Description

Technical Field

[0001] This invention relates to the field of motor technology, and more specifically, to an integrated intelligent variable frequency speed control permanent magnet motor. Background Technology

[0002] With the rapid development of industrial automation and intelligent manufacturing, permanent magnet motors are widely used in CNC machine tools, robots, new energy vehicles and other fields due to their high efficiency, high power density and precise speed regulation performance. Among permanent magnet motors, the internal permanent magnet (IPM) rotor structure is one of the mainstream technical routes. Its core feature is that rare earth permanent magnets (such as neodymium iron boron magnets) are embedded or inserted into the core slots of the rotor core to form an embedded magnet structure. The embedded permanent magnet structure can effectively utilize reluctance torque to improve the power density and overload capacity of the motor. However, the heat dissipation path is blocked after the permanent magnet is wrapped by the core, resulting in low heat conduction efficiency.

[0003] Currently, most traditional permanent magnet motor cooling solutions rely solely on separate air or water cooling methods. This single cooling mode is insufficient to meet the diverse cooling requirements of the motor under different operating conditions, resulting in poor overall cooling performance and difficulty in effectively ensuring the stability and reliability of the motor during long-term, high-load operation. To address this, we propose an integrated intelligent variable frequency speed control permanent magnet motor. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an integrated intelligent variable frequency speed control permanent magnet motor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated intelligent variable frequency speed control permanent magnet motor, comprising a base, a motor device mounted on the top of the base, a rotating shaft at one end of the motor device, a bevel gear I mounted on the outside of the rotating shaft, a control component and a connecting shaft I rotatably connected inside the base, a bevel gear II mounted on the top of the control component, a synchronous pulley I and a synchronous pulley II mounted on the outside of the control component and the connecting shaft I respectively, a synchronous belt shared by the outside of the synchronous pulleys I and II, a gear III mounted on the outside of the connecting shaft I, and fan blades mounted on the top of the connecting shaft I. The internal sliding connection is a rack, and an electromagnet is installed at one end of the rack and on the side near the motor device. A connecting frame is installed at one end of the rack, and several sets of adjusting plates are installed on one side of the connecting frame. Several sets of ventilation holes are opened on the outside of the motor device. Filter cotton is installed on the outside of the motor device at the position of the ventilation holes. A temperature detector is installed on one side of the inside of the motor device. A heat sink is installed on the outside of the motor device. An explosion-proof shell is installed on the outside of the heat sink. Several sets of interconnected ventilation holes are opened inside the heat sink. Several sets of water pipes are installed inside the heat sink. Several sets of ventilation holes are opened at both ends of the explosion-proof shell. The control component includes a second connecting shaft connected inside the base. The top of the second connecting shaft has a slot, and inside the slot are two symmetrical positioning slots. A rotating groove is formed at the top edge of the second connecting shaft, and an electromagnet is installed inside the slot. A connecting rod is connected to the top of the second connecting shaft, and a rotating plate is installed at the bottom edge of the connecting rod. The rotating plate is rotatably connected inside the rotating groove. A groove is formed inside the connecting rod, and a spring is installed inside the groove. A connecting plate is installed at one end of the spring. Positioning plates are installed on both sides of the outer side of the connecting plate. The groove has symmetrical sliding grooves that slide with the positioning plates.

[0006] Preferably, the connecting plate corresponds to the electromagnet, and the connecting plate is made of iron, and the positioning plate is compatible with the positioning groove.

[0007] Preferably, the top of both the control component and the connecting shaft one penetrates the base and extends into the interior of the motor device, the bevel gear two is located at the bottom of the bevel gear one, and the bevel gear two meshes with the teeth of the bevel gear one.

[0008] Preferably, gear three is a single-tooth gear, whose teeth intermittently mesh with the teeth of the rack to drive the rack to perform reciprocating linear motion.

[0009] Preferably, there are several sets of ventilation holes, which correspond to several sets of adjustment plates. The initial opening area of ​​each set of ventilation holes is blocked by three-quarters of the adjustment plate, which is used to dynamically adjust the heat dissipation efficiency.

