Description

technical field [0001] The invention belongs to the technical field of vibration reduction and noise reduction, and in particular relates to an air compressor device for reducing mechanical resonance. Background technique [0002] Mechanical resonance is caused by the difference in rigidity, that is to say, the responsivity of two objects is different. Any system composed of two objects has their resonance frequency. Once reached, it will resonate. This usually depends on the bandwidth of the controller. If the gain of the servo drive is increased enough to reach the resonant frequency, the machine will start to resonate. [0003] This is because inertia at high frequencies decreases as frequency decreases. At low frequencies, the motion response is basically error-free. So, the change of inertia from low frequency to high frequency causes instability problem. As we have seen, there are various transfer units between the motor and the load, and these transfer units measu...
