Description

Technical Field

[0001] This utility model relates to the field of three-phase induction motors, and in particular to a heat dissipation component for three-phase induction motors. Background Technology

[0002] Three-phase induction motors are a type of electric motor widely used in industry, agriculture, and home appliances, playing a particularly important role in high-power drives. Their working principle is based on electromagnetic induction, and they belong to the category of AC motors.

[0003] Existing technologies, such as the utility model patent with publication number CN219107251U, disclose an electric motor. This patent employs a stator and a rotor. The stator includes a housing, a stator core disposed within the housing, and a stator winding wound around the stator core. The motor further includes a busbar unit located within the housing and positioned on one axial side of the stator core. The busbar unit includes: an insulating retainer; and multiple busbars supported by the insulating retainer. Each busbar includes a first end, a second end, and a main body connecting the first end and the second end. The first end of the busbar protrudes radially outward from the insulating retainer, and the second end of the busbar protrudes axially away from the insulating retainer. The first end of the busbar has a first operating space and a second operating space on its circumferential sides, respectively, to enable automated electrical connection between the first end of the busbar and the output terminal of the stator winding.

[0004] The inventors discovered in daily use that existing three-phase induction motors have low heat dissipation efficiency. During prolonged operation, the motor easily accumulates heat, leading to excessively high temperatures. High temperatures increase the motor's resistive losses (such as stator and rotor resistance), resulting in higher power loss. This not only affects motor efficiency but also leads to energy waste. Overheating accelerates the aging of insulation materials, especially the stator and rotor insulation layers. Prolonged operation at high temperatures can damage these insulation layers, leading to short circuits or insulation failures. Consequently, the motor's lifespan is significantly shortened. Excessive temperatures cause uneven thermal expansion of internal components, resulting in wear or jamming of mechanical parts. Bearings may also experience poor lubrication due to overheating, leading to premature damage.

[0005] This application provides another technical solution to this technical problem, aiming to provide those skilled in the art with multiple options for solving the problem. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as poor heat dissipation in three-phase induction motors.

[0007] To solve the above technical problems, this utility model provides a heat dissipation assembly for a three-phase induction motor, comprising: a connecting base, a motor body mounted on the upper end of the connecting base, a junction box mounted on the upper surface of the motor body, a drive shaft mounted on the output end of the motor body, a heat dissipation structure provided on the side of the connecting base away from the drive shaft, the heat dissipation structure including a connecting ring, the connecting ring being fixedly connected to the motor body, a plurality of holes being formed in the inner wall of the connecting ring, a housing being slidably connected to the arc surface of the connecting ring, and a plurality of holes being fixedly connected to the inner wall of the housing. A connecting rod is slidably connected to a hole. A washer is fixedly connected to one end of each connecting rod that is close to each other. A cleaning ring is fixedly connected to the arc surface of the connecting rod. A connecting rod is fixedly connected to the side of the motor body near the outer casing. A connecting groove is provided on the inner wall of the outer casing, and the connecting groove is slidably connected to the connecting rod. A slip ring is slidably connected to the arc surface of the connecting rod, and the slip ring is fixedly connected to the outer casing. A screw is threadedly connected to the arc surface of the slip ring, and the screw abuts against the connecting rod. Several heat dissipation holes are provided on the inner wall of the outer casing.

[0008] The aforementioned components achieve the following effects: During normal use, the heat generated by the motor is dissipated through the heat dissipation holes. When increased heat dissipation efficiency is required, the screw is rotated to loosen it, separating the screw from the slide rod. Then, the slip ring is pulled to move, causing the slip ring to move the outer casing. The outer casing and the slip ring slide on the arc surface of the connecting rod. Then, the outer casing moves on the connecting ring, which in turn moves the connecting rod. The connecting rod then moves the washer and cleaning ring. After moving to the appropriate position, the cleaning ring cleans the holes. After moving to the appropriate position, the screw is tightened to engage and fix the connection rod, allowing the heat dissipation holes and openings to dissipate heat.

[0009] Preferably, the outer casing has a plurality of auxiliary grooves on its arc surface, and the plurality of auxiliary grooves are evenly distributed on the outer casing.

[0010] The effect achieved by the above components is that the auxiliary groove can increase the friction between the hand and the outer shell, preventing slippage when pulling the outer shell.

[0011] Preferably, a plurality of sliding rods are fixedly connected to the arc surface of the connecting rod, and the plurality of sliding rods are evenly distributed on the connecting rod.

[0012] The effect achieved by the above components is that the slide bar can limit the movement of the slip ring, preventing the slip ring from shifting during use and improving the stability of the slip ring's sliding.

[0013] Preferably, a protective sleeve, which is a rubber sleeve, is fixedly connected to the inner wall of the outer shell.

[0014] The effect achieved by the above components is that the protective pad can protect the connecting ring and prevent it from excessive wear during use.

[0015] Preferably, the connecting ring has a circular cross-section and is made of stainless steel.

[0016] The effects achieved by the above components are as follows: the stainless steel material can increase the service life of the connecting ring, prevent the connecting ring from deforming during use, and the high melting point of stainless steel will not be affected by the heat of the motor.

[0017] Preferably, the connecting rod has a circular cross-section, and several connecting rods are evenly distributed on the outer shell. The connecting rod is made of aluminum.

[0018] The effect achieved by the above components is that the aluminum rod has high thermal conductivity, which can increase the heat dissipation efficiency of the holes.

