|Application||Tesla® X90D (EV HEV NVH)|
|Supply condition||Run-up at max torque|
|Noise sources||Electromagnetic, mechanical, aerodynamic|
|See also||Nissan Leaf, Renault Zoe|
Noise is measured close to electric powertrain and at driver’s hear. A run-up is done with maximum torque up to 120 km/h in free field environment. Eco mode and AVAS options are not activated.
Sound file and spectrograms
Sound of Tesla® X90D electric powertrain during run-up at maximum torque
Note: these sound files are the property of EOMYS; for authorized use in presentations, website, publications or technical work, please contact us
This sound file illustrates electromagnetically-excited noise of the electric powertrain of Tesla X90D EV. High pitch, whining noise with increasing frequency is due to slotting effects. Higher frequency sound occurring around 10 kHz is due to PWM effects with asynchronous switching frequency.
For a more detailed analysis, EOMYS provides technical trainings dedicated to EV HEV NVH.
Application to MANATEE
MANATEE software can be used to quickly calculate EV HEV NVH due to electromagnetic forces both in early design and detailed design phase, including PWM and slotting effects.
