Abstract

The significant advantages of permanent magnet synchronous motors, such as very good dynamic properties, high efficiency and power density, have led to their frequent use in many drive systems today. However, like other types of electric motors, they are exposed to various types of faults, including stator winding faults. Stator winding faults are mainly inter-turn short circuits and are among the most common faults in electric motors. In this paper, the possibility of using the spectral analysis of symmetrical current components to extract fault symptoms and the machine-learning-based K-Nearest Neighbors (KNN) algorithm for the detection and classification of the PMSM stator winding fault is presented. The impact of the key parameters of this classifier on the effectiveness of stator winding fault detection and classification is presented and discussed in detail, which has not been researched in the literature so far. The proposed solution was verified experimentally using a 2.5 kW PMSM, the construction of which was specially prepared for carrying out controlled inter-turn short circuits.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In stator winding fault, the amplitude of the fs component in the current negative sequence component increases significantly, while the positive sequence component is not sensitive.

    “The authors have proven that in the case of the stator winding fault, the amplitude of the fs component in the current negative sequence component increases significantly, while the positive sequence component is not sensitive to this type of failure.”

    From Fault Diagnosis and Fault-Tolerant Control of PMSM Drives–State of the Art and Future Challenges (2022) · cites this paper as [48]

    Section 3 reports that the fs amplitude increases after an inter-turn short circuit and that the increase is greater in the negative-sequence component. It also reports an increase in the positive-sequence component and uses its amplitude as a fault-classifier feature, so the claim that the positive sequence is not sensitive is unsupported.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
