Special Issue Information

Dear Colleagues,

Electric motors are undoubtedly the key module in drive systems covering a wide range of modern industrial applications such as electric vehicles, elevators, UAVs and ships. Their research development is particularly focused on optimal design and energy-saving potential by achieving the best possible performance. In these cases, the main role is played by power electronics, where with the evolution of semiconductor elements and new control techniques, motor driving is carried out with high precision, minimizing the possible losses of harmonic phenomena due to the inverter. In addition, it is worth noting that their continuous operation and their stress under extreme operating conditions poses a significant risk, disturbing the smooth operation compromising the production process. The current field of research concerns their continuous monitoring and the investigation of various techniques in order to minimize the possibility of unexpected consequences. In order to minimize maintenance costs and achieve optimal service, predictive maintenance is essential to accurately estimate the severity of a possible failure in the future. The integration of smart sensors, the internet of things, the use of machine learning and algorithms for data processing are key models for achieving operationally efficient and reliable systems.

We are pleased to invite you to participance in our Special Issue, which will focus on the latest developments and innovations in the field of electric motors. Your contribution of an article or review will be a valuable addition to our efforts to provide our readers with a Special Issue of high quality and scientific value.

This Special Issue aims to highlight research developments in key aspects such as (i) the optimal design of electric motors in industrial applications, (ii) energy savings and efficiency, (iii) power electronics, (iv) control of electric machines, (v) techniques for continuous monitoring of the operating state of electric motors, (vi) the collection and processing of large volumes of data in real and continuous time using IoT, (vii) smart sensor placement and (viii) fault diagnosis using artificial intelligent and genetic algorithms.

The electrification of ships and the use of electric propulsion systems are projects which have attracted increased research and industrial interest in recent years. Efforts are particularly focused on reducing pollutants for better environmental conditions and increasing efficiency. The main source of propulsion for such a ship’s shafts is related to the operation of electrical machines. In this case, several advantages are offered, related to both reduced fuel consumption and system functionality. Nowadays, two types of electric motors are used in propulsion applications: traditional induction motors (IMs) and permanent magnet synchronous motors (PMSMs). The evolution of magnetic materials and increased interest in high efficiency and power density have established PMSMs as the dominant technology in various industrial and maritime applications. This paper presents a comprehensive comparative analysis of PMSMs and both Squirrel-Cage and Wound-Rotor IMs for ship propulsion applications, focusing on design optimization. The study shows that PMSMs can be up to 3.11% more efficient than IMs. Additionally, the paper discusses critical operational and economic aspects of adopting PMSMs in large-scale ship propulsion systems, such as various load conditions, torque ripple, thermal behavior, material constraints, control complexity, and lifetime costs, contributing to decision making in the marine industry.
