TITLE: "Wound Field Synchronous Machines for Electric Vehicle Traction"
ABSTRACT: Transportation industries are undergoing an electrification revolution. For land transportation, hybrid and fully electric vehicle (EV) propulsion powertrains are rapidly increasing in popularity. Significant investments are being made by automobile, motorcycle, and truck manufacturers and suppliers to reduce the cost and improve the performance of EV components. One of the most critical components of electric powertrains is the traction electric machine. Currently the most commercially popular EV traction machine topology is interior permanent magnet synchronous machines (IPMSMs) using rare earth Neodymium Iron Boron (NdFeB) permanent magnets (PMs). There are significant price volatility and supply chain concerns regarding NdFeB magnets. A number of industrial and Dept. of Energy programs have focused on the reduction or elimination of NdFeB PMs. One PM free electric machine topology recently receiving interest for EV traction are wound field synchronous machines (WFSMs). This seminar will give an overview of the traction wound field synchronous machines developed in my research group including their design, prototyping, control, and testing.
BIO: Ian P. Brown received the B.S. degree in engineering from Swarthmore College, Swarthmore, PA, in 1999, and the M.S. and Ph.D. degrees in electrical engineering from the University of Wisconsin, Madison, in 2003 and 2009, respectively. Since 2012, he has been with the Illinois Institute of Technology where he is currently an Associate Professor in the Electrical and Computer Engineering Department. Previously he was with the Corporate Technology Center, A. O. Smith Corporation, Milwaukee, WI. His main research interests are high-performance electrical drives and the design and manufacturing of electric machines.
