<p><P>PROBLEM TO BE SOLVED: To minimize a core loss by performing electromagnetic field analysis taking the influence of anisotropy and elastic bending into consideration. <P>SOLUTION: This core loss optimizing system includes a database for storing an H-B curve and a database for storing a W-B curve using anisotropic parameters an angleθformed by a predetermined direction of a soft magnetic material and the direction of a magnetic flux density in a minute region, and an elastic bending curvature K; a magnetic flux density vector determination means for determining the angleθand the magnitude B of the magnetic flux density, on the basis of the Maxwell's equations in the minute region; a core loss computation means for computing core losses of the minute region; a core loss summation means for determining the sum of the core losses of the minute region; a form change means for reducing the elastic bending curvature K applied to the soft magnetic material and changing the form of the soft magnetic material for minimizing the sum of the core losses; and a core loss optimization determining means for determining whether the sum of core losses be minimum or not. The core loss optimization computation is performed by the form change means, the core loss computation means, the core loss summation means, and the core loss optimization determining means. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
