Step linear electrostatic motor

摘要

A linear electrostatic motor comprises a planar stator having a capacitive structure formed by a metal layer and a layer of dielectric material and a movable member having first and second groups of feet formed by a conductive thin film and arranged in rolling contact on the layer of dielectric material of the stator. In operation, the voltage pulses applied to the feet of one of the two groups have a shift, for example substantially of one half of a period, with respect to the voltage pulses applied to the other group of feet.
