Description

Technical Field

[0001] This invention relates to the field of motor technology, specifically to an energy-saving motor with optimized airflow. Background Technology

[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. An electric motor mainly consists of a stator, a rotor, and auxiliary components. Different types of motors differ in structural details, but the core principle remains the same. The basic structure of an electric motor revolves around the stator generating a magnetic field, the rotor rotating under force, and stable operation and electrical energy input achieved through auxiliary components such as bearings, end plates, and wires.

[0003] During operation, the stator and rotor of an electric motor generate heat when the windings are energized, thus requiring heat dissipation. Existing motors typically have a cooling fan installed at the tail end of the main shaft, with an air guide shroud on the outside of the fan. The main shaft drives the cooling fan to rotate, generating airflow. Guided by the air guide shroud, the airflow flows to the cooling fins on the surface of the motor housing. The heat inside the motor is dissipated into the air through the cooling fins, achieving heat dissipation. However, since the rotor is located at the center of the motor and does not contact the housing, when the rotor reaches a high temperature, it cannot be cooled specifically. The only way to cool the entire motor is to increase external heat dissipation, resulting in high energy consumption. The motor's airflow design needs further optimization. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides an energy-saving motor with optimized airflow, comprising a body component. The body component includes a housing and a rotating shaft rotatably mounted on the central axis of the housing and extending through it from left to right. The housing has circumferentially evenly distributed air outlets and air inlets at its left and right ends, respectively.

[0005] The heat dissipation component includes a fan fixedly installed on the right end of the rotating shaft, a front air guide shroud and a rear air guide shroud respectively installed on the left and right ends of the machine casing, the fan being located inside the rear air guide shroud, a sealing assembly installed on the machine casing for controlling the opening and closing of the air outlet and air inlet, and a temperature detection assembly for detecting the internal temperature of the machine casing.

[0006] An adjustment component, installed on the rear air guide cover, is used to control the opening and closing of the air ducts at the edge of the rear air guide cover. When the air outlet and air inlet are open, the air ducts at the edge of the rear air guide cover are closed.

[0007] The guiding component includes an inner air guide pipe and an outer air guide pipe fixedly installed on the inner wall of the right side of the machine body shell. The inner air guide pipe and the outer air guide pipe are located on the inner and outer sides of the air inlet, respectively. The left end of the outer air guide pipe is hinged with a plurality of circumferentially evenly distributed diverter plates. A driving component for driving the diverter plates to flip is installed on the outer air guide pipe.

[0008] In one possible implementation, a rotor located inside the housing is fixedly mounted on the rotating shaft, a stator is fixedly mounted on the inner ring wall of the housing, the rotor is located inside the stator, and a plurality of heat dissipation fins are mounted on the outer ring wall of the housing.

[0009] In one possible implementation, the enclosure assembly includes gear discs rotatably mounted on both the left and right ends of the housing, the gear discs having a plurality of circumferentially evenly distributed ventilation holes, a drive shaft rotatably mounted on the bottom of the housing, a drive gear one mounted on both the left and right ends of the drive shaft, the drive gear one meshing with the corresponding gear disc, and an electromagnetic telescopic rod one for driving the rotation of the right gear disc mounted on the rear air guide cover.

[0010] In one possible implementation, the temperature detection assembly includes a temperature sensor one mounted on the rotor and a temperature sensor two mounted on the stator. A controller is mounted on the housing, and the controller is electrically connected to the temperature sensor one, the temperature sensor two, and the electromagnetic telescopic rod one, respectively. The temperature sensor one and the temperature sensor two detect the temperature of the rotor and the stator, respectively, and output electrical signals to the controller. The controller analyzes the electrical signals from the temperature sensor one and the temperature sensor two and sends control signals to the electromagnetic telescopic rod one.

[0011] In one possible implementation, the adjusting component includes a partition plate fixedly installed between the inner ring wall of the rear air guide shroud and the outer ring wall of the machine body shell. The partition plate has a plurality of circumferentially evenly distributed dampers. A sealing plate for controlling the opening and closing of the dampers is rotatably installed on the partition plate. A transmission gear II is installed on the sealing plate, and the transmission gear II meshes with a gear turntable.

