Imitation Model of a High-Speed Induction Motor With Frequency Control

Abstract

Purpose. To develop the imitation model of the frequency converter controlled high-speed induction motor with a squirrel-cage rotor in order to determine reasons causes electric motor vibrations and noises in starting modes. Methodology. We have applied the mathematical simulation of electromagnetic field in transient mode and imported obtained field model as an independent object in frequency converter circuit. We have correlated the simulated result with the experimental data obtained by means of the PID regulator factors. Results. We have made the simulation model of the high-speed induction motor with a squirrel-cage rotor speed control in AnsysRMxprt, Ansys Maxwell and Ansys Simplorer, approximated to their physical prototype. We have made models modifications allows to provide high-performance computing (HPC) in dedicated server and computer cluster to reduce the simulation time. We have obtained motor characteristics in starting and rated modes. This allows to make recommendations on determination of high-speed electric motor optimal deign, having minimum indexes of vibrations and noises. Originality. For the first time, we have carried out the integrated research of induction motor using simultaneously simulation models both in Ansys Maxwell (2D field model) and in Ansys Simplorer (transient circuit model) with the control low realization for the motor soft start. For the first time the correlation between stator and rotor slots, allows to obtain minimal vibrations and noises, was defined. Practical value. We have tested manufactured high-speed motor based on the performed calculation. The experimental studies have confirmed the adequacy of the model, which allows designing such motors for new high-speed construction, and upgrade the existing ones.

“…At O. M. Beketov National University of Urban Economy in Kharkiv (Ukraine), which hosts a certified laboratory for electric drive and electric apparatus in collaboration with Schneider Electric, a research platform for investigation of electric drive system and electric transients was built [25][26][27]. This platform consists of power part (ATV320 and ATV930 frequency converters), controllers part (M241 series controller) and operator part that realize SCADA human-interface device (HMIST-U sensor panel, specialized software SoMachine, SoMove and Vijeo Designer by Schneider Electric).…”

Active vibration control of a rotor-bearing-actuator system using robust eigenvalue placement method

“…where c is the orthonormalized modal matrix. Substituting equation (6) into equation (5) and multiplying the resulting expression by c T , the reduced equation of the system can be written as follows…”

“…The rotor vibrations caused by unbalances, process forces and system instabilities affect the machining accuracy and machine reliability, so an increasing amount of research is focused on the effective vibration control method for rotary machine. [1][2][3][4][5] Considering the advantages such as wide application and high stability, the active control is more suitable for adjusting to a myriad of load conditions and machinery configurations compared with the passive control. 6 The dynamical model of rotor system is essential for active vibration control design.…”
