A new measurement system able to detect the occurrence of arcing between the pantograph and the overhead contact line was studied and set up. The system uses photomultiplier tubes to measure the duration of the ultraviolet emission due to electric ar

A direct self control (DSC) strategy is applied to an induction motor with two three-phase stator winding sets. A remarkable reduction in the electromagnetic torque harmonics, as well as a meaningful minimization of the machine current distortion, ar

PurposeThe purpose of this paper is to investigate the use of hybrid‐excitation solutions, using contemporaneously permanent magnets and field coils, for DC machines intended to operate as the core of high‐reliability drives in critical applicati

Permanent magnets synchronous machines are nowadays widely employed. In case of symmetrical construction, aligned mounting of the rotor and balanced supply, the distributed surface magnetic actions on the rotor feature a null resultant. Anyway, in ca

Electric and hybrid vehicles represent the future of ground transportation. In such vehicles, electric motor/s provide the propulsion thrust — eventually aiding the engine in case of parallel and mixed powertrains. On the other hand, x-by-wire tech

Utilities often provide power supply via standard 1-phase low-voltage AC feeders, at least in the range up to several kVA. In rural areas and developing countries, even MV 1-phase distribution grids are sometimes used. Nevertheless, 3-phase load appl

In some niche applications, e.g. emergency pumps operating in case of fire, a high reliability and a constant speed operation capability are basically required. This paper deals with the use of hybrid excitation in DC motors to permit a highly reliab

This paper shows a new sensor based on infrared images for monitoring pantograph catenary interaction. Due to the displacement of the contact point with respect to the reference position an image processing analysis of each frame is performed by usin
