IPC: G05D19/02
Filed: 1987-11-10
Abstract: PURPOSE:To change inherence oscillation frequency and to prevent the generation of resonance by changing stress to be applied to a substance for preventing the generation of oscillation when a resonance state is generated and oscillation is increased. CONSTITUTION:When a motor 1 is driven and a rotary shaft 2 is rotated, a sense part 3 measures the variable of the rotary shaft 2 obtained at the time of rotating around the original shape of the rotary shaft 2 obtained in a static state and sends the measured variable to a signal processing part 7. The signal processing part 7 sends a driving signal to a stress generating part 5 in accordance with the variable, the generating part 5 expands/compresses a piezoelectric element in accordance with the driving signal and force based on the expansion/compression of the piezoelectric element is transmitted to the rotary shaft 2 through an axis 4b. Since the inherent oscillation frequency of the rotary shaft 2 relates to stress to be applied to the rotary shaft 2, the inherent oscillation frequency of the rotary shaft 2 is also changed in accordance with the stress. Consequently, the generation of resonance can be prevented.
