How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: you progress at your own pace within each intake, so you can combine it with your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is FEMM, Ansys Maxwell, COMSOL Multiphysics AC/DC, MATLAB and Magnetics Inc. Inductor Designer, in free, academic or evaluation versions. Testing is studied through real procedures for BH curve tracing with controlled excitation, loss measurement on ferrite cores and Epstein frame testing of magnetic sheet. Assessment is continuous by module, plus the final project.
Standards covered: IEC 60404-2, IEC 60404-6, IEC 62044-3, IEC 60404-8-7, IEC 63300, IEC 60205, IEC 60401-3.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