[0019] Compared with related technologies, the heat dissipation component for a three-phase induction motor provided by this utility model has the following advantages:

[0020] By designing a heat dissipation structure, we can address the issue that existing three-phase induction motors suffer from low heat dissipation efficiency. During prolonged operation, these motors tend to accumulate heat, leading to excessively high temperatures. High temperatures increase resistance losses (such as stator and rotor resistance), resulting in higher power losses. This not only affects motor efficiency but also wastes energy. Overheating accelerates the aging of insulation materials, especially the stator and rotor insulation varnish. Prolonged operation at high temperatures can damage these insulation layers, leading to short circuits or insulation failures. Consequently, the motor's lifespan is significantly shortened. Excessive temperatures also cause uneven thermal expansion of internal components, resulting in wear or jamming of mechanical parts. Bearings may experience poor lubrication due to overheating, leading to premature damage. This device allows for adjustable housing positions, facilitating improved internal heat dissipation efficiency. This not only enhances heat dissipation but also slows down motor aging.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5 The present invention provides a heat dissipation assembly for a three-phase induction motor, comprising: a connecting base 1, a motor body 2 mounted on the upper end of the connecting base 1, a junction box 3 mounted on the upper surface of the motor body 2, a drive shaft 4 mounted on the output end of the motor body 2, and a heat dissipation structure 5 provided on the side of the connecting base 1 away from the drive shaft 4.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5The heat dissipation structure 5 includes a connecting ring 501, which is fixedly connected to the motor body 2. The inner wall of the connecting ring 501 has several holes 502. A housing 508 is slidably connected to the arc surface of the connecting ring 501. Several connecting rods 511 are fixedly connected to the inner wall of the housing 508. The connecting rods 511 are slidably connected to the holes 502. A gasket 510 is fixedly connected to one end of each connecting rod 511 that is close to the other. A cleaning ring is fixedly connected to the arc surface of the connecting rod 511. 512, A connecting rod 503 is fixedly connected to the side of the motor body 2 near the outer casing 508. A connecting groove 514 is provided on the inner wall of the outer casing 508. The connecting groove 514 is slidably connected to the connecting rod 503. A slip ring 505 is slidably connected to the arc surface of the connecting rod 503. The slip ring 505 is fixedly connected to the outer casing 508. A screw 506 is threadedly connected to the arc surface of the slip ring 505. The screw 506 abuts against the connecting rod 503. Several heat dissipation holes 507 are provided on the inner wall of the outer casing 508. During normal use, the heat generated by the motor is dissipated through the heat dissipation hole 507. When it is necessary to increase the heat dissipation efficiency, the screw 506 is rotated to loosen it, the screw 506 is separated from the slide rod 504, and then the slip ring 505 is pulled to move it. The slip ring 505 drives the housing 508 to move. The housing 508 and the slip ring 505 slide on the arc surface of the connecting rod 503. Then the housing 508 moves on the connecting ring 501. The connecting ring 501 drives the connecting rod 511 to move. The connecting rod 511 drives the washer 510 and the cleaning ring 512 to move. After moving to the appropriate position, the cleaning ring 512 cleans the hole 502. After moving to the appropriate position, the screw 506 is turned to abut and fix it to the connecting rod 503. The heat dissipation hole 507 and the hole 502 dissipate heat. The arc surface of the housing 508 is provided with several auxiliary grooves 509, which are evenly distributed on the housing 508. The auxiliary groove 509 increases the friction between the hand and the outer casing 508, preventing slippage when pulling the outer casing 508. Several sliding rods 504 are fixedly connected to the arc surface of the connecting rod 503, and these sliding rods 504 are evenly distributed on the connecting rod 503. The sliding rods 504 limit the movement of the slip ring 505, preventing it from shifting during use and improving the stability of the slip ring 505's sliding. A protective sleeve 513, made of rubber, is fixedly connected to the inner wall of the outer casing 508. A protective pad protects the connecting ring 501, preventing excessive wear during use. The connecting ring 501 has an annular cross-section and is made of stainless steel. The stainless steel material increases the service life of the connecting ring 501, preventing deformation during use. Furthermore, the high melting point of stainless steel means it is unaffected by motor heat. The connecting rod 511 has a circular cross-section, and several connecting rods 511 are evenly distributed on the outer casing 508. The connecting rods 511 are made of aluminum. Aluminum rods have high thermal conductivity, which increases the heat dissipation efficiency of the holes 502.

[0031] The working principle of the heat dissipation component for a three-phase induction motor provided by this utility model is as follows: During normal use, the heat generated by the motor is dissipated through the heat dissipation hole 507. When it is necessary to increase the heat dissipation efficiency, the screw 506 is rotated to loosen it, separating the screw 506 from the slide rod 504. Then, the slip ring 505 is pulled to move, and the slip ring 505 drives the outer shell 508 to move. The outer shell 508 and the slip ring 505 slide on the arc surface of the connecting rod 503. Then, the outer shell 508 moves on the connecting ring 501, and the connecting ring 501 drives the connecting rod 511 to move. The connecting rod 511 drives the washer 510 and the cleaning ring 512 to move. After moving to the appropriate position, the cleaning ring 512 cleans the hole 502. After moving to the appropriate position, the screw is turned... Rod 506 is fixed to connecting rod 503 by abutment. Heat dissipation holes 507 and holes 502 dissipate heat. Auxiliary groove 509 increases the friction between the hand and the outer shell 508, preventing slippage when pulling the outer shell 508. Slide rod 504 limits the slip ring 505, preventing it from shifting during use and improving the stability of the slip ring 505. Protective pad protects connecting ring 501, preventing excessive wear during use. Stainless steel increases the service life of connecting ring 501, preventing deformation during use. Moreover, stainless steel has a high melting point and is not affected by motor heat. Aluminum rod has strong thermal conductivity, which increases the heat dissipation efficiency of hole 502.
