摘　　要：深海推进用永磁无刷电机在低温、高压的海水中运行,并且电机内部充油,其热源和散热条件与普通工业电机不同。准确计算推进电机的温升对其高功率密度与轻量化设计具有指导意义。以"思源号"全海深自治遥控潜水器(ARV)主推进电机为例,基于计算流体力学和传热学理论搭建了包含导管螺旋桨、推进电机及内外流域的三维稳态流场-温度场仿真模型,研究了电机充油及驱动螺旋桨旋转对其温升的影响,并分析了电机主要部件的温度分布。最后,通过温升试验验证了仿真分析的有效性和准确性。The permanent magnet brushless motor for deep-sea propulsion operates in the low-temperature and high-pressure sea, and the motor is filled with oil. Its heat sources and heat dissipation conditions are different from ordinary industrial motors. Accurate calculation of temperature rise of the propulsion motor has guiding significance for its high power density and lightweight design. Taking the main propulsion motor used on “Siyuan” full-ocean-depth autonomous remotely-operated vehicle(ARV) as an example, a three-dimensional steady-state flow field-temperature field simulation model including the ducted propeller, propulsion motor, internal oil and external water is built based on computational fluid dynamics and heat transfer theories. The influence of oil filling and propeller rotation on the motor temperature rise is studied, and the temperature distribution of its main components is analyzed. Finally, the effectiveness and accuracy of the simulation analysis are verified by the temperature rise experiment.
