The present paper describes the basic characteristics of a multilayer thin electrostatic actuator supported
by lubricating oil rather than precise ball bearings for a fine-motion stage. The purpose of the present
research is to realize an easy-to-maintain multilayer thin electrostatic actuator having a simple structure
for high-precision motion. Lubricating oil is used to support the mover, which is constructed of thin
electrodes, andto reduce the frictionbetweenthemover andstator layerswithouttheneedforprecise ball
bearings. Eachlayer ofthe actuatorhas only one simple electrode that comprises several beams.Inorder to
examine the characteristics ofthemultilayer thin electrostatic actuator, a two-layer electrostatic actuator
was designed and constructed. First, the effect of the viscosity of the lubricating oil on the displacement
and force characteristics were examined in order to clarify the suitable lubricating oil characteristics. In
the experiments, low-viscosity oil provided a faster response and a larger thrust force. Next, a suitable
driving signal for the electrostatic actuator supported by lubricating oil was investigated experimentally.
Based on the results, control systems for the electrostatic actuator using suitable driving signals were
designed in order to examine the effectiveness of the actuator. The positioning results indicate that the
positioning accuracy is better than 15 nm. |
