Salient pole wound field synchronous motors find many industrial applications, thanks to their favorable characteristics: reactive power regulation, stiff mechanical characteristic, and overall outstanding efficiency. Nevertheless, their competitiven

Abstract Herein, a set of experimental procedures is presented for determining the main electrical distributed parameters of the field winding in salient pole synchronous machines. It applies to the electrical characterisation of iron‐core power in

The purpose of this paper is to carry out an alternative to the present transient models for field wound synchronous machines, which is able to take into account the nonlinearity of the magnetic materials as well as the cross-magnetization. After pre

This work investigates the establishment of steady-state eddy currents in solid and laminated salient poles and rotor rim of synchronous machines due to a periodic excitation voltage. It shows that the presence of eddy currents in the rotor magnetic

One tie-rod from Milan Cathedral (15th century) recently broke in a defective cross-section. In order to infer the causes of failure, a metallurgical characterisation was performed, the results of which are discussed here. First, a visual inspection

Fire behaviour of R/C structures can be strongly affected by spalling phenomenon, which may offset the positive inherent features of concrete exposed to high temperature. This makes the screening of concretes by testing a key point in the design phas
