摘　　要：为了解对水下航行器用高比功率、短时工作制浸水式无刷直流电机工作瞬态温升及终了时刻温度分布规律,利用motor-CAD软件建立了温度场模型,计算了电机额定工况下的铁耗、欧姆损耗和永磁体涡流损耗,对电机在2种不同浸水温度下的温度场进行了计算,对铜、铝绕组材料在不同电流密度下的瞬态温升进行对比分析。研究结果表明,该浸水电机在不同条件下瞬态温升符合水下航行器工作性能要求,为电机设计提供热力学计算依据。To understand the transient temperature rise and the temperature distribution at end time of an immersion-type brushless DC motor with high specific power and short working time for an undersea vehicle,a temperature field model was established by using the software motor-CAD.The iron loss,ohmic loss and the current loss of the permanent magnet eddy were calculated,the temperature field of the motor was calculated at two different immersion temperatures.A comparative analysis of the transient temperature rise between copper and aluminum winding materials with different current density was carried out.The results show that the transient temperature rise of the immersion-type motor under different conditions is in accordance with the performance requirement of the undersea vehicle.This study may provide the basis for thermodynamic calculation in motor design.
