LEADING ENGINEERING SIMULATION CONFERENCE
Electric motors generate heat during their operation as a result of both electrical and mechanical losses. This emitted heat is essential to be removed in order to ensure the proper operation of the motor. The dissipation of the heat is achieved in most cases through conductive cooling (housing of the motor). To increase the outer heat exchange surface between the housing and the cooling medium usually fins are placed on the housing. Apart from their power electric motors may differ in the housing geometry (i.e. dimension, number and size of the fins etc). Thus, each motor should be designed and computed separately to investigate its cooling process. However, this is a highly time consuming numerical method. Aim of the current work is to demonstrate a parametric 3D model that allows the acceleration of the overall CFD procedure.
