| Abstract: | The static characteristics of an axial-flux permanentmagnet( AFPM) machine with coreless stator were investigated.Two-dimensional analytical method for prediction of the no-load magnetic field in the AFPM machine with coreless stator was derived. Electromotive force( EMF) and axial attraction force were deduced from the analytical method. These values obtained from analytical method were compared with those from finite element method( FEM) and agree well. Finally,a prototype was built for experimental validation and back EMF was measured. The results confirmed the validity of the proposed analytical method. |
