Abstract

This  paper  presents  a  mathematical  model  and numerical simulation results for heat transfer analysis that takes place at the frame level of a rotating electric machines provided with  longitudinal  cooling  fins.  For  this  purpose  a  relatively complex  three-dimensional  model  is  used,  numerical  treatable with  affordable  hardware  and  software  resources.  The  frame-environment convective heat transfer process is considered. The frame is cooled by forced convection in two cases: the thermal radiation  heat  transfer  is  taken  into  account  and  without considering  it.  Numerical  simulation  results  reveal  the  heat transfer pathways from the frame to the environment, and allow assessment of important parameters in designing the machine's cooling.
