Researchers have taken a prodigious consideration in characterizing and synthesizing zinc
substituted cobalt ferrite nanoparticles because of their substantial applications across …

Electrical steels can be classified into two groups: grain-oriented (GO) and non-oriented
(NGO) electrical steel. NGO electrical steels are mainly considered as core materials for …

The trend toward high power density, high operating frequency, and low profile in power
converters has exposed a number of limitations in the use of conventional wire-wound …

The two best-known methods for calculating high-frequency winding loss in round-wire
windings-the Dowell method and the Ferreira method-give significantly different results at …

The paper deals with analytical method of design and prediction of performance
characteristics for induction motors with solid steel rotor coated with copper layer. On the …

In this paper, the frequency-dependent resistance in Litz-wire planar windings for domestic
induction heating appliances is analyzed. For these inductors, in which the size is not an …

Previous methods for calculating power loss in litz-wire windings usually assume very fine
strands such that the diameter of strands is much smaller than skin depth. In this paper, we …

This paper investigates the profile of the copper losses in a 5.0-MW high-speed permanent-
magnet machine with form-wound winding. The machine was tested, and the test data were …

The more electric aircraft (MEA) has motivated aircraft manufacturers since few decades.
Indeed, their investigations lead to the increase of electric power in airplanes. The challenge …

Native application of finite-element method (FEM) to the analysis of skin and proximity
effects in multi-turn coils results in large equation systems, whose solution needs long …
