Using low-frequency electromagnetic-thermal CFD simulation to accelerate traction motors innovation

Optimizing the cooling of an EV/HEV traction motor

Traction motors, which are mainly permanent magnet, have higher power densities to lightweight the powertrain. While lightweighting reduces electromagnetic and thermal masses, these machines are prone to saturation and overheating at peak loads, especially at elevated temperatures. Therefore, important to ensure proper cooling for traction motors since their intermittent drive-cycle operation, service life, permanent magnet and insulation stability are temperature-rise dependent.

This webinar will introduce part of the Simcenter traction motor low-frequency electromagnetic-thermal CFD solution. The solution will show how to quickly set up the motor model, analyze its electromagnetic and thermal performance and electromagnetic heat-losses, and then run design optimization to improve cooling by accounting for the flow rates and the allowable pressure drop.

Design the appropriate traction motor cooling system for increased safety and reliability and maximized performance
