Vibration Analysis Of A Permanent Magnetsynchronous Motor With A Gearbox

Abstract

Presented paper describes experiment carried out on a permanent magnet synchronous motor with a gearbox. Such experiment was conducted to diagnose the motor condition through acceleration measurement. In the beginning, there are described order analysis and Vold-Kalman filter method used to analyze vibration signal during constant but also variable rotational speed. Paper contains also information about the measurement extended with instrumentation based on CompactDAQ platform. Multiple test scenarios were put forward including constant motor rotational speed and torque as well as speed or torque transitions. The results showed benefits of proposed methods and also leaded to a few recommendations for following, more targeted, measurement.
