About the course

Designers who wish to go beyond plugging datasheet values into simulation programs are invited to take this course to review the performance of conductors, insulation, and magnetic materials in electric machinery. Discussion will emphasize the usefulness and limitations of tabulated properties along with the effect of materials processing on performance.

Aleta WilderAbout the Instructor

Aleta Wilder provides materials characterization of magnetic, dielectric, acoustic, and mechanical properties through Wilder Innovations, LLC and also conducts contract R&D for high power density electric machinery at The University of Texas.

Ms. Wilder has over 30 years of experience in process development and performance improvement based on materials science & engineering. She earned a PhD from Alfred University-SUNY, an MS from Pennsylvania State University, and a BS from The University of Florida.

All courses include take-home reference materials!
