Industry-Leading E-motor Acoustic Simulation
E-motor NVH and Active Sound Design for EV
Ansys Solutions for acoustics provide a complete multiphysics workflow for e-motor noise, vibration and harshness (NVH), as well as active sound design for electric vehicles, enhancing driver and passenger safety and comfort.
Active Sound Design for Electric Vehicles (EV)
Electric vehicle (EV) and autonomous vehicle (AV) manufacturers create signature sounds for their cars (including engine noise) to enhance vehicle appeal and give listeners a feel for the speed and acceleration. Using cutting-edge sound enhancement techniques, automakers are introducing new, customized sounds for their vehicles. These techniques augment natural vehicle sounds by playing synthesized sounds synchronized with the vehicle's real-time data over the vehicle's speakers. Ansys delivers in-vehicle sound design and tuning that is designed to predict, test and validate the future soundscape of vehicles in real-world driving conditions, to ensure that EVs provide the optimal sound experience.
E-Motor Noise, Vibration and Harshness (NVH)
Simulating the noise, vibration and harshness (NVH) of an electric motor is important for proper electromagnetic (EM) and vibro-acoustic design of electric vehicles (EVs). Ansys’ solutions can characterize the NVH effects of an electric motor early and accurately in the design cycle to improve vehicle performance and safety. These solutions lower development costs and help support electric mobility (e-mobility) — an application resulting from electrifying transportation. Ansys' solutions enable EV carmakers or other e-motor integrators to optimize the sound perception and performance, improve customer satisfaction and gain competitive advantage in the transportation and industrial sectors.

Acoustic Simulation Transforms Design and Improves User Experience
Whether it's reducing vibrations in a household product or an electric vehicle, acoustic simulation improves the sound of our world. Sounds can be a product benefit or an annoyance, creating a strong emotion and reinforcing a product's brand identify. This is especially true with EVs. Ansys tools enable automakers to design the perfect acoustic experience for their vehicles.
Electric Motor Design & Simulation
Whether you're designing an electric motor for an electric vehicle that needs to be small, efficient and quiet, or for an industrial application where size and sound are not of major concern, it is critical to simulate electric motors early in the design process. Ansys offers a complete workflow that progresses from design sizing options to detailed electromagnetics and thermal and mechanical analyses of the motor. Coupled electromagnetic-thermal-stress and vibro-acoustics simulation of the motor using Ansys tools results in a high-fidelity, accurate and robust design that is optimized for performance, cost and efficiency.