[0012] In one possible implementation, the inner and outer air ducts are coaxial, and a flow guide ring is fixedly connected to the left side of the outer air duct. The flow guide ring is shaped like a flared mouth with the larger end facing left. The flow guide plate is divided into inner and outer rings, which are spaced apart.

[0013] In one possible implementation, the drive assembly includes a movable ring that is slidably mounted on the outer ring wall of the outer air duct. A fixed rod is fixedly connected to the side of the air guide plate away from the central axis of the outer air duct. Several linkage rods are hinged to the outer ring wall of the outer air duct and evenly distributed in the circumference. The left end of the linkage rod is hinged to the fixed rod. An electromagnetic telescopic rod II for driving the movable ring to move left and right is installed on the inner wall of the outer casing.

[0014] In one possible implementation, a sound-absorbing component is also included, comprising a double-sleeved tube fixedly installed on the left and right inner walls of the outer casing, with the air outlet and air inlet located between the corresponding layers of the double-sleeved tube, and sound-absorbing cotton installed between the layers of the double-sleeved tube, the sound-absorbing cotton having ventilation channels for airflow inside.

[0015] The beneficial effects of this invention are as follows: 1. By optimizing the airflow channels inside and outside the casing, when the temperature inside the casing is low, the air outlet and air inlet are closed, while the airflow channel at the edge of the rear air guide is open. Air flows in from the air inlet at the center of the rear air guide and then flows out from the airflow channel at the edge of the rear air guide, which can cool and dissipate heat from the outer wall of the casing. Since the air outlet and air inlet are closed, they can also provide sound insulation and dust protection. When the temperature inside the casing is too high, the sealing component controls the air outlet and air inlet to open, while the adjusting component controls the airflow channel at the edge of the rear air guide to close. Air enters the interior of the casing from the air inlet and can directly cool the interior of the casing. Then, the air inside the casing enters the inner side of the front air guide from the air outlet to the left and flows out from the airflow channel at the edge of the front air guide, which cools and dissipates heat from the outer wall of the casing, achieving simultaneous internal and external heat dissipation and improving heat dissipation efficiency.

[0016] 2. This invention adjusts the direction of airflow through a deflector plate. When the stator temperature is high, the drive assembly rotates the deflector plate away from the central axis of the casing, causing the airflow to flow closer to the stator and improving the stator's cooling effect. When the rotor temperature is high, the drive assembly rotates the deflector plate closer to the central axis of the casing, causing the airflow to flow closer to the rotor and improving the rotor's cooling effect. When the rotor and stator temperatures are equal, the deflector plate rotates to a horizontal position, allowing airflow to flow between the rotor and stator, enabling balanced cooling of the central and edge parts of the casing. By adjusting the airflow direction, targeted heat dissipation can be achieved inside the casing, improving the heat dissipation effect, reducing motor temperature rise, and reducing energy loss.

Detailed Implementation

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Please see Figure 1 - Figure 10An energy-saving motor with optimized air duct includes a body component 1. The body component 1 includes a housing 11 and a rotating shaft 12 rotatably mounted on the central axis of the housing 11 and extending through the left and right sides. The left and right ends of the housing 11 are respectively provided with circumferentially evenly distributed air outlets 15 and air inlets 16.

[0030] The heat dissipation component 2 includes a fan 21 fixedly installed on the right end of the rotating shaft 12, a front air guide shroud 22 and a rear air guide shroud 23 respectively installed on the left and right ends of the housing 11, the fan 21 being located inside the rear air guide shroud 23, a sealing component 24 installed on the housing 11 for controlling the opening and closing of the air outlet 15 and the air inlet 16, and a temperature detection component 25 for detecting the internal temperature of the housing 11. An air inlet is provided at the center of the rear air guide shroud 23.

[0031] Adjustment component 3, installed on the rear air guide shroud 23, is used to control the opening and closing of the air duct at the edge of the rear air guide shroud 23. When the air outlet 15 and the air inlet 16 are opened, the air duct at the edge of the rear air guide shroud 23 is closed.

