Influence of inverter voltage harmonics on the torque ripple of surface permanent magnet synchronous motor

Authors: Qiu, Hongbo | Zhang, Yong | Yang, Cunxiang | Yi, Ran

Article Type: Research Article

Abstract: The application of surface permanent magnet synchronous motor (SPMSM) driven by inverter is becoming more and more extensive. However, the voltage harmonics generated by the inverter will have a severe impact on the motor torque ripple. In order to analyze its impact, a 1500 r/min 3 kW SPMSM is taken as an example. Firstly, the two-dimensional finite element model is established, and the accuracy of the model is verified by the experiment. Secondly, the torque ripple is calculated and analyzed. The influences of voltage harmonic amplitude and voltage harmonic initial phase angle on torque ripple are mainly studied, and the variation law … Show more

A new quantitative non-destructive testing approach of broken wires for steel wire rope

Authors: Li, Xi | Zhang, Juwei | Shi, Jingzhuo

Article Type: Research Article

Abstract: In order to solve the problems including poor signal denoising effect, low recognition rate, and poor real-time performance in wire rope magnetic flux leakage (MFL) testing, this paper proposes a new algorithm combining kernel extreme learning machine (KELM) with compressed sensing wavelet (CSW). Firstly, we consider a new mechanism and regularized orthogonal matching pursuit (ROMP) into CSW, and combine double-density wavelet transform (DD-DWT) to improve the result of wire rope signal noise reduction; Then, an effective normalization method is developed to improve the accuracy of classification. Finally, the detection accuracy and efficiency in wire rope quantitative identification are ameliorated through … Show more
