ENGR 581A2 - Coupled Electromechanical Systems

  • 3 credits

Coupled electrical and mechanical systems and the analysis of energy transfer between these systems. Analysis of field energy and the relationship between electrical, mechanical and electromagnetic forces. Analysis and design of linear motors, servo-motors, DC and motors are presented. Other topics include inductively coupled charging circuits and vibrational modes that can arise between coupled electrical and mechanical systems. Graduate standing.

James Cale


Dr. James Cale leads a research group at the National Renewable Energy Laboratory (NREL), a U.S. Department of Energy national laboratory in Golden, CO. His research focuses on modeling, control and design optimization of renewable energy systems. His interests are in the areas of biologically-inspired design and optimization methods, computational and applied electromagnetics, control of finite-inertia power systems, and machine learning algorithms.

Prior to joining NREL he worked as Member of Technical Staff at Advanced Energy, performing high-fidelity modeling and algorithm development for PV inverters. Before that he worked at Orbital ATK as a senior R&D engineer leading the design of advanced magnetic sensing, data acquisition and real-time pattern recognition systems for defense applications. His post-doctoral research was in the area of time-domain magnetic FEA for full-wave analysis of high frequency (1010 Hz) magnetics.

James earned his doctorate in electrical engineering (with honors) from Purdue University, where he was funded by an NSF IGERT fellowship. He earned his BSEE from Missouri University of Science & Technology (summa cum laude). He is a member of Tau Beta Pi, Mensa International, and is a Senior Member of IEEE.
