Development of an Experimental Setup to Study the Load-Carrying Capacity of a Single-Stage Magnetic Rotor Suspension

Abstract

An installation for studying the dynamics and carrying capacity of a single-stage magnetic rotor suspension has been created. The evaluation of the proposed installation with regard to its potential use was carried out. The possibility of creating a rotor suspension based on hybrid active magnetic bearings was investigated with the help of the setup. If hybrid active magnetic bearings are used, the magnetic rotor suspension will allow to replace the existing classical active magnetic bearings used in vacuum, cryogenic and pumping equipment, reducing the energy costs without changing the geometric parameters of the existing units' housings. Experimental research of characteristics of axial active electromagnet is conducted (minimum power required to keep the rotor in vertical position is obtained). A finite-element model of the axial active magnetic bearing is created. The calculation results of the model are compared with the experimental data and the inductive transducer is calibrated. Experimental installation of a single-step rotor magnetic suspension is designed and manufactured. An electrical circuit for controlling the experimental setup is assembled. The program for PID-controller is given and its principle of operation is described with respect to the specified installation
