Objectives

This module of MANATEE software carries e-NVH calculation over full torque/speed plane in four quadrant operation, which is especially useful for EV HEV NVH traction applications.

Summary

The modules calls several MANATEE simulations based on input Id/Iq maps to characterize the e-motor NVH behaviour in torque/speed plane on four quadrants (traction / braking / reverse modes), including noise map plots and detailed post processings. It can be combined with ALG.LEA, ALG.LIA and ALG.EVS, ALG.ENS to speed up calculations (using semi analytic NVH models, full map can be obtained in less than one minute of calculation).
