Abstract:

Advances in power electronic and machine control techniques are making the inverter-fed drives an always more attractive solution. Because of the number of inverter legs is arbitrary, also the number of phases results as a further degree of freedom for the machine design. Therefore, the multiphase winding is often a possible solution. Due to the increasing demand for high performance and high power variable speed drives, the research on multiphase machines has experienced a significant growth in the last two decades. Indeed, one of the main advantages of the multiphase technology is the po

Abstract:

The miniaturization of components enhances the difficulties related to their production with conventional technologies. At the same time this miniaturization trend opens the possibility to employ new non-conventional technologies that, like micro-EDM, are able to fulfil the market requirements and the technological challenges associated with the realization of micro components. Micro-EDM is able to machine any conductive material regardless of the hardness and high strength of the workpiece material and, thanks to the contact-less nature of the process, it leaves no residual stresses in the

Abstract:

Electro Adhesive Devices (EADs) are innovative actuators deployable for many applications, such as robotic grippers, locomotion systems for climbing and crawling robots, haptic devices, and gadgets for space applications. The most relevant advantageous features of EADs are the low energy consumptions and the lightweight and compact embodiment. An EAD always includes an electrode couple and one or more dielectric layers, which host and insulate the electrodes. The working principle is based on the electrostatic attraction that takes place between the device and the object once the electrodes

Since the 1970s, plasma’s capability to increase gases sterilizing potential has been demonstrated.

Years of studies and development have shown how they can be useful to inactivate different bacteria, spores, fungi and yeasts. The high amount of variables influencing a plasma bring to big differences in the effects it can have on a biological payload.

Abstract:

The remarkable discovery of flash sintering came across during the early work of Cologna et al. and emerged as an attractive technique in the field of ceramic processing. In this technique the applied electric field initiates the “flash” event, while the densification is controlled by the current density set. Sintering occurs in less than 5 s at a threshold temperature for a given applied field. The objective of this thesis is to analyse the phenomena of flash sintering with different ceramic oxides; such as alumina-zirconia composite, hydroxyapatite and doped-alumina.

This research work concerns the application of additive manufacturing (AM) technologies in new electric mobility sectors. The unmatched freedom that AM offers can potentially change the way electric motors are designed and manufactured. The thesis investigates the possibility of creating optimized electric machines that exploit AM technologies, with potential in various industrial sectors, including automotive and aerospace. In particular, we will evaluate how the design of electric motors can be improved by producing the rotor core using Laser Powder Bed Fusion (LPBF) and how the resulting de

Abstract:

Electodynamic technologies represent a challenging task in the nanotechnology field for producing multistructured and multifunctional membranes, based on nanofibers and nanoparticles that have been shown to be a good candidate as photocatalytic membrane on VOCs degradation. Before going toward fabrication of multistructured membranes, it is necessary to optimize the process of fiber formation. At this regard Response Surface Methodology (RSM) represents a versatile tool for exploring the space of the process or independent variables, empirical statistical modeling to develop an appropriate app

Abstract:

Today, the contribution of the transportation sector on greenhouse gases is evident. The fast consumption of fossil fuels and its impact on the environment has given a strong impetus to the development of vehicles with better fuel economy. Hybrid electric vehicles fit into this context with different targets, starting from the reduction of emissions and fuel consumption, but also for performance and comfort enhancement. Vehicles exist with various missions; super sport cars usually aim to reach peak performance and to guarantee a great driving experience to the driver, but great attention mu

Abstract:

The sustainable exploitation of energy and reduction of pollutant emissions are main concerns in our society. Driven by more stringent international standards, automobile manufacturers are developing new technologies such as the Hybrid Electric Vehicles (HEVs). These innovative systems combine the main benefits of traditional Internal Combustion Engines (ICEs) with those of Battery Electric Vehicles (BEVs), while overcoming their main drawbacks. HEVs can offer significant improvements in the efficiency of the propulsion system, but they also lead to higher complexities in the design and in the

The present thesis is focused on wave energy, which is a particular kind of ocean energy, and is based on the activity carried out during the EU project SEA TITAN. The main scope of this work is the design of a power electronic section for an innovative wave energy extraction system based on a switched-reluctance machine. In the first chapter, the general features of marine wave energy harvesting are treated. The concept of Wave Energy Converter (WEC) is introduced as well as the mathematical description of the waves, their characterization and measurement, the WEC classification, the operati

Abstract:

Vibration damping finds its application in almost any system or structure subject to oscillatory excitations. Vehicles, or better, the intrinsic nature of the environments that surround and interact with them demand certain degree of adaptability of the vehicle subsystems to a wide range of working conditions. This requirement, together with the fast development of electronics and motion transducers, leads to the interesting possibility of designing and implementing adaptive damping devices. In a context where technological alternatives are numerous, the present dissertation explores the po
