A Coupled Vector-scalar Potential Method For Permanent Magnet Modeling in Large-scale 3d-Fe Magnetic Field Computations
Abstract
This paper introduces a magnetic scalar potential (MSP) formulation of permanent magnet (PM) modeling. This formulation is suited for use in coupled (combined) vector-scalar magnetic potential (CMVP-MSP) 3D-FE algorithms and computation of large-scale magnetic field problems in elecltric machinery and devices [ 1,2]. This formulation and method facilitate substantially the handling of PM materials, current-carrying conductors, and nonlincar anisotropic laminated iron cores, as adjacent subregions within one global solution region (volume) of a given device.
