Electrothermal Simulations of High-Power Electric Machines for Reliable Electric Aircraft

The aerospace industry is exploring a switch from hydrocarbon fuels to alternative forms of propulsion, including hybrid or fully electric propulsion. Multiphysics simulations are critical in reducing development costs and increasing the reliability and safety of electric powertrains.

A detailed electromagnetic model of the motor provides electromechanical metrics such as torque and heat losses for use in a conjugate heat transfer CFD model, so engineers can run thermal management system simulations. With bidirectional coupling between the magnetic and CFD solvers, engineers can predict demagnetization, thereby influencing the reliability of electric motor designs for electric aircraft.
