Three dimensional magnetic field computation by a coupled vector-scalar potential method in brushless DC motors with skewed permanent magnet mounts - the formulation and FE grids
(
IEEE
, 1994 , Article)
A three dimensional finite element (3D-FE) method for the computation of global distributions of 3D magnetic fields in electric machines containing permanent magnets is presented. The formulation of this 3D-FE method ...
Coupled vector-scalar potential method for 3D magnetostatic field computations using hexahedral finite elements
(
IEEE
, 1996 , Article)
This paper introduces a three dimensional finite element (3D-FE) method based on a coupled vector-scalar potential formulation. The method is most suited for large-scale magnetostatic field applications containing mixed ...

This paper reviews recent advances in the state of the art of applying three-dimensional finite-element (3-D-FE) magnetic field computation techniques to the analysis and quantification of parameters and performance of ...
Optimization of the skew angle of rotor poles in permanent magnet machines based on the inverse problem method
(
IEEE
, 1999 , Article)
This paper presents optimization of the skew angle of rotor magnetic poles in permanent magnet brushless dc machines. The skew angle optimization is achieved using the gradient based inverse problem methodology. The paper ...
Constituents of plants growing in Qatar XX. Phytochemical investigation of anastatica hierochuntica: NOTE
(
Taylor & Francis
, 1993 , Article)
A study of the lipid fraction of Anastatica hierochuntica (Cruciferae) resulted in the isolation of hydrocarbon (mainly C25H52, C29H60 AND C31H64) AND sterol fractions (P-sitosterol, campesterol, stigmasterol AND cholesterol). ...
