Abstract The research of temperature field is critical to the stable operation of underwater motor. Taking into account the influence of rotating magnetic field and harmonic magnetic field, the distribution law of iron loss density in different regions of the stator was analyzed. The distribution of copper loss and oil friction loss was analyzed, through considering the relationships among the winding and guide bar resistance, lubricating oil viscosity and motor temperature. Then a novel method was proposed to conduct a coupling analysis on the temperature field of underwater motor. The method considers two loading conditions in terms of spatial distribution of iron loss and time-varying loading of oil friction loss and copper loss. Comparing with the results of uniformly distributed losses, the motor temperature is significantly reduced by using the new method, and the maximum temperature is decreased by 70.4%. Besides, the influential order of factors was identified through orthogonal test. The rationality of this loss loading method for the research of underwater motor temperature field is verified by water tank experiment.

Key words： Underwater motor loss loading method temperature field experiment research
