D-5 Study of Conversion Method of Simple Analysis Model for Rotary Stepper Micromotor

Abstract

A 3-phase electrostatic stepper micromotor was developed. To improve its performance for actual use, we have conducted numerical simulation to optimize the design. An improved simulation method is needed for calculation of various cases. To conduct circuit simulation of this micromotor, its structure is simplified, and a function for computing the force excited by the electrostatic field is added to the circuit simulator. We considered simplification method to achieve a reasonably accurate simulation.
