Computing Loss, Temperature, and Efficiency in Electric Motors
Follow along as we investigate the variation of iron and copper losses, the resulting temperature rise, and its effect on the efficiency of a permanent magnet machine.
Voltage and Ground When Modeling Wave-Like EM Fields
We continue our discussion of voltage and ground by defining and interpreting these terms for sinusoidally time-varying electromagnetics models.
Do Voltage and Ground Exist?
Remember how the terms “voltage” and “ground” were taught in your university electrical engineering classes? Get a precise definition (in terms of modeling computational EM problems) here.
How to Model a Hall Effect Sensor with COMSOL Multiphysics®
Basic working principle of a Hall effect sensor: A nearby magnetic field deflects the path of current through a semiconductive sensor, which causes a measurable change in potential.
Analyzing Electric Motor and Generator Designs with COMSOL®
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
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
Electromagnetics simulation can be used to predict and investigate magnetic field exposure around power transmission lines and other electrical infrastructure.
