Short Preview Below

The copper-rotor induction-motor made its debut in automotive electric traction in 1990 in GM's Impact EV. Since then, this motor architecture has covered millions of miles on other vehicle platforms which will soon include Toyota's RAV4-EV. With the industry's attention focused on cost-effective alternatives to permanent-magnet traction motors, the induction motor has returned to the spotlight. This talk will overview where the copper-rotor induction-motor is today, how the technology has evolved since the days of the GM Impact, the state-of-play in its mass-manufacturing processes and today's major supply-chain players.

The use of silane chemistries tailored to promote the adhesion of performance and appearance coatings to metal substrates are requiring new methodologies for measuring, approving, and implementing on commercial aircraft. Engineering performance, lean manufacturing, environmental and employee safety considerations are driving the commercial aerospace industry to replace long standing conversion coating materials and processes. Tailored silane chemistries such as Boegel are being considered for many of these applications. Silanes work by reacting with metal oxides providing a strong covalent bond, cross linking to form a tough barrier and have an organic functional group tailored to react with the specific resin system in the subsequent coating. Traditionally conversion coatings such as anodize and chromate conversion coating performance is validated based on meeting standalone requirements.

FutureSteelVehicle's (FSV) objective is to develop detailed design concepts for a radically different steel body structure for a compact Battery Electric Vehicle (BEV). It also will identify structure changes to accommodate larger Plug-In Hybrid (PHEV) and Fuel Cell (FCEV) vehicle variants. The presentation will demonstrate seven optimized structural sub-systems that contribute to the program's 35 percent mass reduction goals and meet its safety and life cycle emissions targets. It will explain the advanced design optimization process used and the resulting aggressive steel concepts. Presenter Jody R. Shaw, US Steel

There has recently been a great deal of hypothesizing and prognosticating about the security of supply of the rare earths for the non-Chinese OEM automotive industry. The pundits and industry analysts have warned of demand destruction by substitution driven by sustained high prices as well as due to supply interruptions. What has been overlooked for the most part is that the issue is not about all of the rare earths; it is just about some of them, the critical rare earths. And even in that category there are two separate issues: 1) Is there enough production of the light rare earth, neodymium, to sustain current demand and can its non-Chinese production grow to meet expected non-Chinese demand? and 2.) Is there even enough production of the heavy rare earths, dysprosium and terbium, to meet current Chinese demand and is it possible to produce dysprosium a.) Outside of China, and b.)

As the need to develop better and less expensive batteries for automotive applications continues, we will likely need to examine potential tradeoffs between enhanced performance and costs. In particular, the choice of cathode materials automatically involves changes in performance and material costs. We will examine some of the possible cathode materials for use in next-generation battery packs, and the financial implications regarding those materials. Presenter Jon Hykawy, Byron Captial Markets
