Description

Technical Field

[0001] The present invention relates to the technical field of waterproof and dustproof, and in particular to a waterproof and dustproof high-performance permanent magnet synchronous motor. Background Art

[0002] A high-performance permanent magnet synchronous motor is an AC motor that uses rare earth permanent magnets to establish a magnetic field and in which the stator winding rotates synchronously with the rotor magnetic field. Its core advantages lie in high efficiency, high power density and precise control. It is widely used in electric vehicles, industrial robots and other fields.

[0003] When water enters the motor, the winding insulation layer will age and crack, resulting in a decrease in insulation resistance. When water adheres to the motor surface or internal heat dissipation channels, it may hinder heat dissipation, further accelerating insulation aging and permanent magnet demagnetization. When dust enters the motor, it will generate friction with the rotation of components such as the rotor and bearings, causing mechanical wear. Therefore, permanent magnet synchronous motors must be waterproof and dustproof.

[0004] The existing technologies for the above problems are mainly achieved through protective structure design, sealing technology application, material selection and auxiliary protection measures. However, waterproofing mainly relies on passive blocking. Surface moisture is difficult to remove quickly and is easy to penetrate into the interior. After water enters the body, there is a lack of effective collection and discharge mechanism. Water accumulation causes failures. Dust protection is mostly static protection. Internally deposited dust is difficult to remove, and the mixture of dust and residual water will aggravate component corrosion. At the same time, the front and rear end protection is unbalanced, and the gaps at the rear end are prone to water seepage and dust accumulation. There is a lack of a closed-loop design from external protection to internal drainage, resulting in poor waterproof and dustproof effects and shortened motor life.

[0005] Therefore, we propose a waterproof and dustproof high-performance permanent magnet synchronous motor to solve the above problems. Summary of the Invention

[0022] The effect achieved by the entire embodiment 1 is as follows: when external moisture contacts the protective mechanism 100, the first wind system 107 generates airflow to drive the first water-repelling roller 106, accelerating the evaporation of surface water vapor to enhance the primary waterproof effect; the first water-repelling roller 106 rotates at high speed to generate centrifugal force, quickly removing moisture attached to the surface, reducing the risk of infiltration, and the residual moisture that has not been completely removed enters the multi-layer waterproof sealed structure 108 at the rear, and its multi-layer sealing design can prevent moisture penetration and provide installation space for the evaporation heating wire 117; then the evaporation heating wire 117 is powered on and heated, evaporating the residual moisture to completely eliminate surface moisture and enhance the waterproof effect, and the heat insulation protective plate 118 blocks the high temperature of the evaporation heating wire 117 from being transmitted to the motor body 5, and at the same time physically isolates the external environment from the internal components; the limiting ring 115 limits the evaporation heating wire 117 7 radial displacement, preventing it from shaking and contacting other components; the limiting mounting plate 116 fixes the axial position of the heating wire to ensure the stability of the heating area; the mounting fixture 114 rigidly connects the shaft sleeve and the protective plate to enhance the structural stability; the shaft mounting sleeve 112 provides rotation support for the power transmission shaft 4; the shaft sealing structure 113 prevents moisture from penetrating along the shaft, strengthens the sealing of the connection between the power transmission shaft 4 and the heat insulation protective plate 118, and cooperates with the isolation effect of the heat insulation protective plate 118 itself to form a front-end multi-layer protection barrier, which effectively solves the problem of external moisture penetrating into internal components and the high temperature during heating and dehumidification that may cause damage to core components, thereby ensuring the stable operation of each component during operation, and solving the problems of functional failure or malfunction due to component displacement and shaking, as well as the limited effect of a single protection measure and insufficient overall protection capability.

[0023] Example 2, according to Figure 1-Figure 3 and Figure 7-Figure 8 As shown. A front end cover 101 is connected to one side of the outer wall of the heat insulation protection plate 118. A set of front end cover vent holes 103 are formed on one side of the outer wall of the front end cover vent holes 103.

