摘要：
A new electrostatic micromotor structure is presented in this paper. The actuation principle is based on the wobbling effect due to the use of direct electrostatic forces. A theoretical evaluation of the principal characteristics of the motor is presented. The motor is designed to present a low rotation speed (some 10 rotations per minute) suitable for direct actuation without speed reduction. The microfabrication technology used to realize the motor is based on deep-etch UV lithography, a nickel electroformed rotor and a titanium sacrificial layer. The flow chart of the technological steps implemented is detailed. First experimental results and improvements of the motor are discussed.
