Description
Technical Field

[0002] Due to the interaction of magnetic fields in the air gap of the motor, electromagnetic forces that change with time and space are generated, causing vibrations of the stator and rotor of the motor, and then radiating noise. The motor should be correctly installed and maintained: ensure that the installation foundation is firm and level, and regularly check the fastening condition of the anchor bolts; perform alignment adjustment on the connection between the motor and the load to ensure smooth transmission. In order to reduce the generation of vibration and noise, vibration damping pads, shock absorbers, etc. will be installed on the motor base to reduce the transmission of vibration. The vibration of the motor will cause the vibration damping pad to be continuously subjected to forces such as stretching, compression, and shearing. Under the long-term vibration, the molecular structure inside the damping material will gradually suffer fatigue damage, resulting in a decrease in the strength and elasticity of the material. When replacing the shock pad, when the installation space of the motor is narrow and it is impossible to replace the shock pad without removing the motor, due to the need for transmission connection of the motor shaft, it is not conducive to replacing the base shock pad, thus making it inconvenient to suppress the vibration and noise generated by the motor.
