A Quiet Revolution: Analyzing Electric Motor Noise via Simulation

March 2, 2021

The sound we hear from electric-powered machines is a multiphysics phenomenon: A motor’s electromagnetic activity sends vibrations through both the machine and the surrounding air.

Analyzing Electric Motor and Generator Designs with COMSOL®

February 16, 2021

Using electromagnetics simulation, you can investigate and optimize the magnetic field distribution, mechanical torque, and iron usage and losses in a permanent magnet motor or generator.

Computing Losses in a Three-Phase Power Transformer

February 4, 2021

Around the world, power transformers are used in power grids for efficient electric power transmission. EM simulation can be used to compute losses in these devices and optimize their designs.

Investigating Magnetic Field Exposure Near Transmission Lines

December 14, 2020

Electromagnetics simulation can be used to predict and investigate magnetic field exposure around power transmission lines and other electrical infrastructure.

5 W’s for 200 Years of Electromagnetism
