Influence of electromagnetic forces on characteristics of acceleration transducer

Abstract

The paper presents construction of linear acceleration transducer (LAT) that offers enhanced sensitivity and conversion transconductance due to supplementary use of short-circuited conducting ring in the named LAT. By mathematical modeling we obtained design formulae that allow of calculating conversion characteristic of LAT considering short-circuited turn. The paper covers special cases at problem solution and presents experimental verification of analytical studies with required accuracy. Design formulae obtained by mathematical modeling and given in the paper allow of analyzing the influence of all parameters of LAT both particularly and in their interrelation on conversion characteristic of LAT. Furthermore, obtained formulae allow of constructing LAT with the most possible sensitivity and conversion transconductance with optimum ratio of construction parameters. Expressions obtained during analytical studies received empirical confirmation by conducted experimental studies. Mathematical modeling results presented in the paper may find a use in studies of electromechanical devices equipped with short-circuited turn (inductive elements, electromagnetic launcher, winding fault detectors of electrical motors and transformers etc)
