Abstract

Disk motors characterized by a flat structure and high power density are suitable for use in shaftless rim thrusters. This study proposes a novel stator coreless disk motor with skewed wave winding, which is intended for use in shaftless rim thrusters of small underwater robots. It analyzes the generation mechanism of back electromotive force (EMF) and electromagnetic force for the skewed wave winding and designs three disk motors with different pole numbers (12 poles, 16 poles, and 24 poles) by varying the winding skewed angle. A positive correlation between motor efficiency and the number of poles is demonstrated through a finite element simulation on disk motors with different pole numbers. Finally, a prototype of the 16-pole motor is fabricated and tested to validate the effectiveness of the previous motor design.

用于无轴轮缘推进器的带斜波绕组的新型定子无铁芯盘式电机

盘式电机具有扁平结构和高功率密度的特点，适合用于无轴轮缘推进器。本研究提出了一种带有斜波绕组的新型定子无铁芯盘式电机，可用于小型水下机器人的无轴轮缘推进器。研究分析了斜波绕组的反向电动势（EMF）和电磁力的产生机理，并通过改变绕组斜角设计了三种不同极数（12 极、16 极和 24 极）的盘式电机。通过对不同极数的盘式电机进行有限元模拟，证明了电机效率与极数之间的正相关关系。最后，制作并测试了 16 极电机的原型，以验证先前电机设计的有效性。
