The method of notching auxiliary slots between the magnetic poles in the rotor and unequal thickness magnetic poles is proposed to improve the performance of the motor. By analyzing the magnetic circuit characteristics of the novel SIPMSM, the notching auxiliary slots between the adjacent magnetic poles can affect the q-axis inductance, and the shape of magnetic pole effects the d-axis inductance of the motor. The combined action of the two factors not only weakens the cogging torque, but also improves the flux weakening capability of the motor. In this paper, the response surface methodology (RSM) is used to establish a mathematical model of the relationship between the structural parameters of the motor and the optimization objectives, and the optimal design of the motor is completed by solving the mathematical model. Experimental validation has been conducted to show the correctness and effectiveness of the proposed SIPMSM.<\/jats:p>","DOI":"10.3390\/sym12010179","type":"journal-article","created":{"date-parts":[[2020,1,21]],"date-time":"2020-01-21T03:04:43Z","timestamp":1579575883000},"page":"179","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["A Novel Surface Inset Permanent Magnet Synchronous Motor for Electric Vehicles"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8246-9061","authenticated-orcid":false,"given":"Baojun","family":"Qu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology, Tianjin 300130, China"},{"name":"School of Mechanical Engineering, Shandong University of Technology, Zibo 255049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingxin","family":"Yang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology, Tianjin 300130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongjian","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Reliability and Intelligence of Electrical Equipment, Hebei University of Technology, Tianjin 300130, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel Angel","family":"Sotelo","sequence":"additional","affiliation":[{"name":"Department of Computer Engineering, University of Alcal\u00e1, 28801 Alcal\u00e1 de Henares, Madrid, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shilun","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Transportation and Vehicle Engineering, Shandong University of Technology, Zibo 255049, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhixiong","family":"Li","sequence":"additional","affiliation":[{"name":"Suzhou Automotive Research Institute, Tsinghua University, Suzhou 215134 China"},{"name":"School of Mechanical, Materials, Mechatronic and Biomedical Engineering, University of Wollongong, Wollongong, NSW 2522, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"746","DOI":"10.1109\/JPROC.2006.892482","article-title":"Electrical Machines and Drives for Electric Hybrid and Fuel Cell Vehicles","volume":"95","author":"Zhu","year":"2007","journal-title":"IEEE Proc."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"23939","DOI":"10.1109\/ACCESS.2018.2792448","article-title":"Permeance Analysis and Calculation of the Double-Radial Rare-Earth Permanent Magnet Voltage-Stabilizing Generation Device","volume":"6","author":"Zhang","year":"2018","journal-title":"IEEE Access"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1780","DOI":"10.1109\/TMAG.2009.2012820","article-title":"Multiobjective Optimal Design for Interior Permanent Magnet Synchronous Motor","volume":"45","author":"Kim","year":"2009","journal-title":"IEEE Trans.
