“…In order to increase the efficiency level, improvements are being made for the electrical energy systems on board considering air quality, global warming concerns, and emission regulations in the maritime sector. For this purpose, [35] stated that maximum efficiency will be achieved by an improved interface in electrical systems, energy saving lamps and capacitors using for electric motors. [36] evaluated the applicability, advantages and disadvantages of the electric propulsion system in different types of vessels also compared mechanical and hybrid propulsion system.…”

Many improvements are performed in the maritime industry to ensure sustainability and energy efficiency. The use of hybrid propulsion systems (HPS) in marine vessels constitutes one of the developments in this field. In this study,both economic and environmental benefits are targeted. The study aims to reduce the high fuel consumption of the engine per unit power at low loads and minimization of emissions by sourcing them from main engine by HPS. Overcoming the limitations of Annex VI (Prevention of Air Pollution from Ships) of International Convention for the Prevention of Pollution from Ships (MARPOL) are desired and the research hopes for a beneficial result on Energy Efficiency Measures such as Energy Efficiency Operational Indicator (EEOI). A comprehensive study is accomplished on the hybrid propulsion system components and the keywords used in the literature review are revealed. Furthermore, the articles that have “efficiency”, “vessel”, “propulsion” and “marine” topics published in Web of Science (WOS) between 1975-2020 are examined and 44 studies are obtained. The studies that have been reached are analyzed and interests of them are collect under the 18 heading and the focal point of each study is highlighted in article. According to the results, the hybrid system provides low fuel consumption, minimizes emissions and costs, complies with the regulations of the International Maritime Organization, uses renewable energy sources, encourages the use of electric motors in addition to internal combustion engines, increases the efficiency of energy storage systems among other things. This article will be a significant resource for academicians, experts and companies on the Hybrid propulsion system in setting their focus. Keywords: Hybrid propulsion, Energy saving, Global warming.

“…Electric drive systems have been widely used in electric vehicles, aircrafts and ships because of high efficiency, high reliability and low emission and pollution [1][2][3][4][5][6]. In these fields, the motor works at complex drive cycle and the output speed and torque vary frequently, which reduces system efficiency.…”

Multiphase permanent magnet synchronous motors (PMSM) are widely utilized in high power and high reliability electric propulsion systems. In electric propulsion systems, the motor may work at a low efficiency area for a long time, which increases energy consumption and reduces cruise range. In order to improve motor efficiency, this paper proposes a multiphase motor structure. The stator winding of proposed motor consists of three independent windings that have different rated speed and torque. In this paper, winding match mode, operation characteristic and efficiency characteristic are analyzed, and a torque distribution strategy with optimal efficiency is given. The results show that in propeller load such as electric aircrafts and ships, the proposed motor can reduce motor total loss and temperature rise in a drive cycle, which improves system efficiency, reliability and fault tolerance performance.