[0032] The guiding component 4 includes an inner air guide duct 41 and an outer air guide duct 42 fixedly installed on the inner wall of the right side of the outer casing 11. The inner air guide duct 41 and the outer air guide duct 42 are located on the inner and outer sides of the air inlet 16, respectively. The left end of the outer air guide duct 42 is hinged with a number of circumferentially evenly distributed guide plates 44. A driving assembly 45 for driving the guide plates 44 to flip is installed on the outer air guide duct 42.

[0033] A rotor 13 is fixedly mounted on the shaft 12 and located inside the housing 11. A stator 14 is fixedly mounted on the inner ring wall of the housing 11. The rotor 13 is located inside the stator 14. Several heat dissipation fins 111 are installed on the outer ring wall of the housing 11.

[0034] In practical use, when the temperature inside the casing 11 is low, the air outlet 15 and air inlet 16 are closed, while the air duct at the edge of the rear air guide shroud 23 is open. When the shaft 12 drives the fan 21 to rotate, air flows in from the air inlet at the center of the rear air guide shroud 23 and then flows out from the air duct at the edge of the rear air guide shroud 23, causing the airflow around the outer ring wall of the casing 11 to flow from right to left, which can cool and dissipate heat from the outer wall of the casing 11. The temperature inside the casing 11 is dissipated into the air through the heat dissipation fins 111. Since the air outlet 15 and air inlet 16 are closed, they can play a role in sound insulation and dust prevention.

[0035] When the temperature inside the casing 11 is too high, the sealing component 24 controls the air outlet 15 and the air inlet 16 to open, while the adjusting component 3 controls the air duct at the edge of the rear air guide shroud 23 to close. When the rotating shaft 12 drives the fan 21 to rotate, air flows into the inner side of the rear air guide shroud 23 from the air inlet in the center of the rear air guide shroud 23, and then enters the interior of the casing 11 through the air inlet 16, which can directly cool the interior of the casing 11. Then, the air inside the casing 11 enters the inner side of the front air guide shroud 22 from the air outlet 15 to the left, and then flows out from the air duct at the edge of the front air guide shroud 22, which drives the airflow around the outer ring wall of the casing 11 to flow from left to right, cooling the outer wall of the casing 11. By optimizing the airflow duct, simultaneous internal and external heat dissipation is achieved, improving the efficiency of heat dissipation.

[0036] When the air outlet 15 and air inlet 16 are open, and the stator 14 is at a high temperature, the drive assembly 45 drives the air intake plate 44 to rotate away from the central axis of the housing 11, thus widening the opening formed by the air intake plate 44. This allows airflow to flow closer to the stator 14, improving the cooling effect of the stator 14. When the rotor 13 is at a high temperature, the drive assembly 45 drives the air intake plate 44 to rotate closer to the central axis of the housing 11, thus narrowing the opening formed by the air intake plate 44. This allows airflow to flow closer to the rotor 13, improving the cooling effect of the rotor 13. When the temperatures of the rotor 13 and stator 14 are the same, the air intake plate 44 rotates to a horizontal position, allowing airflow to flow between the rotor 13 and stator 14. This enables even cooling of the central and edge parts of the housing 11. By adjusting the airflow direction, targeted heat dissipation can be achieved inside the housing 11, improving the heat dissipation effect, reducing motor temperature rise, and reducing energy loss.

[0037] Please see Figure 2 , Figure 3 and Figure 4 The sealing assembly 24 includes a gear turntable 241 rotatably mounted on both the left and right ends of the outer casing 11. The gear turntable 241 has several circumferentially evenly distributed ventilation holes 242. A drive shaft 243 is rotatably mounted on the bottom of the outer casing 11. A drive gear 244 is mounted on both the left and right ends of the drive shaft 243. The drive gear 244 meshes with the corresponding gear turntable 241. An electromagnetic telescopic rod 245 for driving the right gear turntable 241 to rotate is mounted on the rear air guide shroud 23.

[0038] In practical use, initially, the temperature of the rotor 13 and stator 14 is below the set threshold. At this time, the ventilation hole 242 is completely offset from the exhaust hole 15 and the intake hole 16. The left and right gear discs 241 then seal the exhaust hole 15 and the intake hole 16 respectively, keeping them closed, thus providing sound insulation and dust prevention. When the temperature of the rotor 13 or stator 14 exceeds the set threshold, the electromagnetic telescopic rod 245 drives the right side... The gear turntable 241 rotates counterclockwise. The gear turntable 241 on the right side drives the gear turntable 241 on the left side to rotate synchronously through the transmission shaft 243 until the ventilation holes 242 on the left and right sides coincide with the air outlet 15 and the air inlet 16 respectively. In this way, the outside air can flow into the outer casing 11 from the air inlet 16 under the action of the fan 21, and the air inside the outer casing 11 is discharged to the left from the air outlet 15, which can improve the cooling effect on the rotor 13 and stator 14 inside the outer casing 11.

[0039] When the temperature of rotor 13 and stator 14 drops below the set threshold, electromagnetic telescopic rod 245 drives the right gear turntable 241 to rotate clockwise. The right gear turntable 241 drives the left gear turntable 241 to rotate through the transmission shaft 243 until the ventilation hole 242 is completely offset from the air outlet 15 and the air inlet 16.

[0040] Please see Figure 2 and Figure 4 The temperature detection assembly 25 includes a temperature sensor 251 mounted on the rotor 13 and a temperature sensor 252 mounted on the stator 14. A controller 253 is mounted on the housing 11. The controller 253 is electrically connected to the temperature sensor 251, the temperature sensor 252 and the electromagnetic telescopic rod 245. The temperature sensor 251 and the temperature sensor 252 detect the temperature of the rotor 13 and the stator 14 respectively and output electrical signals to the controller 253. The controller 253 analyzes the electrical signals from the temperature sensor 251 and the temperature sensor 252 and sends control signals to the electromagnetic telescopic rod 245.

[0041] In practical use, temperature sensors 251 and 252 are used to detect the temperature of rotor 13 and stator 14 respectively. When the temperature of rotor 13 and stator 14 is lower than the set threshold, temperature sensors 251 and 252 transmit signals to controller 253. Controller 253 controls electromagnetic telescopic rod 245 to be in a retracted state. At this time, ventilation hole 242 is completely offset from air outlet 15 and air inlet 16. When the temperature of rotor 13 or stator 14 is higher than the set threshold, temperature sensors 251 or 252 transmit signals to controller 253. Controller 253 controls electromagnetic telescopic rod 245 to be in an extended state. At this time, ventilation hole 242 coincides with air outlet 15 and air inlet 16, allowing outside air to enter the outer casing 11 through air inlet 16 to directly cool rotor 13 and stator 14.

[0042] Please see Figure 2 , Figure 3 and Figure 5 The adjusting component 3 includes a partition 31 fixedly installed between the inner ring wall of the rear air guide shroud 23 and the outer ring wall of the outer shell 11. The partition 31 has several circumferentially evenly distributed air dampers 32. A sealing plate 33 for controlling the opening and closing of the air dampers 32 is rotatably installed on the partition 31. A transmission gear 34 is installed on the sealing plate 33. The transmission gear 34 meshes with the gear turntable 241.

[0043] In practical use, when the ventilation hole 242 is completely offset from the air outlet 15 and the air inlet 16, the damper 32 is in the open state. At this time, the airflow inside the rear air guide shroud 23 can flow to the left through the damper 32 towards the heat dissipation fin 111, driving the airflow around the heat dissipation fin 111 and improving the heat dissipation effect of the heat dissipation fin 111.

[0044] When the electromagnetic telescopic rod 245 drives the right gear turntable 241 to rotate counterclockwise, the right gear turntable 241 drives the transmission gear 34 to rotate. The transmission gear 34 drives the sealing plate 33 to rotate 90 degrees, so that the sealing plate 33 closes the damper 32. In this way, the airflow entering the inside of the rear air guide shroud 23 cannot flow to the heat dissipation fins 111 through the damper 32. This allows the airflow inside the rear air guide shroud 23 to be concentrated and enter the inside of the outer casing 11 through the air inlet 16, ensuring the cooling effect inside the outer casing 11.

[0045] Please see Figure 2 , Figure 3 and Figure 6 The inner air duct 41 and the outer air duct 42 are coaxial. A flow guide ring 43 is fixedly connected to the left side of the outer air duct 42. The flow guide ring 43 is in the shape of a flared mouth with the larger end facing left. The flow guide plate 44 is divided into inner and outer rings, and the inner and outer rings of flow guide plate 44 are arranged at intervals.

[0046] Please see Figure 2 , Figure 6 - Figure 9 The drive assembly 45 includes a movable ring 451 that is slidably mounted on the outer ring wall of the outer air duct 42. A fixed rod 452 is fixedly connected to the side of the flow plate 44 away from the central axis of the outer air duct 42. Several linkage rods 453 are hinged to the outer ring wall of the outer air duct 42 and evenly distributed in the circumference. The left end of the linkage rod 453 is hinged to the fixed rod 452. An electromagnetic telescopic rod 454 for driving the movable ring 451 to move left and right is installed on the inner wall of the outer casing 11. The electromagnetic telescopic rod 454 is electrically connected to the controller 253.

[0047] In practical use, initially, the flow-guiding plate 44 is in a horizontal state. When the electromagnetic telescopic rod 454 drives the movable ring 451 to move to the right, the movable ring 451 pulls the linkage rod 453 to move to the right. The linkage rod 453 pulls the fixed rod 452 and the flow-guiding plate 44 to rotate away from the central axis of the outer shell 11, thus expanding the opening formed by the flow-guiding plate 44. The airflow can then flow along the flow-guiding plate 44 away from the central axis of the outer shell 11. Conversely, when the electromagnetic telescopic rod 454 drives the movable ring 451 to move to the left, the movable ring 451 pushes the linkage rod 453 to move to the left. The linkage rod 453 pushes the fixed rod 452 and the flow-guiding plate 44 to move closer to the central axis of the outer shell 11, thus narrowing the opening formed by the flow-guiding plate 44.

[0048] Airflow entering the housing 11 through the air inlet 16 flows to the left between the inner air duct 41 and the outer air duct 42. The airflow is guided by the airflow ring 43, causing it to flow towards the airflow plate 44. When the left end of the airflow plate 44 is tilted away from the central axis of the housing 11, the airflow can flow along the airflow plate 44 away from the central axis of the housing 11, allowing the airflow to directly blow on the stator 14 for heat dissipation. When the airflow plate 44 is in a horizontal state, the airflow flows to the left along the airflow plate 44, simultaneously cooling the rotor 13 and the stator 14. When the left end of the airflow plate 44 is tilted towards the central axis of the housing 11, the airflow can flow along the airflow plate 44 towards the central axis of the housing 11, allowing the airflow to directly blow on the rotor 13 for heat dissipation.

[0049] Please see Figure 2 , Figure 3 and Figure 10 It also includes a sound-absorbing component 5, which includes a double sleeve 51 fixedly installed on the left and right inner walls of the outer casing 11. The air outlet 15 and the air inlet 16 are respectively located between the interlayers of the corresponding double sleeve 51. Sound-absorbing cotton 52 is installed between the interlayers of the double sleeve 51. The sound-absorbing cotton 52 has a ventilation channel 53 for air flow inside.

[0050] In practical use, sound-absorbing cotton 52 is installed at one end of the air outlet 15 and air inlet 16 near the inside of the outer casing 11. When the air outlet 15 and air inlet 16 are opened, the gas can flow through the ventilation duct 53. The sound-absorbing cotton 52 and the ventilation duct 53 can absorb and reduce noise, thereby reducing the impact of noise generated inside the outer casing 11 on the outside world when the air outlet 15 and air inlet 16 are open.
