Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a low-power, long-endurance energy-saving motor and its manufacturing method. Background Technology

[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuits, an electric motor is represented by the letter M. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, electric motors are indispensable in industrial production.

[0003] The power consumption of existing motors is greatly affected by temperature. To ensure effective heat dissipation, the dust cover of the motor is usually designed with a quick-release mechanism for easy disassembly and cleaning. However, the cleaning interval is manually specified and relatively random, which can lead to situations where severe blockage of the dust cover goes undetected, causing the motor to continue operating. This results in higher motor temperatures and increased energy consumption, as well as reduced functionality. Furthermore, existing motors cannot detect load during use, leading to overload and continuous high-power operation, increasing motor wear, shortening its lifespan, and resulting in poor performance. Therefore, there is an urgent need for a low-power, long-endurance, energy-saving motor to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a low-power, long-endurance energy-saving motor and its manufacturing method in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A low-power, long-lasting energy-saving motor includes a motor body. An end cover is fixed to one end of the motor body, and a dustproof mesh is installed inside the end cover. Two sets of brackets are symmetrically installed inside and outside the middle of the dustproof mesh. An external wind pressure sensor is fixed to one end of the external bracket, and an internal wind pressure sensor is fixed to one end of the internal bracket. Heat dissipation fins are distributed circumferentially on the outer wall of the motor body. A controller is fixed to one side of the upper end of the motor body, and a warning light is installed on one side of the top of the controller. Two sets of operating chambers are symmetrically opened on one side wall of the dustproof mesh. A telescopic rod is installed inside the operating chamber, and a spring is built into the telescopic rod. A lever is fixed to the movable part of the telescopic rod. A limit rod is fixed on one side wall of the lever, and a limit hole is opened on the side wall of the end cover at a position corresponding to the limit rod. A positioning cavity is also opened at the upper end of the end cover. A positioning block matching the specifications of the positioning cavity is fixed at the top of the dustproof net. A cooling fan blade is fixed at one end of the rotor inside the motor body, and an output shaft is fixed at the other end of the rotor inside the motor body. A bearing seat is installed between the output shaft and the outer shell of the motor body. A keyway is opened at one end of the output shaft, and a torque sensor is installed on the output shaft. Mounting seats are symmetrically fixed on the outer side of the bottom end of the motor body, and vibration sensors are installed on the mounting seats. A buzzer is installed on one side of the warning light.

[0007] Furthermore, the end cap is fixed to the outer casing of the motor body by screws, and the dustproof mesh is inserted into the end cap.

[0008] By adopting the above technical solution, the dustproof net can prevent dust from entering the motor body.

[0009] Furthermore, the bracket is fixed to the middle of the dustproof net with screws, and both the external wind pressure sensor and the internal wind pressure sensor are fixed to one end of the bracket with screws. The internal wind pressure sensor and the external wind pressure sensor are not in contact with the dustproof net.

[0010] By adopting the above technical solution, during the dust prevention process, the combination of the inner wind pressure sensor and the outer wind pressure sensor can detect the wind pressure on both sides of the dust prevention net.

[0011] Furthermore, the controller is electrically connected to the motor body, the internal wind pressure sensor and the external wind pressure sensor are both electrically connected to the controller, and the warning light is electrically connected to the controller.

[0012] By adopting the above technical solution, the external wind pressure sensor and the internal wind pressure sensor transmit the detected data to the controller for processing and analysis. When the difference between the detected values ​​of the two sensors is greater than the set value, it indicates that the dustproof net is seriously clogged. At this time, the warning light will activate to remind the staff to clean the dustproof net in time, so as to avoid poor heat dissipation and excessive internal temperature of the motor body due to untimely cleaning, and keep the motor body in low power consumption operation.

[0013] Furthermore, the heat dissipation fins are welded to the side wall of the outer casing of the motor body, and the heat dissipation fan blades are fixed to one end of the rotor built into the motor body by screws.

[0014] By adopting the above technical solution, the heat dissipation fan blades and heat dissipation fins can dissipate heat from the motor body, thereby cooling its interior.

