In this course, we will follow the electromagnetic design of a case study motor:

  • Axial-flux surface-mounted permanent magnet motor (sinusoidally excited)

In this example, we will consider the stator-rotor structure (considering the concentrated windings) and do analytic and finite element analysis. Please let me know if you have any questions via the following link:
