Ep. Furlani et Ma. Knewtson, A 3-DIMENSIONAL FIELD SOLUTION FOR PERMANENT-MAGNET AXIAL-FIELD MOTORS, IEEE transactions on magnetics, 33(3), 1997, pp. 2322-2325
A formula is presented for computing the field in axial-field permanen
t-magnet motors, The formula is based on ii three-dimensional (3-D) an
alytical analysis and is expressed in terms of a finite sum of element
ary functions, It is readily programmed and ideal for parametric studi
es of field strength. It is also well suited for parallel processing a
nd could be developed into a motor model for real-time performance sim
ulations, It is applied here to a practical motor geometry and verifie
d by the use of 3-D finite element analysis (FEA).