[0010] The technical effects and advantages of this invention are as follows: In use, this invention utilizes a combination of fan cooling and water cooling to improve heat dissipation. A temperature detector monitors the motor's internal temperature in real time; when the temperature exceeds a set threshold, the control component automatically activates, driving the adjustment plate to move and expand the effective area of ​​the ventilation holes, accelerating airflow. Once the temperature decreases, the adjustment plate returns to its initial position, limiting airflow to reduce energy consumption. When gear three disengages, electromagnet two is energized and attracts the motor's inner wall, driving the rack to quickly reset, ensuring continuous and precise heat dissipation adjustment. Compared to traditional fixed cooling fans, this invention can dynamically adjust heat dissipation power according to actual needs, reducing energy consumption while avoiding demagnetization of the internal permanent magnet and motor performance degradation caused by high temperatures.

[0011] When in use, the invention features a removable filter cotton on the outside of the ventilation hole, which effectively filters dust and oil and absorbs odors, preventing impurities from entering the motor. The filter cotton is particularly crucial for the long-term stable operation of the internal permanent magnet motor and the effective control of the heat of the internal permanent magnet.

[0024] As attached Figures 1-10The intelligent variable frequency speed control permanent magnet motor integrated machine shown includes a base 1, a motor device 2 mounted on the top of the base 1, a rotating shaft 3 at one end of the motor device 2, a bevel gear 4 mounted on the outside of the rotating shaft 3, a control component 5 and a connecting shaft 6 rotatably connected inside the base 1, a bevel gear 7 mounted on the top of the control component 5, and the tops of both the control component 5 and the connecting shaft 6 extending through the base 1 and into the interior of the motor device 2, the bevel gear 7 being located at the bottom of the bevel gear 4 and meshing with the teeth of the bevel gear 4, a synchronous pulley 8 and a synchronous pulley 9 mounted on the outside of the control component 5 and the connecting shaft 6 respectively, a synchronous belt 10 shared by the synchronous pulleys 8 and 9, a gear 11 mounted on the outside of the connecting shaft 6, a fan blade 12 mounted on the top of the connecting shaft 6, a rack 13 slidably connected inside the motor device 2, and an electromagnet 2 mounted on one end of the rack 13 near the side of the motor device 2. 19. Gear 3 11 is a single-tooth gear, whose teeth intermittently mesh with the teeth of rack 13 to drive rack 13 to perform reciprocating linear motion. A connecting frame 14 is installed at one end of rack 13, and several sets of adjusting plates 15 are installed on one side of connecting frame 14. Several sets of ventilation holes 16 are opened on the outside of motor device 2. Several sets of ventilation holes 16 are provided and correspond to several sets of adjusting plates 15. The initial opening area of ​​each set of ventilation holes 16 is blocked by three-quarters of the adjusting plate 15 to dynamically adjust the heat dissipation efficiency. Filter cotton 17 is installed on the outside of motor device 2 and at the position of ventilation hole 16. Temperature detector 18 is installed on one side of inside motor device 2. Heat sink 22 is installed on the outside of motor device 2. Explosion-proof shell 20 is installed on the outside of heat sink 22. Several sets of interconnected ventilation holes 24 are opened inside heat sink 22. Several sets of water pipes 23 are installed inside heat sink 22. Several sets of ventilation holes 21 are opened at both ends of explosion-proof shell 20. The control component 5 includes a second connecting shaft 51 connected inside the base 1. The top of the second connecting shaft 51 has a slot 52, and the inside of the slot 52 has two symmetrical positioning slots 53. The top edge of the second connecting shaft 51 has a rotating groove 54. An electromagnet 55 is installed inside the slot 52. The top of the second connecting shaft 51 is connected to a connecting rod 56. A rotating plate 57 is installed at the bottom edge of the connecting rod 56. The rotating plate 57 is rotatably connected inside the rotating groove 54. The inside of the connecting rod 56 has a groove 58, and a spring 59 is installed inside the groove 58. A connecting plate 510 is installed at one end of the spring 59. Positioning plates 511 are installed on both sides of the outside of the connecting plate 510. The inside of the groove 58 has symmetrical sliding grooves 512 that slide with the positioning plates 511. The connecting plate 510 corresponds to the electromagnet 55, and the connecting plate 510 is made of iron. The positioning plates 511 are adapted to the positioning grooves 53.

