Description

Technical Field

[0001] This utility model relates to the field of AC motor technology with strong comprehensive protection performance, and in particular to an AC motor with strong comprehensive protection performance. Background Technology

[0002] In modern industrial production, AC motors are indispensable core equipment for power conversion. Their operational stability and reliability directly affect the efficiency of the entire production line and the lifespan of the equipment. However, traditional AC motors have many insurmountable limitations in heat dissipation and protection. Conventional heat dissipation structures mainly rely on heat sinks on the motor casing or passive ventilation holes for heat dissipation. However, when the motor is under high load and operates continuously for extended periods, it generates a large amount of heat internally. This heat cannot be quickly and effectively dissipated using traditional heat dissipation methods. As a result, the temperature of core components such as the stator and rotor inside the motor continues to rise. Not only does it accelerate the aging process of insulation materials, it can also easily cause motor overload and even serious malfunctions such as motor burnout. Traditional open heat dissipation holes are easily invaded by dust and moisture in complex and ever-changing industrial environments. Dust accumulation at the heat dissipation holes will further hinder heat dissipation, greatly reducing heat dissipation efficiency. Moisture intrusion may damage the insulation performance of the motor, causing internal short circuits and thus significantly shortening the motor's service life. In addition, traditional AC motors lack an effective self-cleaning mechanism and require regular manual cleaning and maintenance. This not only increases the company's operation and maintenance costs but also inevitably increases equipment downtime, affecting production efficiency.

[0003] As per authorization announcement number CN220234377U, an AC motor relates to the field of AC motor technology. It includes a motor body, a connecting seat at the bottom of the motor body, a buffer seat at the bottom of the connecting seat, and a vibration damping component between the connecting seat and the buffer seat to dampen vibrations generated during motor operation. The motor body contains sound-absorbing cotton and multiple sound-insulating blocks, with the sound-absorbing cotton connected to the sound-insulating blocks, which are arranged sequentially. A cavity is provided within the motor body, and the sound-absorbing cotton and sound-insulating blocks are all disposed within the cavity. The vibration damping component includes a buffer spring, a damping cylinder, and two sliders. This AC motor, according to this invention, has a simple principle and multiple functions. It is not only convenient to use but also effectively reduces noise through a dual noise reduction structure. Furthermore, the AC motor can promptly dissipate internal heat, preventing excessive internal temperature from affecting operational performance.

[0004] The aforementioned AC motor, during the heat dissipation process of the equipment, cannot effectively solve the problem of dust accumulation at the heat dissipation holes, leading to the gradual accumulation of dust, which seriously hinders the smooth flow of heat dissipation channels, thereby affecting the overall heat dissipation effect, making it difficult to effectively control the equipment temperature, and ultimately potentially affecting the normal operation and service life of the equipment. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides an AC motor with strong comprehensive protection performance, which can accelerate the air circulation efficiency inside the mounting housing and clean the heat dissipation holes at the same time.

[0006] The technical solution adopted by this utility model is as follows: it includes a mounting housing, a rotor is provided inside the mounting housing, a stator is provided inside the mounting housing and located outside the rotor, a rotating shaft is provided at one end of the rotor, the rotating shaft is rotatably connected to the mounting housing, and a heat dissipation component is provided at the other end of the rotor.

[0007] Preferably, in order to facilitate heat dissipation, one end of the mounting housing is provided with heat dissipation holes arranged in an array.

[0008] Preferably, in order to accelerate the airflow inside the mounting housing, the heat dissipation assembly includes a rotating shaft, which is fixedly connected to the other end of the rotor, and the rotating shaft is provided with heat dissipation fan blades.

[0009] Preferably, in order to facilitate cleaning of the heat dissipation holes, a mounting plate is provided at the other end of the rotating shaft, and a cleaning brush is provided on the mounting plate, which contacts the heat dissipation holes.

[0010] Preferably, in order to facilitate heat dissipation, the mounting housing is provided with heat sinks arranged in an array.

[0011] Preferably, in order to facilitate the installation of this AC motor, the lower end of the mounting housing is provided with a mounting bracket, and the mounting bracket is provided with mounting holes.

[0012] Preferably, in order to reduce the noise generated during the operation of this AC motor, the inner wall of the mounting housing is provided with sound insulation cotton, and the mounting housing is made of high-strength aluminum alloy.

[0013] Preferably, in order to effectively reduce the vibration transmission during the operation of this AC motor, the bottom of the mounting bracket is provided with shock-absorbing rubber, and the bottom of the shock-absorbing rubber pad is provided with anti-slip textures arranged in an array.

