Abstract
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.关键词
