| Abstract | This paper introduces a magnetic scalar potential (MSP) formulation to model permanent magnet volumes. This formulation is suited for use in coupled vector-scalar magnetic potential (CMVP-MSP) 3D-FE computations of large-scale magnetic field problems in electric machinery and devices. Also, a new approach for direct calculation of armature winding flux linkages and associated induced emfs, from 3D-FE solutions, using stored energy and excitation function perturbation techniques, is introduced in this paper. A case-study permanent magnet brushless dc machine was used to demonstrate the utility of this method. |
