Analysis of parameter effects on thrust force and optimum driving frequency in an electrostatic induction dielectric sheet conveyor
In recent years, electrostatic induction has been introduced as a new approach for transporting dielectric sheets. Electrostatic Induction Sheet Conveyor (EISC) is a kind of electrostatic induction actuator which can directly handle dielectric sheet objects, such as papers and plastic films in asynchronous state. The capability of sheet handling demands more studies to recognize parameters influencing thrust force and optimum driving frequency of dielectric sheets in this actuator. In this paper, using the proposed model in previous work, the effect of parameters including geometric parameters of slider and stator, electrical properties of dielectric sheet and environmental conditions on thrust force and optimum driving frequency of the actuator were analytically investigated.
Modeling of an electrostatic induction actuator for dielectric sheet conveying
This paper analyzes sheet transportation using the principle of electrostatic induction motors. This sheet transportation method has the capability of positioning and feeding dielectric sheets in processes and can be an interesting alternative to the existing mechanical conveyor. Although electrostatic sheet transportation was previously proposed based on a unique actuation model, it had limitations in surface resistivity of transported sheets. To break this limitation this paper utilizes another actuation principle namely electrostatic induction for conveying dielectric sheets. This study paper proposes an analytical model for actuation, in which the optimum driving frequency is analytically predicted, showing good agreement with the measured data.
