    摘要: A stator is adjustably attached to the frame of a crossed-flexure pivot galvanometer. The stator acts on a permanent-magnetic rotor, having radially facing poles, causing the rotor to torsionally oscillate, which causes the rotor to be displaced from an axis of rotation along a line of displacement. The resonant frequency of the galvanometer is controlled by adjusting the centering of the stator along a line between the radially facing poles of the permanent-magnetic rotor. With this adjustment, as the stator is brought closer to the magnet along the line between the radially facing poles, the frequency-lowering effect is maximized. As the stator is move away from the magnet along the line of displacement, the frequency-lowering effect is minimized.