A set of mounting ears 102 are mounted on one side of the outer wall of the front end cover 101. A coupling mounting member 105 is formed and mounted in the middle of one side of the outer wall of the set of front end cover fixing brackets 104. The inner wall of the coupling mounting member 105 is rotatably connected to the power transmission shaft 4. A set of casing heat dissipation plates 202 and casing mounting bolts 203 are respectively installed on the outer wall of the fuselage shell 201. A set of motor base support frames 204 are installed at the bottom of the outer wall of the fuselage shell 201. One side of the outer wall of the set of motor base support frames 204 is connected to a motor mounting base 205. A drainage box 206 is mounted on the upper portion of one side of the outer wall of the motor mounting base 205. The drainage box 206 is used to drain moisture from the interior of the fuselage shell 201. A water collection box 211 is mounted on the outer wall of the fuselage shell 201 and located above the motor mounting base 205. A sealed, leak-proof fixing member 207 is mounted on one side of the outer wall of the water collection box 211 and the drainage box 206. A water pipe 208 is connected between a set of sealed and leak-proof fixing parts 207. A water pump 209 is installed on the outer wall of the water pipe 208. A power system 210 is installed on one side of the outer wall of the water pump 209. A limited water collection tank 212 is installed at the lower part of the inner wall of the fuselage shell 201. A set of through grooves 213 are opened at the lower part of the inner wall of the limited water collection tank 212. The through grooves 213 are connected to the water collection box 211. A set of annular guide rails 214 are opened on the inner wall of the fuselage shell 201. The drainage box 206, water pipe 208, water pump 209, etc. constitute a drainage system to drain accumulated water. The inner wall of the annular guide rail 214 is slidably connected with a brush plate 215, and the outer wall of the brush plate 215 is installed with a group of brush heads 216. A group of brush heads 216 are used to collect moisture inside the fuselage shell 201 and transport it to the through groove 213 in the lower end limit water collection tank 212. One side of the outer wall of the fuselage shell 201 is connected with a rear end cover 301, and one side of the outer wall of the rear end cover 301 is installed with a rear end cover sealing structure 302. One side of the outer wall of the rear end cover sealing structure 302 is rotatably connected with a group of second water-shedding rollers 303, and a second wind power system 304 is rotatably connected between a group of second water-shedding rollers 303. The annular guide rail 214, the brush plate 215, and the brush heads 216 can clean the interior to ensure that the interior of the motor is clean and dry. The second water-shedding rollers 303 and the second blades 304 assist in water shedding and dust removal, keep the interior of the motor clean, and prevent dust and moisture from affecting the operation of the motor.

[0024] The effect achieved by the entire embodiment 2 is as follows: when moisture penetrates into the interior of the fuselage shell 201, the annular guide rail 214 provides a sliding track for the brush plate, guiding the brush plate 215 to make a circular motion, driving the brush plate 215 to drive the brush head 216 to move, thereby cleaning the inner wall of the fuselage shell 201, and making a circular motion inside the fuselage shell 201, driving the brush head 216 to clean the inner wall of the fuselage shell 201, collecting moisture and dust. Since the fuselage shell 201 is a closed cavity, the directional airflow generated by the operation of the second wind system 304 is from the rear end cover The water diffuses toward the middle of the fuselage, and inevitably acts on the brush plate 215 which is slidably connected to the annular guide rail 214. The brush plate 215 needs to be installed with a brush head 216, which has a sufficient force-bearing area. The airflow thrust directly pushes the brush plate 215 to make a circular motion along the annular guide rail 214, collects it to the designated position to clean the inner wall of the fuselage shell 201, collects the water into the limited water collecting groove 212 to collect the water inside the fuselage, and guides the water to flow into the through groove 213. The water flows into the water collecting box 211 through the through groove 213 inside the limited water collecting groove 212, and passes through the water pipe 20 8 is transported to the drainage box 206, and the water in the water collection box 211 is transported through the water pipe 208 to form a drainage channel. The water leakage is prevented by the sealed leak-proof fixing part 207, and the sealed interface is transported to the drainage box 206 to discharge the water inside the fuselage to the outside of the motor, completing the drainage process, and finally discharged to the outside of the motor to form a closed-loop waterproof system; the second wind system 304 blows up the dust deposited inside, and at the same time drives the second water-removing roller 303 to rotate, assisting in removing the water infiltrated from the rear end and driving the second water-removing roller 303 to remove the water infiltrated from the gap at the rear end. A small amount of moisture is thrown off, and the air is stirred to enhance the dust removal effect. On the one hand, the dust that may be deposited inside is blown to the inside of the fuselage shell 201 through the airflow, and on the other hand, a small amount of moisture that penetrates from the gap at the rear end is thrown off. In the process of collecting moisture, the brush plate 215 and the brush head 216 simultaneously clean the internal dust blown in by the second wind system 304, which effectively solves the problems of the inability to effectively remove the moisture that has penetrated into the fuselage and the easy residual water, the difficulty in thoroughly cleaning the dust deposition, and the weak protection against moisture and dust infiltration at the rear end.

