Ansys Maxwell


Ansys Maxwell is a 2D/3D simulation software for low-frequency electromagnetic fields that adopts the finite element method (FEM) to simulate the accurate transient response of non-linear electromagnetic fields. It is used for the design and analysis of electrical machinery, transformers, sensors, and other electromagnetic equipment. It also comes with an expert design tool (RMxprt/PExprt) for the rotating machinery and transformers, which helps the users to quickly model and analyze. It has an outstanding connecting interface with Ansys Twin Builder, with which the integrated simulation of electromechanics can be seen by connecting the control, driving, and feedback circuits provided by Twin Builder.

Product features
Expert modeling tool
Expert design tool (RMxprt/PExprt) included for the rotating machinery and transformers, which can help users to quickly model and analyze.
Circuit integration simulation
It can be connected with Ansys Twin Builder in series, integrating the motor control, drive, and receiving circuits, to conduct loop simulation in the software environment.
Hardware in-the-loop (HIL) structure
Maxwell can export the 2D/3D motor models as ECE (Equivalent-Circuit Extraction) equivalent models into the OPAL-RT instant simulation platform to conduct HIL instant simulation.

Multiphysics coupling
The Ansys simulation field includes multiphysics fields, such as electromagnetic, heat, fluid, solid, and system, etc., and multiphysics coupling simulation can be conducted in Ansys Workbench. The temperature increase can be converted from the motor loss in Maxwell, and the heat transfer, deformation, harmonic vibration, noise, and other multiphysics interactions can be calculated when coupled with Fluent and Mechanical.
