Abstract :
Three-dimensional A-φ analysis of a recently developed cylinder-type concentration apparatus is dealt with. The model used attains compactness in size and high efficiency in flux concentration by assembling a conducting plate just inside one or several excitation windings. A four-component direct finite-element calculation method is applied, and three-dimensional distributions of the flux density, eddy current, and scalar potential are obtained. The divided direct calculation method is compared with an iterative method previously used by the authors
