Abstract:	摘要： This paper presents a new multistructure fluxgate magnetic sensor composed of Metglas ® Fe-based amorphous HB1 material. The core thickness of the fabricated structure is 0.0254 mm × 30 pieces, and its width is 5 mm. The magnetic loss of the fluxgate core is simulated through finite element analysis. The fluxgate sensor is experimentally analyzed over a frequency range 0.5-3 kHz. The sensor performance exploits the advantages of the multistructure core-shaped magnetic material as well as the second-harmonic operation mechanism. Excellent flux responses are detected for the triangular core sensor, which has different operating frequencies for magnetostriction variation, harmonic response, total harmonic distortion, noise level, sensor vibration, and sensitivity. The influence of magnetostriction, magnetic loss, and permeability in multiangled cores for different frequencies is analyzed. Our multistructure fluxgate sensor is suitable for various applications including power transformer and inverter for interior magnetic core fault detection, owing to its thin-film configuration, high sensitivity, high resolution, and low magnetic loss. 其他題名： TMAG 出版者： New York, NY: IEEE 出版日期： 2013-07-01 出處： IEEE Transactions on Magnetics, 2013-07, Vol.49 (7), p.3862-3865 資源來源： IEEE Electronic Library (IEL) 版權： 2014 INIST-CNRS 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