[0025] The entire device operates as follows: After the motor starts, the protective mechanism 100 enters operation. The front cover 101 is secured to the device via mounting ears 102. Ventilation holes 103 on its surface allow for internal and external air circulation, ensuring heat dissipation. The front cover mounting bracket 104, in conjunction with the coupling mounting member 105, provides stable rotational support for the power transmission shaft 4, ensuring efficient power output from the motor body 5.When external moisture contacts the protective mechanism 100, the first wind system 107 starts synchronously, driving a set of first water-removing rollers 106 to rotate at high speed, and using centrifugal force to quickly remove surface water; the residual moisture that has not been completely removed will enter the rear multi-layer waterproof and sealed structure 108, and then the evaporation heating wire 117 inside the multi-layer waterproof and sealed structure 108 is energized and heated to evaporate and remove the residual moisture. In this process, the heat insulation protective plate 118 isolates the evaporation heating wire 117 from the motor body 5, thereby protecting the motor body 5 from the influence of high temperature. The limiting ring 115 and the limiting mounting plate 116 fix the position of the evaporation heating wire 117, and the fixing member 114, the shaft mounting sleeve 112 and the shaft are installed. The sealing structure 113 strengthens the sealing of the connection between the power transmission shaft 4 and the heat insulation protection plate 118, and cooperates with the isolation effect of the heat insulation protection plate 118 itself to form a front-end multi-layer protection barrier; while the protection mechanism 100 is working, the waterproof mechanism 200 enters a continuous operation state, and the fuselage shell 201 serves as the main protective shell of the motor, which is fastened by the shell mounting bolts 203. The shell heat sink 202 on its surface dissipates the heat generated by the motor operation, and the motor base support frame 204 and the motor mounting base 205 jointly support the fuselage to ensure overall stability. The multi-layer waterproof and sealed structure 108 further enhances the sealing of the connection between the fuselage shell 201 and the protection mechanism, and connects the fixing frame 109, the support beam 110 and the support The supporting member 111 strengthens the internal structure to prevent the sealing function from being damaged due to vibration. If water accidentally penetrates into the fuselage shell 201, the annular guide rail 214 drives the brush plate 215 to make a circular motion inside the fuselage shell 201, driving the brush head 216 to clean the inner wall of the fuselage shell 201, and collects the water into the limited water collection groove 212. The water flows into the water collection box 211 through the through groove 213 inside the limited water collection groove 212; then the power system 210 drives the water pump 209 to transport the water in the water collection box 211 through the water pipe 208 and the sealed interface of the sealed leak-proof fixing member 207 to the drainage box 206, and finally discharges it to the outside of the motor body 5, forming a closed-loop waterproof system. During the entire operation of the motor, the dust removal mechanism 300 is synchronized The rear end cover 301 is tightly connected to the fuselage shell 201 through the rear end cover sealing structure 302, blocking the intrusion path of external dust; the second wind system 304 drives the second water-removing roller 303 to rotate, on the one hand, the dust deposited inside is blown to the inside of the fuselage shell 201 through the airflow, and on the other hand, a small amount of water seeping in from the rear end gap is removed. In the process of collecting water, the brush plate 215 and the brush head 216 simultaneously clean the internal dust blown in by the second wind system 304 to prevent dust from adhering to the surface of the motor body 5 and affecting heat dissipation or causing component wear. Through the above-mentioned coordinated operation, the protection, waterproofing and dust removal mechanisms form an all-round protection system to ensure that the motor continues to operate efficiently in a complex environment.
