Novel motor noise reduction shell

Abstract

The invention relates to the technical field of motor auxiliary equipment, in particular to a novel motor noise reduction shell, which comprises a main box body, a top plate, an air inlet box and an air exhaust box. The top plate is detachably arranged above the main box body, the air inlet box is arranged on the side wall of the main box body, and the air exhaust box is arranged above the top plate; the air inlet box and the air exhaust box are both communicated with the main box body, a motor is arranged in the main box body, noise reduction lining plates are laid on the inner wall of the main box body and the lower surface of the top plate, and a plurality of peak-shaped protrusions are densely distributed on the surfaces of the noise reduction lining plates. According to the novel motor noise reduction shell provided by the invention, an inner wall with a noise reduction structure and a damping device are arranged, so that the noise of the motor during operation is effectively reduced.

Description

Technical field [0001] The present invention relates to the technical field of motor assisting equipment, and more particularly to a new type of motor noise. Background technique [0002] Motors are the most commonly used drives in machines or institutions, playing a pivotal role in various institutions, and the motor industry is an important part of the machinery industry, and it is important in the national economy. In theory, there should be no sound when the motor is running, so any sound issued in the motor operation can be classified as the noise of the motor, including electromagnetic noise, mechanical noise, aerodynamic noise. [0003] The cause of motor noise is caused by unbalanced noise caused by the imbalance of the rotor, and the noise caused by the bearing caused by the bearing, for example, the casing, stator, rotor, rotor, etc. are more rough, and in the final assembly, these factors It may lead to superposition of mechanical noise factors, so that the motor noise...

AI Technical Summary

Problems solved by technology

[0003] The main causes of motor noise are the noise caused by the imbalance of the rotor, the noise caused by the bearing and the noise caused by mechanical processing factors. For example, the machining accuracy of the casing, stator, rotor, and shaft is relatively rough. It may lead to the superposition of mechanical noise factors, which will increase the noise of the motor. The current motor casing generally has a relatively simple structure, which cannot effectively reduce noise and affect the use.