[0015] Furthermore, the operating cavity is formed on the frame of the dustproof net, the fixed part of the telescopic rod is fixed in the operating cavity by screws, the spring is welded between the movable part and the fixed part of the telescopic rod, the lever is connected to the movable part of the telescopic rod by screws, the lever is slidably connected to the operating cavity, the limiting rod is fixed on one side wall of the lever by screws, the limiting hole is formed on the end cover, and the limiting rod is inserted into the limiting hole.

[0016] By adopting the above technical solution: when disassembling and assembling the dustproof net, only an external force needs to be applied to the lever to compress the telescopic rod and the spring, thereby separating the limiting rod from the limiting hole, allowing the dustproof net to be quickly disassembled. After cleaning, during the installation process, the positioning cavity and the positioning block combine to position the dustproof net. Then, the above operation is repeated, placing the dustproof net inside the end cap, releasing the external force, and relying on the rebound force of the telescopic rod and the spring, the limiting rod can be automatically pushed into the limiting hole, thus realizing the installation of the dustproof net.

[0017] Furthermore, the positioning cavity is formed on the end cap, the positioning block is formed on the frame of the dustproof net, and the positioning block is inserted into the positioning cavity.

[0018] By adopting the above technical solution, the positioning cavity and the positioning block can be combined to position the dustproof net.

[0019] Furthermore, the bearing housing is fixed to one side wall of the motor body housing by screws, the output shaft is rotatably connected to the bearing housing, the keyway is formed on the output shaft, the torque sensor is fixed to the output shaft by a coupling, the vibration sensor is fixed to the mounting base by screws, the torque sensor and the vibration sensor are both electrically connected to the controller, and the buzzer is electrically connected to the controller.

[0020] By adopting the above technical solution: the keyway facilitates connection to external loads; the motor body drives the load through the output shaft; simultaneously, the torque sensor detects the torque of the output shaft; the vibration sensor detects the vibration level of the motor body during operation; and the detected data is transmitted to the controller for processing and analysis. When the detected data exceeds a set value, it indicates that the load is too large and the motor body is overloaded. At this time, the buzzer is activated to remind the operator, allowing them to adjust the load in time, preventing the motor body from continuously operating at high power and increasing its wear and tear, thus improving its endurance and service life.

[0021] Furthermore, the mounting base is welded to the outer casing of the motor body, and the mounting base has mounting holes.

[0022] By adopting the above technical solution, the mounting holes on the mounting base facilitate the installation and fixation of the motor body.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. To address the issue that the power consumption of existing motors is significantly affected by temperature, and to ensure effective heat dissipation, the dust cover of the motor is usually designed with a quick-release mechanism for easy disassembly and cleaning. However, the cleaning interval is manually specified and relatively random, leading to situations where severe dust cover blockage goes undetected, causing the motor to continue operating. This results in both higher motor temperatures and increased energy consumption, as well as reduced functionality. This invention addresses this by incorporating a real-time detection and alert mechanism consisting of an internal and external air pressure sensor and a warning light. During motor operation, the external and internal air pressure sensors transmit data to the controller for processing and analysis. When the difference between the two readings exceeds a set value, it indicates severe dust cover blockage. At this point, the warning light activates to alert the operator, prompting them to clean the dust cover promptly. This prevents poor heat dissipation and excessively high internal temperatures of the motor due to delayed cleaning, ensuring the motor operates at low power consumption and maintains high performance.

[0025] 2. To address the problem that existing motors cannot detect load during use, leading to overload and continuous high-power operation, increased motor wear, and reduced lifespan, resulting in poor performance, this invention introduces a real-time load detection and alert mechanism consisting of a vibration sensor, a torque sensor, and a buzzer. During motor operation, the torque sensor detects the torque on the output shaft, and the vibration sensor detects the vibration level of the motor body. The detected data is transmitted to the controller for processing and analysis. When the detected data exceeds a set value, it indicates a large load and motor overload. At this point, the buzzer is activated to alert the operator, allowing them to adjust the load promptly and prevent continuous high-power operation, thus improving the motor's endurance and lifespan.

[0034] The present invention will be further described below with reference to the accompanying drawings:

[0035] like Figures 1-6 As shown, a low-power, long-lasting energy-saving motor includes a motor body 1. An end cover 6 is fixed to one end of the motor body 1, and a dustproof net 15 is installed inside the end cover 6 to prevent dust accumulation inside the motor body 1. Two sets of brackets 16 are symmetrically installed inside and outside the middle of the dustproof net 15. An external wind pressure sensor 17 is fixed to one end of the external bracket 16, and an internal wind pressure sensor 25 is fixed to one end of the internal bracket 16, which can detect the wind pressure on both sides of the dustproof net 15 to detect the degree of blockage. Heat dissipation fins 2 are distributed circumferentially on the outer wall of the motor body 1 to dissipate heat. A controller 3 is fixed to one side of the upper end of the motor body 1, and a warning light 4 is installed on one side of the top of the controller 3. Two sets of operating chambers 22 are symmetrically opened on one side wall of the dustproof net 15. A telescopic rod 24 is installed inside the operating chamber 22, and a spring 26 is built into the telescopic rod 24. A lever is fixed to the movable part of the telescopic rod 24. Block 23 has a limit rod 21 fixed on one side wall. The end cover 6 has a limit hole 20 on the side wall corresponding to the limit rod 21 to facilitate the disassembly and assembly of the dustproof net 15. The end cover 6 also has a positioning cavity 19. The top of the dustproof net 15 is fixed with a positioning block 14 that matches the specifications of the positioning cavity 19, which can be used to install and position the dustproof net 15. One end of the rotor inside the motor body 1 is fixed with a heat dissipation fan blade 18 to further dissipate heat inside the motor body 1. The other end of the rotor inside the motor body 1 is fixed with an output shaft 10. A bearing seat 11 is installed between the output shaft 10 and the outer shell of the motor body 1. One end of the output shaft 10 has a keyway 13. A torque sensor 12 is installed on the output shaft 10. The bottom outer side of the motor body 1 is symmetrically fixed with a mounting seat 7. A vibration sensor 9 is installed on the mounting seat 7. A buzzer 5 is installed on one side of the warning light 4 to detect the output load of the motor body 1.

[0036] In this embodiment, the end cover 6 is fixed to the outer shell of the motor body 1 by screws, and the dustproof net 15 is inserted into the end cover 6. The dustproof net 15 can prevent dust inside the motor body 1.

[0037] In this embodiment, the bracket 16 is fixed to the middle of the dustproof net 15 with screws. The external wind pressure sensor 17 and the internal wind pressure sensor 25 are both fixed to one end of the bracket 16 with screws. The internal wind pressure sensor 25 and the external wind pressure sensor 17 do not contact the dustproof net 15. During the dustproof process, the internal wind pressure sensor 25 and the external wind pressure sensor 17 can be combined to detect the wind pressure on both sides of the dustproof net 15.

[0038] In this embodiment, the controller 3 is electrically connected to the motor body 1, the internal wind pressure sensor 25 and the external wind pressure sensor 17 are both electrically connected to the controller 3, and the warning light 4 is electrically connected to the controller 3. The external wind pressure sensor 17 and the internal wind pressure sensor 25 transmit the detection data to the controller 3 for processing and analysis. When the difference between the two detection values ​​is greater than the set value, it indicates that the dust filter 15 is seriously blocked. At this time, the warning light 4 will activate to remind the staff to clean the dust filter 15 in time, so as to avoid poor heat dissipation and excessive internal temperature of the motor body 1 due to untimely cleaning, and keep the motor body 1 in low power consumption operation.

[0039] In this embodiment, the heat dissipation fins 2 are welded to the outer wall of the motor body 1, and the heat dissipation fan blades 18 are fixed to one end of the rotor inside the motor body 1 by screws. The heat dissipation fan blades 18 and the heat dissipation fins 2 can dissipate the heat inside the motor body 1, thereby cooling its interior.

[0040] In this embodiment, the operating cavity 22 is formed on the frame of the dustproof net 15. The fixed part of the telescopic rod 24 is fixed in the operating cavity 22 by screws. The spring 26 is welded between the movable part and the fixed part of the telescopic rod 24. The lever 23 is connected to the movable part of the telescopic rod 24 by screws. The lever 23 is slidably connected to the operating cavity 22. The limiting rod 21 is fixed to one side wall of the lever 23 by screws. The limiting hole 20 is formed on the end cover 6. The limiting rod 21 is inserted into the limiting hole 20. When disassembling and assembling the dustproof net 15, only the lever needs to be adjusted. Block 23 applies external force to compress the telescopic rod 24 and spring 26, thereby separating the limiting rod 21 from the limiting hole 20, allowing for quick disassembly of the dustproof net 15. After cleaning, during installation, the positioning cavity 19 and positioning block 14 combine to position the dustproof net 15. Then, repeat the above operation, place the dustproof net 15 inside the end cover 6, release the external force, and rely on the rebound force of the telescopic rod 24 and spring 26 to automatically push the limiting rod 21 into the limiting hole 20, thus realizing the installation of the dustproof net 15.

