Synthetic Method of Complex Characteristics Evaluation Exemplified by Linear Stepper Actuator Characteristic Comparison

Abstract

Characteristics of electric stepping micro-machines could be changed or shaped by using many methods other than simple re-design of their electromagnetic circuit. Many possibilities of characteristics forming give us idea of using special methods of steering. For planning, simulation and evaluation of new modified characteristics objective apparatus that allows comparing complex characteristic curves is a must. During development of new stepper actuators steering method such requirement occurred. Because of complexity of stepper characteristic curve, its incapability being analytically described and its irregularity - synthetic method was proposed and developed. This method is based at analyses of geometric parameters of an area under a characteristic curve. Because it does not use particular features of stepper motors characteristics, it can be used to comparisons of all characteristic types. Especially these ones, in which an area under a curve is important, what is happening i.e. when estimating absorption.
