A low-noise and dust-proof motor for electrical equipment

Abstract

The invention provides a low-noise and dust-proof motor for electrical equipment, which relates to the technical field of low-noise motors and includes a motor. The top of the backing plate is integrated and fixedly connected with a screw sleeve, and the two screw sleeves are respectively provided with fixed tightening components, and the part of the motor shell corresponding to the rotor is covered with a muffler rotor jacket; The rotating part of the rotor of the motor is sealed by the sound-absorbing rotor jacket, rotates through the two jackets at the lower end of the rotating shaft, and fixes the bolt cylinder through the upper shell, and uses bolts to fix the corresponding part of the tail, so as to achieve a fixed effect, and fill the oil-soaked sound-absorbing cotton in the sound-absorbing tank. Since the oil-soaked sound-absorbing cotton is heavy, the sound-absorbing cotton can be fixed by a number of sound-absorbing cotton fixing rods, and the sound-absorbing cotton can isolate the noise inside the jacket shell, so as to achieve Noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of low-noise motors, in particular to a low-noise and dust-proof motor for electrical equipment. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate driving torque as a power source for electrical appliances or various machines. The generator is represented by the letter G in the circuit. Its main function The function is to convert mechanical energy into electrical energy. [0003] Now when the motor is running, due to the high-speed rotation of the internal rotor, the motor will vibrate rapidly as a whole. If there is an installation gap when the motor is installed, the jitter will be introduced into the gap to form a cavity, and the jitter will make noise. , if you need to reduce th...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a low-noise and dust-proof motor for electrical equipment, which solves the problem of the rapid vibration of the motor as a whole due to the high-speed rotation of the internal rotor when the motor is in operation. If there is an installation gap when the motor is installed, the jitter will be introduced into the gap to form a cavity, and the jitter will make noise. If you need to reduce the working noise of the motor when it is running, first fundamentally solve the gap that appears during installation, and then according to The characteristics of the sound itself, if you want to isolate the noise, you need to reduce the path it passes out, and increase the path length required for sound transmission, so as to reduce the noise
