Algorithmic Approach for Slot Filling Factors Determination in Electrical Machines
2018
In several industrial sectors, such as electric and hybrid traction, the demand for increasingly efficient and high power density electrical machines has grown considerably over the last few years. The improvement of slot filling factor of the electrical machines is an useful provision to satisfy this request. In particular, this topic has been the subject of interest for the industrial sector in recent years, since the technology of winding processes have evolved and allow an economically sustainable realization of windings with an ordered structure rather than randomly. The winding phase must be supported by an accurate design process in which it is possible to evaluate the maximum slot f…
Obtaining the electrical model of a power transformer by means of finite element software
2005
Abstract. The behaviour of transformers and inductors working at high-frequencies and high power density can dramatically differ from the ideal or low-frequency operation. Their performance is very dependent on the magnetic material, operating frequency and physical construction. In this paper, finite element analysis (FEA) is used to obtain an accurate characterization of the electromagnetic behaviour of these magnetic components.
<title>Family of devices for the study of laser eam behavior in particular conditions</title>
2002
Laser applications in science and technology are based on the special properties of laser radiation, such as monochromaticity, coherence, beam concentration and high power density. Since the laser was discovered, an ever increasing number of applications have been found for it in the most diversified fields. Despite this, its wide possibilities are still by no means fully known or exhausted. Further development is continually taking place in the design of new systems. The generation of the photons is in itself an optic-electronic process. The trajectory of the laser beam is linear. It could be modified by a lens or by a mirror. We built some devices, in order to know how a laser beam could …
Target Cooling Options for Neutron Sources at High Power Densities
2014
Abstract Compact neutron sources in many cases beat large ones when it comes to power density; thus, many issues concerning cooling are shared, and each party can learn a lot from the other facilities. Starting from accrued experience with water cooling at moderate power densities in SINQ over the last 15 years, a brief overview will be attempted showing the relevant parameters and specific approaches at several existing and planned neutron (spallation) sources. Extensions from the established ground of cooling with water will be sketched in two directions. An outline of an experiment planned for freshly determining in a representative geometry the hard limit for water cooling, i.e. full bo…
