FIRST STEPS TOWARDS DESIGN, SIMULATION, MODELING AND FABRICATION OF ELECTROSTATIC MICROMOTORS

Following the principles proposed by workers at Berkeley University, w e have developed a version of the electrostatic micromotor based on th e sacrificial layer method combined with oxidation of the rotor. In or der to study the behaviour of this electrostatic micromotor, we have e laborated two softwares. The first, called EFCREL, is to simulate the static operation of the electrostatic micromotors and the second, call ed EFDYN, is to simulate their dynamic operation. Both are based on a finite-element code, called EFCAD, for electromagnetic field computati on. They help us with the design of the fabricated micromotor and the simulation of its dynamic working, respectively. The elaboration of th ese two softwares represents our first steps towards a fully integrate d CAD (computer aided design) system for micromotors.
