해석적 방법에 의한 영구자석 동기전동기의 영구자석 와전류 손실 해석

This paper deals with the inductance deduction of axial flux permanent magnet wind power generator based on electromagnetic field theory. On the basis of magnetic vector potential and polar-coordinate system, the magnetic field solutions due to stator winding current are obtained. In particular, the 3-D problem is solved by introducing a special function for the radial position. Besides, the analytical modeling of ring-wound winding which is has radially nonhomogeneous width in polar coordinate system is proposed.
