[L-HT-217] Modeling Forced Air Cooling
Temperature rise in each part has become a major issue due to higher motor output density. If designers only focus on the magnetic design, the motor design will not satisfy the thermal design requirements, which could entail significant rework. That is why taking into account for the cooling system and rest of the thermal design is essential during the magnetic design stage.
Industrial motors often employ a self-ventilation system that circulates air using a fan mounted to the motor shaft. JMAG can reproduce the forced air cooling through ducts and other parts to predict the temperature changes in each part.
This case study simulates a forced air cooling system inside an induction machine using two different types of fans. The results illustrated how different airflow rates of the fans affect the saturation temperatures in each part.