[0025] The bottom of the rack 13 is slidably connected to the inside of the motor device 2 via a slide rail to reduce movement resistance; the electromagnet 2 19 set at one end of the rack 13 cooperates with the inner wall of the motor device 2. When the gear 3 11 moves to the end and disengages, the electromagnet 2 19 is energized to attract iron on one side of the motor device 2, driving the rack 13 to quickly return to the initial position. The filter cotton 17 is fixed to the ventilation hole 16 on the outside of the motor device 2 by a buckle, and can be quickly disassembled for cleaning or replacement; the filter cotton 17 effectively filters dust and absorbs odors. The rotating shaft 3 of the motor device 2 drives the bevel gear 4 to rotate. The bevel gear 4 meshes with the bevel gear 7, transmitting power to the connecting shaft 51 of the control component 5. The connecting shaft 51 transmits power synchronously to the connecting shaft 6 through the synchronous pulley 8, the synchronous belt 10, and the synchronous pulley 9. The fan blades 12 at the top of the connecting shaft 6 rotate at high speed, forming a basic cooling airflow to initially cool the motor device 2. The single-tooth gear 11 outside the connecting shaft 16 intermittently meshes with the rack 13, driving the rack 13 to perform reciprocating linear motion. The rack 13 drives several sets of adjusting plates 15 to move synchronously through the connecting frame 14. The adjusting plates 15 slide along the axial direction of the ventilation hole 16. When the adjustment plate 15 moves to the side of the ventilation hole 16, the ventilation hole 16 is fully opened, which accelerates air circulation and improves heat dissipation efficiency. External air enters the motor device 2 after being filtered by the filter cotton 17, preventing dust from entering and damaging the internal components. When the electromagnet 55 is energized, it generates a magnetic attraction that causes the connecting plate 510 to move downwards. Before the positioning plate 511 enters the positioning groove 53, the spring 59 is in its initial state. As the connecting plate 510 moves against the elastic force of the spring 59, the positioning plate 511 automatically enters the positioning groove 53 when it aligns with the positioning groove 53.

[0026] The working principle of this invention is as follows: A heat sink 22 is installed on the outside of the motor device 2. During internal air cooling, air flows through several sets of ventilation holes 24 to the ventilation holes 21 for exhaust. An explosion-proof shell 20 is installed on the outside of the heat sink 22. The several sets of ventilation holes 24 are connected to the several sets of ventilation holes 21 to facilitate air flow. Several sets of water pipes 23 are installed inside the heat sink 22. The several sets of water pipes 23 are connected in series. One of the water pipes 23 is connected to an external water source to facilitate water cooling. Through the dual effect of air cooling and water cooling, the heat dissipation effect is improved. When the motor device 2 is in use, the temperature detector 18 monitors the internal temperature of the motor device 2 in real time. When the internal temperature of the motor device 2 exceeds the set threshold, the control component 5 is automatically activated. When electromagnet 55 is activated and energized, it generates a magnetic attraction to connecting plate 510. Connecting plate 510 overcomes the elastic force of spring 59 and moves into slot 52. At the same time, positioning plate 511 outside connecting plate 510 moves downward in slide groove 512. When positioning plate 511 moves and is located in positioning groove 53, connecting rod 56 can drive connecting shaft 51 to rotate synchronously. When the power is off, the spring 59 restores its elastic force, bringing the connecting plate 510 back to its original position, and the positioning plate 511 also returns to its initial position accordingly, thus realizing the change of the component state; As the rotating shaft 3 drives the external bevel gear 4 to rotate, the bevel gear 4 meshes with the bevel gear 7 on the top of the control component 5, transmitting power to the control component 5. The control component 5 transmits power synchronously to the connecting shaft 6 through the synchronous pulley 8, the synchronous belt 10 and the synchronous pulley 9, driving the connecting shaft 6 to rotate. The fan blades 12 at the top of the connecting shaft 6 rotate accordingly, forming a basic cooling airflow. The gear 11 on the outside of the connecting shaft 6 intermittently meshes with the rack 13, driving the rack 13 to perform reciprocating linear motion. The rack 13 drives several sets of adjusting plates 15 to move synchronously through the connecting frame 14. The adjusting plates 15 correspond one-to-one with the ventilation holes 16 on the outside of the motor device 2. The adjusting plates 15 block three-quarters of the opening area of ​​the ventilation holes 16, limiting the airflow to reduce energy consumption. The movement of the adjusting plates 15 expands the effective area of ​​the ventilation holes 16, accelerating air circulation. The filter cotton 17 filters the air entering the motor device 2 to prevent dust from entering. When rack 13 moves to the end, electromagnet 2 19 automatically turns on and rack 13 automatically resets when gear 3 11 is not engaged with it.
