Development of an Electromagnetic Suspension Measuring System

Abstract

The paper deals with the development and implementation of a measuring system, that is used to determine the position of the rotor shaft inside an electromagnetic bearing and is an integral part of the electromagnetic suspension control system. The implemented measuring system of the electromagnetic suspension is described in detail. The measuring system is based on inductive position sensors. The measuring system is based on the Efectoriod IG6087 inductive position sensors, the NI ELVIS II platform, the LabVIEW software development and execution environment, and is controlled by a virtual instrument (VI). This VI allows real-time tracking of the coordinates of the geometric center of the steel trunnion cross section, as well as visualizing its position inside the electromagnetic suspension.
