As one of the electromagnetic detecting approaches, the magnetic flux leakage (MFL) method has the best effect for the detection of broken wires. However, existing sensors based on MFL method still have some problems. (1) The size of the permanent magnet exciter is usually designed according to experience or rough calculation, and there is not enough depth analysis for its excitation performance; (2) Since the detectable angular range for a single Hall component is limited, Hall sensor arrays are often employed in the design of MFL sensors, which will increase the complexity of the subsequent signal processing due to the extensive use of Hall components; (3) Although the new magneto-resistance sensor has higher sensitivity, it is difficult to be applied in practice because of the requirement of the micron-level lift-off. To solve these problems, a sensor for the detection of broken wires of steel wire ropes based on the principle of magnetic concentration is developed. A circumferential multi-circuit permanent magnet exciter (CMPME) is employed to magnetize the wire rope to saturation. The traditional Hall sensor array is replaced by a magnetic concentrator to collect MFL. The structural parameters of the CMPME are optimized and the performance of the magnetic concentrator is analyzed by the finite element method. Finally, the effectiveness of the designed sensor is verified by wire breaking experiment. 1\u20135 external broken wires, handcrafted on the wire rope with a diameter of 24 mm, can be clearly identified, which shows great potential for the inspection of steel wire ropes.<\/jats:p>","DOI":"10.3390\/s19173763","type":"journal-article","created":{"date-parts":[[2019,8,30]],"date-time":"2019-08-30T10:31:17Z","timestamp":1567161077000},"page":"3763","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["A Sensor for Broken Wire Detection of Steel Wire Ropes Based on the Magnetic Concentrating Principle"],"prefix":"10.3390","volume":"19","author":[{"given":"Yiqing","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Mechanical and Automotive Engineering, Qingdao University of Technology, Qingdao 266520, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luyang","family":"Jing","sequence":"additional","affiliation":[{"name":"College of Mechanical and Automotive Engineering, Qingdao University of Technology, Qingdao 266520, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weixiao","family":"Xu","sequence":"additional","affiliation":[{"name":"College of Mechanical and Automotive Engineering, Qingdao University of Technology, Qingdao 266520, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weixia","family":"Zhan","sequence":"additional","affiliation":[{"name":"College of Mechanical and Automotive Engineering, Qingdao University of Technology, Qingdao 266520, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiwen","family":"Tan","sequence":"additional","affiliation":[{"name":"College of Mechanical and Automotive Engineering, Qingdao University of Technology, Qingdao 266520, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"109","DOI":"10.3390\/s18010109","article-title":"Magnetic Flux Leakage Sensing and Artificial Neural Network Pattern Recognition-Based Automated Damage Detection and Quantification for Wire Rope Non-Destructive Evaluation","volume":"18","author":"Kim","year":"2018","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"80","DOI":"10.1016\/j.ndteint.2015.06.006","article-title":"Use of gamma rays in the inspection of steel wire ropes in suspension bridges","volume":"75","author":"Peng","year":"2015","journal-title":"NDT E Int."},{"key":"ref_3","first-page":"155","article-title":"Electromagnetic testing, a reliable method for the inspection of wire ropes in service","volume":"22","author":"Weischedel","year":"1989","journal-title":"NDT Int."},{"key":"ref_4","doi-asserted-by":"crossref","unstructured":"Zhang, J., Zheng, P., and Tan, X.
