High Fidelity E-Motor Dynamics and NVH Simulation

Properly considering the excitation of the e-motor is essential when analyzing the NVH of e-drives. Typically, electromagnetic forces on the stator and torque on the rotor are precalculated using electromagnetic tools. The high-fidelity NVH workflow in AVL EXCITE™ M allows the calculation of stator forces and rotor torque within the dynamic simulation model depending on the rotor radial offset and tilt, taking into account rotor skew, controller settings, and real currents generated by the inverter (PWM influence).
