    What is NVH in electric motors?
    In an electric motor, the most important NVH phenomenon is the whistling noise, which is caused by the electromagnetic forces and amplified by the powertrain structure. With the current NVH simulation technology, e-motor whistling noise levels can be accurately simulated up to 4500 Hz.

    Why is NVH a problem in electric vehicles?
    But tonal noise originating from the electric motor is a big concern for engineers designing these vehicles. NVH is often felt by any occupant of a moving electric vehicle. At varying motor speeds, NVH is unpleasant and may cause fatigue on the vehicle and discomfort for its occupants. An electric motor is a key segment of the powertrain.

    How can we predict the NVH performance of an electric motor?
    Examples of simulation results are shown which allow us not only to predict the NVH performance, but also to understand better the fundamental NVH behavior of an electric motor. In an electric motor, the most important NVH phenomenon is the whistling noise, which is caused by the electromagnetic forces and amplified by the powertrain structure.

    How can EV engineering improve NVH?
    Combining electromagnetics, structural and acoustic engineering enables engineers to holistically optimize an EV’s NVH. The most important NVH phenomenon for an electric motor is the whining noise caused by electromagnetic (EM) forces, which can be calculated in Ansys Maxwell for both single and multiple motor speeds.
