近日，ABB公布了一种新型电力推进概念“ABB Dynafin”，其灵感来源于鲸鱼尾巴的运动姿态。与传统的轴系推进相比，“ABB Dynafin”有望降低22%的推进能耗。新的推进系统由一台主电机驱动一个特殊的叶轮，以每分钟30-80转的速度旋转。叶轮和叶片的联合运动同时产生推进力和转向力，为船舶提供突破性的推进效率和操控精度。该新型推进装置的初始设计功率为每台1-4兆瓦，特别适用于包括车客渡轮、海上风电支援船和游艇等中小型船舶，为其提供出色的机动性和动力定位性能。ABB预计，“ABB Dynafin”首台原型机将于2025年问世。

ABB has unveiled a new electric propulsion concept called ABB Dynafin. Inspired by the dynamic motions of a whale’s tail, it promises to reduce propulsion energy consumption by up to 22% compared to a conventional shaftline. The new propulsion concept features a main electric motor that powers a large wheel rotating at a moderate 30-80 rounds per minute. The combined motion of the wheel and blades generates propulsion and steering forces simultaneously, enabling what ABB says is “ground-breaking operational efficiency and precision” for ships. Initially available in the power range of 1–4 MW per unit, the new propulsion concept is particularly effective for medium-sized and smaller vessels, including ferries for passengers and vehicles, offshore support vessels operating at wind farms, and yachts. In addition, notes ABB, Dynafin delivers superior maneuverability, and positioning performance. ABB estimates that the first prototype will be available in 2025.
