Description

Technical Field

[0001] The utility model relates to the technical field of three-phase asynchronous motors, in particular to a three-phase asynchronous motor with a noise reduction function. Background Art

[0002] The three-phase asynchronous motor is a common AC motor, which is usually used in various industrial and commercial applications. It uses a three-phase AC power supply to drive the rotor to rotate. It will generate noise during use, so noise reduction operations are required. However, the existing three-phase asynchronous motors with noise reduction function still have certain defects during use, such as;

[0003] For example, a three-phase asynchronous motor with sound insulation and noise reduction with publication number CN213547278U absorbs and isolates the noise inside the motor by setting a sound-absorbing layer, a first sound insulation layer and a second sound insulation layer, thereby reducing the volume of noise generated between the various connecting components inside the motor during operation; and by setting a noise-reducing and sound-insulating pad, the possibility and volume of noise generated between the motor and other equipment during the operation of the motor are reduced.

[0004] However, the three-phase asynchronous motor with sound insulation and noise reduction still has the following disadvantages in actual use:

[0005] Noise reduction is achieved through the provision of sound insulation layers and sound insulation pads. However, in actual use, the noise level generated by the motor itself cannot be reduced, so the overall noise reduction effect may be limited. In addition, due to the damping effect of the sound insulation pad, the energy efficiency of the motor may be affected, resulting in increased energy consumption and thus increased operating costs.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original three-phase asynchronous motor with noise reduction function. Therefore, we proposed a three-phase asynchronous motor with noise reduction function which can solve the above problems well. Utility Model Content

[0007] The purpose of the utility model is to provide a three-phase asynchronous motor with a noise reduction function, so as to solve the problem proposed by the above-mentioned background technology that noise reduction is currently carried out in the market by setting a sound insulation layer and a sound insulation pad, but in actual use, the noise level generated by the motor itself cannot be reduced, so the overall noise reduction effect may be limited, and due to the damping effect of the sound insulation pad, the energy efficiency of the motor may be affected, resulting in increased energy consumption, thereby increasing the operating cost.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows: the three-phase asynchronous motor with noise reduction function reduces the problem of noise generated when the shaft rotates by lubricating oil, solves the problem of being unable to reduce the noise level generated by the motor itself, uses sound insulation components to reduce the spread of noise, and reduces the problem of increased operating costs caused by the influence when the motor rotates. The specific contents are as follows:
