NVH (noise, vibration, and harshness) analysis is a critical aspect of electric motor design, particularly in applications where quiet operation is an essential design parameter. FEA-based simulation design for electromagnetic multiphysics environments provides significant benefits for NVH analysis of electrical machines and transformers.
FEA and multiphysics simulation tools can be used to analyze the vibration and noise levels produced by electric motors and transformers under various operating conditions. This analysis can help our designers identify the sources of vibration and noise, and optimize the motor or transformer design to reduce these levels.
In addition to traditional vibration and noise analysis, FEA and multiphysics simulation tools can also be used to analyze more complex phenomena such as electromagnetic-induced vibrations and acoustic noise. By simulating the electromagnetic fields and their interaction with the motor structure, designers can identify potential sources of vibration and noise and optimize the design to reduce these effects.
NVH analysis is particularly important for manufacturers of motors used in hybrid and electric vehicles, where noise and vibration levels can have a significant impact on the overall driving experience. In addition, NVH analysis is also critical for appliances and commercial transformers, where quiet operation is essential.
