Abstract

Motivated by a deceptively simple expression for the power conversion by an electric machine, we will develop from first principles a deeper understanding of what ultimately limits electric machine performance and where targeted research can relieve these limitations. Using motivating examples from aviation and renewable energy, we will examine the issues of how to balance the competing structural, thermal, and field constraints on an electric machine while driving toward increased torque and power densities. Choices to be discussed include whether it is better to separate constraints or to simultaneously address constraints through co-design.

David Torrey is a Senior Principal Engineer in the Electrical Systems organization at GE Research. He is a fellow of IEEE and IET. His research interests are in the design and control of electric machines, particularly within the context of integrated energy conversion systems. His application experience ranges from machine design for subsea hydrocarbon pumping, electric submersible pumps, to the design of next-generation generators for offshore wind turbines, to the design of engine-embedded generators to support hybrid-electric aircraft. He holds several awarded and pending patents in the fields of electric machines, power electronics, and control related to applications in transportation, renewable energy, oil and gas, and micro-grids. He has authored over 40 journal papers, over 70 conference papers, 3 book chapters, and one textbook in these areas. He supervised 13 doctoral theses while on the faculty at Rensselaer Polytechnic Institute.
