A Coupled Vector-scale Potential Method for Permanent Magnetic Modeling in Large-scale 3D-FE Magnetic Field Computations
Institute of Electrical and Electronic Engineers (IEEE)
IEEE Transactions on Magnetics
A magnetic scalar potential (MSP) formulation to model permanent magnet volumes is introduced. This formulation is suited for use in coupled vector-scalar magnetic potential (CMVP-MSP) 3-D-FE computations of large-scale magnetic field problems in electric machinery and devices. A new approach for direct calculation of armature winding flux linkages and associated induced emfs, from 3-D-FE solutions, using stored energy and excitation function perturbation techniques, is introduced. A case-study permanent magnet brushless DC machine is used to demonstrate the utility of this method.
