Continuum Representation of Wound Coils via an Equivalent Foil Approach
نویسنده
چکیده
Continuum methods for representing skin and proximity effects in round-wire windings have been previously presented in the literature. Although the economy of these methods is well-established, the existing approaches require preliminary numerical field computations to determine the equivalent material properties of the wound region. The present work derives approximate but closed-form expressions for the equivalent conductivity and permeability of regions filled with hexagonally packed round wire, allowing proximity and skin effects to be included with ease in 2D AC field computations.

Thermal Analysis of Foil Wound Concentrated Coils for Use in Axial Flux Permanent Magnet Alternators
Axial flux permanent magnet (AFPM) generators for small-scale wind turbine applications have proven to be a useful design due to their reliability and ease of construction. Their stators have been realized using concentrate coils of enameled copper wires embedded in an epoxy-resin composite mixture. A static setting, opposed to a dynamic machine environment, is utilized to study the steady stat...
متن کاملApplication of FSW to Join Aluminium Foil Winding Coils for Electrical Transformers
The technically pure copper is being replaced by aluminium as conductive material in electrical transformers for power systems. This evolution brings new manufacturing challenges. One major difficulty is the limited weld ability and non-acceptable residual deformations of the aluminium, when welded by fusion arc welding processes. The Friction Stir Welding (FSW) was selected for evaluation cons...

In this paper, rstly, we obtain some inequalities which estimates complex polynomials on the circles.Then, we use these estimates and a Moebius transformation to obtain the dual of this estimates forthe lines in upper half-plane. Finally, for an increasing weight on the upper half-plane withcertain properties and holomorphic functions f on the upper half-plane we obtain an equivalentrepresenta...
متن کاملA contribution to approximate analytical evaluation of Fourier series via an Applied Analysis standpoint; an application in turbulence spectrum of eddies
In the present paper, we shall attempt to make a contribution to approximate analytical evaluation of the harmonic decomposition of an arbitrary continuous function. The basic assumption is that the class of functions that we investigate here, except the verification of Dirichlet's principles, is concurrently able to be expanded in Taylor's representation, over a particular interval of their do...
متن کاملImage Classification via Sparse Representation and Subspace Alignment
Image representation is a crucial problem in image processing where there exist many low-level representations of image, i.e., SIFT, HOG and so on. But there is a missing link across low-level and high-level semantic representations. In fact, traditional machine learning approaches, e.g., non-negative matrix factorization, sparse representation and principle component analysis are employed to d...