[0014] The beneficial effects of this utility model are:

[0015] The continuous rotation of the cooling fan blades through the heat dissipation components and rotor effectively promotes the flow of surrounding air, thereby significantly enhancing the overall heat dissipation efficiency. The mounting plate and the cleaning brush connected to it also rotate synchronously, realizing real-time cleaning of dust inside the heat dissipation holes. This effectively avoids the accumulation and blockage of dust, ensuring that the heat dissipation holes are always unobstructed. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] like Figures 1-5 As shown, this embodiment provides an AC motor with strong comprehensive protection performance, including a mounting housing 1, a rotor 2 inside the mounting housing 1, a stator 3 inside the mounting housing 1 and located outside the rotor 2, a rotating shaft 4 at one end of the rotor 2, the rotating shaft 4 being rotatably connected to the mounting housing 1, and a heat dissipation assembly 5 at the other end of the rotor 2. When the power is turned on, the stator 3 generates a rotating magnetic field, driving the rotor 2 to rotate at high speed. The rotating shaft 4 outputs power to drive external equipment. At the same time, the rotor 2 drives the heat dissipation assembly 5, which accelerates the air circulation inside the mounting housing 1 and dissipates heat from the inside of the mounting housing 1, thereby avoiding affecting the operation of this AC motor.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 5As shown, one end of the mounting housing 1 has an array of heat dissipation holes 6. The heat dissipation assembly 5 includes a rotating shaft 501, which is fixedly connected to the other end of the rotor 2. The rotating shaft 501 is equipped with heat dissipation fan blades 502, and the other end of the rotating shaft 501 is equipped with a mounting plate 503. The mounting plate 503 is equipped with a cleaning brush 504, which contacts the heat dissipation holes 6. The rotating shaft 501 rotates synchronously with the rotor 2, and the heat dissipation fan blades 502 on it agitate the air, accelerating the dissipation of heat from inside the motor through the array of heat dissipation holes 6 and the surface heat sink 7 at one end of the mounting housing 1. The high-strength aluminum alloy material further improves the heat dissipation efficiency due to its good thermal conductivity. The cleaning brush 504 on the mounting plate 503 at the end of the rotating shaft 501 continuously scrapes against the heat dissipation holes 6, removing the attached dust and impurities. The airflow generated by 2 carries away the dust and discharges it outside the mounting housing 1, ensuring unobstructed heat dissipation channels and preventing dust accumulation at the heat dissipation holes 6, which would severely hinder the heat dissipation channels and affect the overall heat dissipation effect. The mounting housing 1 is equipped with heat sinks 7 arranged in an array. The mounting housing 1 has a mounting bracket 8 at the bottom, with mounting holes 9 on the mounting bracket 8. The inner wall of the mounting housing 1 is equipped with sound insulation cotton 10, which absorbs and blocks the noise generated by the motor operation, reducing noise pollution. The mounting housing 1 is made of high-strength aluminum alloy. The bottom of the mounting bracket 8 is equipped with shock-absorbing rubber 11. The bottom of the shock-absorbing rubber 11 has anti-slip textures arranged in an array. The shock-absorbing rubber 11 buffers motor vibration by its own elastic deformation, and the anti-slip textures on the surface firmly grip the mounting surface to prevent the motor from shifting during operation.

[0025] In use, the motor is fixed to the designated mounting surface of the equipment through the mounting holes 9 at the bottom of the mounting bracket 8. The shock-absorbing rubber 11 at the bottom of the mounting bracket 8 will undergo slight elastic deformation under pressure, tightly fitting the mounting surface. The array of anti-slip textures on its surface further enhances the friction with the mounting surface, effectively preventing the motor from shifting due to vibration during subsequent operation. When the power is turned on, the stator 3 generates a rotating magnetic field, driving the rotor 2 to rotate at high speed. The rotating shaft 4 outputs power to drive external equipment. At the same time, the rotor 2 drives the rotating shaft 501 of the heat dissipation component 5 to rotate synchronously, and the cooling fan blades 502 on it agitate... The airflow accelerates the dissipation of internal heat from the motor through the heat dissipation holes 6 and surface heat sinks 7 arranged in an array at one end of the mounting housing 1. The high-strength aluminum alloy material, with its excellent thermal conductivity, further enhances the heat dissipation efficiency. The cleaning brush 504 on the mounting plate 503 at the end of the rotating shaft 501 continuously scrapes against the heat dissipation holes 6, removing the attached dust and impurities. The airflow generated by the cooling fan blades 502 then carries these dust particles out of the mounting housing 1, ensuring that the heat dissipation channel is unobstructed. During operation, the sound insulation cotton 10 on the inner wall of the mounting housing 1 absorbs and blocks the noise generated by the motor operation, reducing noise pollution.
