Distinguished IEEE/IAS Lecturer Dr. Mircea Popescu is presenting a lecture on “Hybrid and Electric Vehicles in Europe: Challenges and Practical Solutions for the Electric Machine Drive Systems,” from noon-1:30 pm on Thursday, June 19, 2014 in the Robert W. Galvin Center for Electricity Innovation located in the IIT Tower, 16th Floor in the West Classroom. This is a free event. Lunch will be provided.

The lecture will cover some of the latest developments in European HEV industry and include state of the art topologies and emerging trends. Other topics will include heating and ventilation, manufacturing technologies like segmented stators for brushless PM machines and die-cast copper rotors for induction motors, and the role of computer aided engineering in the industrial environment. Particular emphasis will be placed on the possible shortage of NdFeB magnets and on potential alternatives for rare-earth free or magnet free solutions. Various cooling systems for electric machines will be illustrated in detail, with a focus on forced convection – air or liquid – methods. Topics such as the risk for PM demagnetization, the effect of switching frequency, supplementary AC losses and magnet losses will also be discussed. A comparison between the permanent magnet motor solutions – interior and surface rotor mounted motors – with rare-earth magnet-less solutions – induction motors and reluctance motors will also be presented.
