- Bi-Directional CAD Integration
- Electric Drive Modeling
Maxwell offers trusted simulation of low-frequency electromagnetic fields in industrial components. It includes 3-D/2-D magnetic transient, AC electromagnetic, magnetostatic, electrostatic, DC conduction and electric transient solvers to accurately solve for field parameters including force, torque, capacitance, inductance, resistance and impedance. Some key technological features include:
- Reduced-Order Modeling
- Slice-Only Solving
- Co-sim Transient Performance
- Automatic Adaptive Meshing
- 2D and 3D EM Solvers
- Component to System
Slice-only technology enables a cyclic repeatability simulation technique for electric motor applications. The analysis has been improved by efficiently solving just a slice of the motor, employing non-planar boundary conditions, using symmetric mesh and replicating results to the full model. To learn more about how “slice-only” technology helps simulate complex electric motors, read the blog: How to Model and Simulate Complex Electric Motors.
Customizable modeling capabilities, automatic adaptive meshing and advanced high-performance computing technology allow designers to solve complete high-performance electromechanical power systems. Automatically generate nonlinear equivalent circuits and frequency-dependent state-space models from field parameters that may be further used in system and circuit simulation to achieve the highest possible fidelity on SIL (software-in-the-loop) and HIL (hardware-in-the-loop) systems. Ansys simulation technology enables you to predict with confidence that your products will thrive in the real world.

Maxwell is an industry-leading electromagnetic field simulation software for the design and analysis of electric motors, actuators, sensors, transformers and other electromagnetic and electromechanical devices.
Automatic, Adaptive Meshing
A key benefit of Ansys Maxwell is its automatic adaptive meshing techniques, which require you to specify only the geometry, material properties and the desired output to obtain an accurate solution. Ansys Maxwell’s meshing process uses a highly robust volumetric meshing technique and includes a multithreading capability that reduces the amount of memory used and accelerates time to solution. This proven technology eliminates the complexity of building and refining a finite element mesh and makes advanced numerical analysis practical for all levels of your organization.
Multiphysics Coupling Workflow
Maxwell’s electromagnetic field solvers are linked through Ansys Workbench to easily set up and analyze complex coupled-physics behaviors such as deformed mesh feedback structures, stress and strain feedback on magnetic properties, EM fluids and acoustics.
Advanced Magnetic Modeling
Perform advanced simulation calculations such as core loss calculations, vector hysteresis, four-quadrant simulation for permanent magnets, magnetostriction and magnetoelastic analysis, Litz Wire Loss and manufacturing effects on loss computation.
Specialized Design Interfaces
Electric machines and power converters require significantly different design criteria and simulation, which is why Ansys Maxwell provides specialized interfaces for each.
In addition to providing classical motor performance calculations, RMxprt automatically generates geometry, motion and mechanical setup, material properties, core loss, winding and source setup for detailed finite element analysis in Ansys Maxwell.
A multi-domain power electronics simulator for electrical, magnetic, mechanical, fluid, and thermal systems that seamlessly integrates three fundamental component libraries: circuits, block diagrams, and state machines. Simplorer provides an integrated analysis thanks to its connection with EM (Ansys Maxwell, Ansys PExprt, Ansys RMxprt, Ansys Q3D, Ansys HFSS) and thermal tools (Ansys Fluent, Ansys Icepak).
Simplorer also includes the ability to characterize high fidelity power semiconductor models for thermal and EMI/EMC simulations. In addition, Simplorer’s model libraries include VHDL-AMS capability and existing controls systems and customer developed models.
Power Electronics Expert (PExprt) is a magnetic design and optimization tool for ferrite transformers and inductors, including multi-winding transformers, coupled inductors, and flyback components. PExprt’s template-based interface for transformers and inductors can automatically create a design from voltage waveform or converter inputs. The auto-design process considers all combinations of core shapes, sizes, materials, gaps, wire types and gauges, and winding strategies to optimize the magnetic design.
It contains manufacturer libraries for common components. It also combines FEA-based solutions to include skin and proximity effects and gap effects due to magnetic fringing. Additionally, it calculates winding losses, core Losses, R, L, C parameters, and temperature rise and couples to Simplorer using a frequency-dependent netlist for the simulated component.
