Description

Technical Field

[0001] This application belongs to the technical field of special motor equipment, and particularly relates to a water-cooled and noise-reducing motor. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. Since motors have a wide range of applications in various fields of the national economy, with the rapid development of the national economy and the power industry, motors will face broad development space. At present, water-cooled motors with better cooling effects have been introduced. Therefore, it is also necessary to reduce the noise of such water-cooled motors. With the adjustment and optimization of the product structure in small and medium-sized motors, special-purpose motors will become the focus of the development of the motor industry, and their market demand and development speed will lead in this industry.

[0003] In a special motor with good noise reduction effect disclosed in CN220964524U, it includes a base; a junction box is installed at the top of the base, a connecting block is installed at the top of the junction box, and a housing is installed at the top of the connecting block; a sound insulation structure is arranged on the outer side of the housing, a cover body is movably connected to one side of the housing, disassembly and assembly structures are installed at the top and bottom of the cover body, and a rotating shaft is installed inside the housing; a fan blade is installed on one side of the rotating shaft, a rotor is installed on the outer side of the rotating shaft, a telescopic structure is installed on one side of the rotating shaft, and the telescopic structure includes a first telescopic rod, a second telescopic rod, a threaded rod, a rotating block and a rotating shaft, and the second telescopic rod is installed on one side of the rotating shaft.

[0004] The current development trend of motors is towards miniaturization. If a sound insulation structure is sleeved on a traditional special motor as in the technical solution of the comparative document, the structure of this motor cannot tend to be miniaturized, and it is not conducive to the heat dissipation of the motor. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a water-cooled and noise-reducing motor with a sound insulation structure inside the motor housing to solve the problems that in the comparative document, setting a sound insulation structure outside the motor housing for noise reduction of the motor cannot achieve the miniaturization of the entire motor structure and the heat dissipation of the motor itself.

[0006] In order to achieve the above technical purpose, the following technical solution is now provided: A water-cooled and noise-reducing motor includes a rotating shaft and a rotor arranged on the rotating shaft; it also includes a housing, a stator arranged inside the housing, and the housing includes a front cover plate at the front end, a rear cover plate at the rear end, and a water-cooling housing arranged outside the stator; wherein, a first noise reduction plate is arranged on the inner side of the front cover plate, a second noise reduction plate is arranged on the inner side of the rear cover plate, and a water channel structure is arranged inside the water-cooling housing, and a number of sound-absorbing cotton rods are filled in the water channel structure.

[0007] A honeycomb panel is provided on the front and rear covers, and sound-absorbing cotton rods are provided inside the water-cooling housing. By providing a noise reduction mechanism inside the motor housing, the miniaturization of the motor is achieved, and the structural strength of the motor housing is ensured.

[0008] In an implementable manner, the first noise reduction plate and the second noise reduction plate are honeycomb panels.

[0009] In an implementable manner, the sound-absorbing cotton rods include diameters of 5 mm, 8 mm, and 10 mm.

[0010] In an implementable manner, rotor sealing pressure plates are provided on the shaft at the front and rear ends of the rotor respectively. The rotor sealing pressure plates can seal the rotor, prevent air flow from being generated when the rotor rotates, that is, prevent resistance from being generated on the rotor, and also eliminate the generation of noise.

[0011] In an implementable manner, the aperture of the honeycomb panel is 8 mm, and the thickness is 7 - 8 mm.

[0012] The utility model has the following beneficial effects compared with the prior art:

[0013] In this technical solution, by arranging the noise reduction structure inside the motor, the miniaturization of the noise reduction motor is achieved. A first noise reduction plate is provided on the inner side of the front cover, and a second noise reduction plate is provided on the inner side of the rear cover. By arranging the first and second noise reduction plates, the original rib structure is replaced, which not only ensures the original structural strength of the cover, but also suppresses the noise at the front and rear ends. Arranging sound-absorbing cotton rods with multiple diameter models in the water channel can ensure noise reduction, and also ensure the structural strength of the water-cooling housing and the stability of the internal coolant.

By randomly inserting the sound-absorbing cotton rods 72 of the above-mentioned multiple diameter models into the water channel structure 71 during installation, vibration energy can be effectively absorbed. And the lengths of these sound-absorbing cotton rods 72 are the same as the length of the water channel structure 71.
