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:
