February 18, 2016

Learn how to use the Rotating Machinery, Magnetic interface in COMSOL Multiphysics® to model a 3D generator, and then compare our results with an analogous 2D model. Part 2 of 2.

Modeling Linear Motors or Generators in COMSOL Multiphysics

October 6, 2015

The Rotating Machinery, Magnetic physics interface available in the AC/DC Module is used to model rotating machines such as motors or generators. When modeling the linear or tubular device with the Magnetic Fields and the Moving Mesh physics interfaces, it is appropriate to use a customized linear periodic boundary condition. In this blog post, we will explore how to customize the linear periodic boundary condition and model the tubular generator that is used for wave energy.

How to Model Magnetic Bearings in COMSOL Multiphysics®

July 28, 2015

Magnetic bearings are used in many industrial applications, including power generation, petroleum refinement, turbomachinery, pumps, and flywheel energy storage systems. Unlike mechanical bearings, these types of bearings support moving loads without physical contact through magnetic levitation. Valued for their frictionless operation and ability to run without lubrication, magnetic bearings are a low-maintenance alternative to mechanical bearings with a longer lifespan. Learn how to calculate design parameters like magnetic forces, torque, and magnetic stiffness using the COMSOL Multiphysics® software.