[0041] In this embodiment, the positioning cavity 19 is formed on the end cap 6, and the positioning block 14 is formed on the frame of the dustproof net 15. The positioning block 14 is inserted into the positioning cavity 19, and the positioning cavity 19 and the positioning block 14 can be combined to position the dustproof net 15.

[0042] In this embodiment, the bearing housing 11 is fixed to one side wall of the motor body 1 housing by screws. The output shaft 10 is rotatably connected to the bearing housing 11. The keyway 13 is formed on the output shaft 10. The torque sensor 12 is fixed to the output shaft 10 by a coupling. The vibration sensor 9 is fixed to the mounting base 7 by screws. The torque sensor 12 and the vibration sensor 9 are electrically connected to the controller 3. The buzzer 5 is electrically connected to the controller 3. The keyway 13 facilitates connection to an external load. The motor body 1 drives the load to work through the output shaft 10. At the same time, the torque sensor 12 detects the torque of the output shaft 10, and the vibration sensor 9 detects the vibration level of the motor body 1 during operation. The detected data is transmitted to the controller 3 for processing and analysis. When the detected data is greater than the set value, it indicates that the load is too large and the output of the motor body 1 is overloaded. At this time, the buzzer 5 is controlled to work to remind the staff so that the staff can adjust the load in time, avoid the motor body 1 from running at high power continuously, which would increase its wear and tear, and improve its endurance and service life.

[0043] In this embodiment, the mounting base 7 is welded to the outer shell of the motor body 1, and the mounting base 7 is provided with mounting holes 8, which facilitates the installation and fixing of the motor body 1.

[0044] A method for manufacturing a low-power, long-endurance energy-saving motor: First, the motor body 1 is installed and fixed through the mounting holes 8 on the mounting base 7. Then, the output shaft 10 is connected to the load through the keyway 13, and then external three-phase power is connected. During use, the motor body 1 drives the load through the output shaft 10. At the same time, the torque sensor 12 detects the torque of the output shaft 10, and the vibration sensor 9 detects the vibration level of the motor body 1 during operation. The detected data is transmitted to the controller 3 for processing and analysis. When the detected data is greater than the set value, it indicates that the load is too large and the output of the motor body 1 is overloaded. At this time, the buzzer 5 is controlled to work to remind the operator to adjust the load in time, so as to avoid the motor body 1 from running at high power continuously, which would increase its wear and tear, improve its endurance and service life. The cooling fan blades 18 and the cooling fins 2 can dissipate heat from the motor body 1, thereby cooling its internal structure. The dustproof net 15 protects the inside of the motor body 1 from dust. However, as the usage time increases, dust will accumulate on the surface of the dustproof net 15, which will lead to the existence of air pressure on both sides. The difference lies in the internal wind pressure sensor 25 and the external wind pressure sensor 17. These sensors work together to detect the wind pressure on both sides of the dustproof net 15 and transmit the data to the controller 3 for processing and analysis. When the difference between the detected values ​​exceeds a set value, it indicates that the dustproof net 15 is severely clogged. At this point, the warning light 4 activates to alert the staff, prompting them to clean the dustproof net 15 promptly. This prevents poor heat dissipation and excessively high internal temperature of the motor body 1 due to delayed cleaning, which would otherwise cause the motor body 1 to operate at low power consumption. During the process, simply apply external force to the lever 23 to compress the telescopic rod 24 and the spring 26, thereby separating the limiting rod 21 from the limiting hole 20 and quickly disassembling the dustproof net 15. After cleaning, during the installation process, the positioning cavity 19 and the positioning block 14 combine to position the dustproof net 15. Then, repeat the above operation, place the dustproof net 15 inside the end cover 6, release the external force, and rely on the rebound force of the telescopic rod 24 and the spring 26 to automatically push the limiting rod 21 into the limiting hole 20, thus realizing the installation of the dustproof net 15.
