asynchronous motor body 100;

[0033] The protective mechanism includes a mounting block 510, a protective cover 520, and mounting studs 530. The protective cover 520 has multiple honeycomb heat dissipation holes 540 on one side. A first sealing mechanism is provided on the inner wall of the protective cover 520, and a second sealing mechanism is provided on the side wall of the protective cover 520. By providing the heat dissipation mechanism and the protective mechanism, the axial heat dissipation fins 410 and the spiral heat dissipation fins 420 work together to dissipate heat from the exterior of the three-phase asynchronous motor. The added spiral heat dissipation fins 420 optimize the external heat dissipation airflow of the three-phase asynchronous motor, forming a dual-channel heat dissipation structure in both the axial and radial directions, thus improving the heat dissipation efficiency of the three-phase asynchronous motor. The first and second sealing mechanisms seal and protect the protective cover 520 and the air inlet and outlet, and filter the incoming and outgoing air, reducing the risk of dust entering the protective cover 520. The three-phase asynchronous motor is suitable for use in harsh working conditions such as mining and textile industries, improving the stability of the three-phase asynchronous motor during long-term operation.

[0034] Specifically, the installation mechanism includes a mounting base 210, which is fixed to the bottom of the three-phase asynchronous motor body 100 by bolts. A mounting base plate 220 is fixed to the bottom of the mounting base 210, and mounting holes 230 are provided on the outer side of the mounting base plate 220. With the installation mechanism, when the three-phase asynchronous motor needs to be installed, the mounting base plate 220 is placed on the usage position, the mounting holes 230 are aligned with the mounting hole positions, and the three-phase asynchronous motor is installed and fixed by bolts.

[0035] Specifically, the output mechanism includes a mounting plate 310, which is fixed to one end of the three-phase asynchronous motor body 100. A drive shaft 320 is rotatably connected to the inner wall of the mounting plate 310. A positioning key 321 is provided on the inner wall of the drive shaft 320. A sealing ring 330 is fixed to one side of the mounting plate 310, and a docking ring 340 is fixed to the outer side of the mounting plate 310. The docking ring 340 is fixedly connected to the three-phase asynchronous motor body 100. By providing an output mechanism, the output end of the three-phase asynchronous motor is connected to the outside through the cooperation of the positioning key 321 and the drive shaft 320. The sealing ring 330 seals the rotating part of the drive shaft 320, which can reduce lubricating oil leakage and external moisture entering the interior of the three-phase asynchronous motor, thus ensuring the stability of the three-phase asynchronous motor operation.

[0036] Specifically, the mounting block 510 has a positioning groove 511 on its outer side, and the protective cover 520 has a positioning slider 521 fixed inside. The positioning slider 521 is slidably connected to the positioning groove 511. By providing the positioning groove 511 and the positioning slider 521, when installing the protective cover 520, the positioning slider 521 is aligned with the positioning groove 511, which can position and install the protective cover 520, ensuring the accuracy of the installation of the protective cover 520.

[0037] Specifically, the first sealing mechanism includes a dust filter A610, which is fixed to the inner wall of the protective cover 520. A sealing ring 611 is fixed to the inner wall of the dust filter A610. Multiple mounting clips 620 are fixed to one side of the dust filter A610, and a positioning post 630 is fixed to one side of each mounting clip 620. A positioning block 640 is slidably connected to the outer side of each positioning post 630, and the positioning block 640 is fixedly connected to the protective cover 520. Through the provision of this first sealing mechanism... When installing the protective cover 520, align the positioning post 630 with the positioning insert 640 and insert it to position and install the dust filter A610. The sealing ring 611 is tightly attached to the outside of the three-phase asynchronous motor body 100 to seal the gap between the protective cover 520 and the three-phase asynchronous motor body 100. During heat dissipation operation, external air enters the interior of the protective cover 520 through the dust filter A610. The dust filter A610 can filter the incoming air to prevent dust from entering the heat dissipation space inside the protective cover 520.

[0038] Specifically, the second sealing mechanism includes a Velcro A710, which is fixed to the inner wall of the protective cover 520. A Velcro B720 is provided on one side of the Velcro A710, and a dust filter B730 is fixed to the inner wall of the Velcro B720. With this second sealing mechanism, during heat dissipation, the cooling fan 440 rotates and blows air towards the honeycomb heat dissipation holes 540. The dust filter B730 filters the blown air, preventing external air from entering the protective cover 520 through the honeycomb heat dissipation holes 540. Combined with the first sealing mechanism, this provides comprehensive filtration and sealing of the heat dissipation space inside the protective cover 520, reducing the risk of dust entering the protective cover 520. The three-phase asynchronous motor is suitable for harsh working conditions such as mining and textile industries, improving the stability of long-term operation. The Velcro A710 and Velcro B720 allow for easy disassembly and installation of the dust filter B730, facilitating its replacement.

[0039] Working Principle: During use, the controller 110 controls the operation of the three-phase asynchronous motor. When installing the motor, the mounting base 220 is placed on the usage location, the mounting holes 230 are aligned with the mounting positions, and the motor is installed and fixed with bolts. The output end of the motor is connected to the outside via the positioning key 321 and the drive shaft 320. The rotating parts of the drive shaft 320 are sealed with a sealing ring 330. When installing the protective cover 520, the positioning slider 521 is aligned with the positioning groove 511 to position and install the cover. Finally, the cover 520 is fixed to the mounting block 510 with the mounting studs 530. When installing the protective cover 520, the positioning pin 630 is aligned with the positioning insert 640 and inserted to position and install the dust filter A610, thus sealing the dust filter. The rubber ring 611 is tightly attached to the outside of the three-phase asynchronous motor body 100, which can seal the gap between the protective cover 520 and the three-phase asynchronous motor body 100. During heat dissipation operation, external air enters the interior of the protective cover 520 through the dust filter A610. The dust filter A610 can filter the incoming air to prevent dust from entering the heat dissipation space inside the protective cover 520. During heat dissipation operation, the cooling fan 440 rotates and blows air towards the honeycomb heat dissipation holes 540. The dust filter B730 filters the blown air to prevent external air from entering the interior of the protective cover 520 through the honeycomb heat dissipation holes 540. Together with the first sealing mechanism, it can filter and seal the heat dissipation space inside the protective cover 520 in all directions, which can reduce the risk of dust entering the protective cover 520. The three-phase asynchronous motor can be used in harsh working conditions such as mining and textile.
