Objective

This MANATEE software e-NVH post processing draws the amplitude of peak to peak torque ripple in torque speed plane (four quadrant operation) for traction applications such as EV HEV NVH.

MANATEE software allows to carry vibroacoustic design optimization of electrical machines while fulfilling torque ripple requirement, altough torque ripple is not correlated to noise and vibrations in the general case.

Result

Example of Maxwell stress harmonic map in torque / speed plane for EV HEV NVH analysis
