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.
Разработана имитационная модель высокоскоростного асинхронного двигателя с короткозамкнутым ротором при
скалярном частотном управлении в программном пакете AnsysMaxwell&Simplorer. При моделировании на кластере
высокопроизводительных расчетов выполнены параллельные вычисления полевой модели электродвигателя
(AnsysMaxwell 2D) и модели, построенной на основе теории цепей (Ansys Simplorer), что позволило создать
имитационные модели, приближенные к их физическим прототипам. Выполнен анализ пусковых характеристик,
оптимизированы параметры электродвигателя. Даны рекомендации по выбору числа пазов статора и ротора
высокоскоростного асинхронного двигателя, что позволило существенно уменьшить вибрации и шумы в режиме
пуска.
