The structure and the working principle of the novel platform are introduced. An accurate model of the novel structure was established to calculate the magnetic density distribution for obtaining the parameters and performance of the magnetic suspension platform. The analytical model\u2019s results were verified by the finite element method. The driving force model of the magnetic suspension platform was established based on the Lorentz force. Twelve laser displacement sensors were applied to perceive the posture and vibration acceleration of the platform. The hardware information and the measurement models were introduced and established based on the layout. Finally, the Lorentz force characteristics of the proposed platform were investigated and compared with the conventional magnetic platform by the finite element analysis. The results show that the average magnetic flux density is 0.54T, the horizontal current stiffness along the X-axis is 63.1N\/A, the current stiffness along the Y-axis is 61.6N\/A, and the average output torque is 7.2 N*cm of the novel platform, larger than those of the conventional ones.<\/jats:p>","DOI":"10.3390\/s22114067","type":"journal-article","created":{"date-parts":[[2022,5,31]],"date-time":"2022-05-31T02:30:06Z","timestamp":1653964206000},"page":"4067","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Design and Analysis of a 6-DOF Magnetic Suspension Platform with an Improved Permanent Magnetic Array"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3683-7510","authenticated-orcid":false,"given":"Shinan","family":"Cao","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, TianGong University, TianJin 300387, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pingjuan","family":"Niu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, TianGong University, TianJin 300387, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Bai","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, TianGong University, TianJin 300387, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Precision Electromagnetic Equipment and Advanced Measurement Technology, Beijing Institute of Petrochemical Technology, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiang","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Precision Electromagnetic Equipment and Advanced Measurement Technology, Beijing Institute of Petrochemical Technology, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sha","family":"Sheng","sequence":"additional","affiliation":[{"name":"Institute of Precision Electromagnetic Equipment and Advanced Measurement Technology, Beijing Institute of Petrochemical Technology, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Precision Electromagnetic Equipment and Advanced Measurement Technology, Beijing Institute of Petrochemical Technology, Beijing 102617, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1625","DOI":"10.1007\/s12541-012-0213-1","article-title":"A compliant parallel mechanism with flexure-based joint chains for two translations","volume":"13","author":"Choi","year":"2012","journal-title":"Int.
