Introduction to Electric Motor NVH with Ansys Solution


Noise, vibration, and harshness (NVH) in electric machines can come from many sources and has direct effects on the perceived quality of a product. As one noise source is reduced, other sources become increasingly important. The design of a high-performance electric machine with good sound characteristics requires a holistic engineering approach involving both the magnetic design of the motor and structural/acoustic design of the housing and supports.  This design process can be analyzed with simulation, which can include simultaneous optimization of motor and housing parameters to achieve noise goals. 


Follow this course to learn about the physics and background of the ANSYS approach for NVH simulation and experience hands-on workshops to illustrate how easily this workflow is implemented using ANSYS simulation tools.
