Back Emf And Torque Characteristic Of N-n And N-s Type Of Multi-disc Axial Flux Permanent Magnet Synchronous Generator

摘要

The comparison of torque characteristic and back electromotive force (back-EMF) between the N-N and N-S type of multi-disc coreless axial flux permanent magnet synchronous generator (multi-disc coreless AFPMSG) is presented in this paper. All results were obtained by 3D numerical analysis using the software package Ansys Workbench v11. The calculation formulas of back-EMF and electromagnetic forces have been given as well.
