Abstract:
1. A mount damper for mounting a rotary drive source on a support body and absorbing vibration of the rotary drive source during driving rotation thereof, the mount damper comprising: a first electrode to be placed on a side of the rotary drive source; a second electrode to be placed on a side of the support body; a voltage control section for controlling voltage to be applied between the first and second electrodes to thereby change a distance between the first and second electrodes; an elastic body placed between the first and second electrodes, the elastic body having a hardness changeable with the change in the distance between the first and second electrodes; a storage section for storing vibration characteristics of the rotary drive source to be mounted; and a vibration sensor for measuring a degree of vibration of the rotary drive source during rotation thereof, wherein the voltage control section: selects a voltage causing no resonance based on a stored content in the storage section, and then applies the selected voltage between the first and second electrodes; obtains a measurement result of the vibration sensor by scanning the voltage applied between the first and second electrodes, and then corrects the stored content in the storage section based on the obtained result; and adjusts a value of the voltage to be applied between the first and second electrodes to thereby adjust the resonant frequency of the rotary drive source and the elastic body.
