Development of an experimental device for torsional vibration control using PMSM

Abstract

Permanent magnet synchronous motors are widely used in industrial rotating machinery such as automobiles. In this study, a torsional vibration test equipment with PMSM and two inertias was developed for basic research on torsional vibration control using a permanent magnet synchronous motor. To obtain the desired natural frequency, a plate spring is designed as torsion springs. We also obtain the frequency response from the experiment and estimate the stiffness and damping coefficient of the test equipment.
