Jae-Do Park received his Ph.D. degree from the Pennsylvania State University, University Park, in 2007. Park is currently an Assistant Professor of electrical engineering at the University of Colorado, Denver. He is interested in various energy and power system research and education areas, including electric machines and drives, energy storage and harvesting systems, renewable energy sources, and grid-interactive distributed generation systems. Prior to his arrival at the University of Colorado, Denver, Park worked for Pentadyne Power Corporation in California as Manager of Software and Controls, where he took charge of control algorithm design and software development for the high-speed flywheel energy storage system. He also worked at the R&D Center of LG Industrial Systems, Korea, where he developed induction machine drive systems as a Research Engineer.

Design and Implementation of a Fundamental Electric Machine Laboratory using Industrial Devices ABSTRACT The design and implementation of the instructional electric machine laboratory is describedin this paper. The objectives of this project are to upgrade 50-year old laboratory equipment andto provide students with hands-on experience on up-to-date electric machines, drives and instru-ments, as well as to improve their understanding of the theory learned from lectures. Instead ofthe systems especially designed for educational purpose, off-the-shelf industrial devices have beenselected for the experiments to make them more realistic and thus closer to a work situation, aswell as more cost effective. Experiments, hardware components, instruments and student feedbackabout the laboratory course offered are presented. The electric machine laboratory is a fundamental course for all electrical engineering studentsand it has been offered in electrical engineering programs in many institutions. Although powerengineering education has been declining for the last decade, its importance has recently been rec-ognized and many laboratory and course improvements for power engineering education are beingsuggested. However, many of them have focused on new technologies, such as software-basedvirtual laboratories, web-based remote laboratories, and the implementation of new courses formachine drives or power electronics. Even though they are all valid in terms of reflecting contem-porary technologies and industry needs, attention to the introductory electric machine laboratoryis required as well, because it often has obsolete, out-of-date equipment that gives a negative im-pression about power engineering to students. While electric machines have not changed much in their structures and materials, drive tech-nologies for machines and instruments have made tremendous advances, which is why many sug-gestions for improvement have focused on that part. However, given the fact that the machines,drives and instruments can be shared with the electric drives laboratory, the introductory electricmachine laboratory can be renovated at the same time as the drives laboratory. It is a legitimateopportunity to revamp the experiments for the introductory machine laboratory using up-to-datetechnologies and it will improve the cost-effectiveness.
