APPLICATION OVERVIEW
Pair GT-FEMAG’s electromagnetic losses with GT-SUITE’s state-of-the-art 1D-3D thermo-fluids simulation environment to predict continuous torque and validate cooling design with the accuracy you need without the runtime cost of 3D CFD conjugate heat transfer. Integrate this thermal model into system-level environments using 1D thermo-fluid networks or machine-learning metamodels, capturing transient temperature distribution across a full drive cycle.
APPLICATION OVERVIEW
Simulate rotor and stator structural performance with built-in 2D mechanical finite element analysis. Rotor analysis covers the rotor-to-shaft press-fit, static centrifugal force for maximum-speed prediction, and plastic strain. Stator analysis covers the stator-to-housing press-fit.
APPLICATION OVERVIEW
Predict NVH directly in GT-FEMAG with full 2D mechanical finite element simulation of stator, housing, lobe, and winding vibration driven by electromagnetic forces. Connect to GT-SUITE’s 3D mechanical solver to resolve 3D mode shapes, link to mounting points and gears, and capture detailed NVH behavior — including additional harmonics introduced by inverter PWM controls via GT-SUITE’s inverter models.
