Vibracoustic Stator Isolator reduces torque ripple produced by e-motors

To improve the noise, vibration and harshness (NVH) levels of e-mobility platforms and powertrains, Vibracoustic has developed a solution to reduce the torque ripple caused by the fluctuating magnetic fields of e-motors in battery electric vehicles (BEVs).

The company’s multifunctional Stator Isolator achieves this by preventing the transmission of axial, radial and torsional vibrations from the stator into its housing.

In traditional BEVs, torque ripples are transmitted from the e-motor to the gearbox, eventually reaching the vehicle’s body through the motor mounts. Ripples are also transmitted through the side shaft and into the wheel, creating an array of NVH-related issues, including airborne noises within the cabin.
