Abstract EN
This paper is concerned with accurate, early, and reliable fault diagnosis using an enhanced vibration measurement technique based on short-time Fourier transform.
The novelty of this work lies in detecting very low-phase imbalance-related faults.
The energy contained within specified frequency bands centred on the rotor frequency and power supply frequency, and their sideband zones were calculated.
The technique was firstly demonstrated by simulated signals and then verified by experimental measurements taken from two different-sized test rigs.
The first one comprised a 1.1 kW variable speed three-phase induction motor with varying output load (no load, 25%, 50%, 75%, and 100% load).
Two types of common faults were introduced: imbalance in one phase as the electrical fault and misalignment of load as the mechanical fault.
The second test rig had a 3 kW three-phase induction motor again with varying load, and here the two seeded faults were: phase imbalance and one broken rotor bar.
The measured energy levels in the test conditions were found to be affected by type of fault and fault severity.
It is concluded that the proposed method offers a potentially reliable and computationally inexpensive condition monitoring tool which can be implemented with real-time monitoring systems.
