Slice-only Technology

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.

Maxwell Capabilities


Key Features

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.

  • Low-frequency EM simulation
  • Automatic, adaptive meshing
  • Multidomain system modeling
  • Expert design interfaces
  • Optimetrics
  • Granta Materials Data
  • ISO 26262 compliant

A key benefit of 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. 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.

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.

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.

Electric machines and power converters require significantly different design criteria and simulation, which is why 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 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 (Maxwell, PExprt, RMxprt, Q3D, HFSS) and thermal tools (Ansys CFD, 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.

You can output transient electromagnetic forces from Ansys Maxwell into Ansys Motion, extending electromagnetic interaction to rigid body dynamics to enhance the overall noise-vibration solution.

A new Maxwell transient solver provides multiterminal conductor support on a single conduction path.

Ansys Maxwell is an electromagnetic field solver for electric machines, transformers, wireless charging, permanent magnet latches, actuators, and other electromechanical devices. It solves static, frequency-domain and time-varying magnetic and electric fields. Maxwell also offers specialized design interfaces for electric machines and power converters.

You can learn about Ansys Maxwell in several different ways depending on whether you are an existing customer or a student or non-customer.

This free course, available on our Ansys Innovation Courses Site, you will learn the basics of Ansys Maxwell design and the LF simulation workflow.

These Maxwell courses are available to Ansys Customers.

Ansys Maxwell interfaces with Ansys Motor-CAD, Ansys HFSS, Ansys Icepak, Ansys Mechanical, Ansys CFD, Ansys Motion, Ansys TwinBuider and Ansys optiSLang.

Click Maxwell>Draw>Region

  • This displays the Region dialog box. You can define the region padding as a percentage, relative position, or absolute position.
  • For the Padding data, select either Pad all directions similarly, Pad individual directions, or Transverse padding.

To download Ansys Maxwell, you must be an Ansys customer and have access to the Customer Portal. Ansys Maxwell is included in the Electronics software bundle and is also included in the free Ansys Student bundle.

Ansys Maxwell can be used in a variety of applications, including electric machines, transformers, wireless charging, permanent magnet latches, actuators, sensors, conveters, electromagnetic shielding, and other electromechanical devices.

To solve for a capacitance, inductance, impedance, or conductance matrix:

    • For 3D Electrostatic, 2D and 3D Magnetostatic, 2D and 3D Eddy Current designs, select or clear the Include check box for any of the listed sources.
    • For Maxwell 2D designs, the return path for each source may be specified. By default, the return path is at infinity; however, any conductor with a source specified can act as the return path.
    • For 2D Electrostatic, 2D and 3D DC Conduction, and 2D and 3D AC Conduction, select or clear the Signal or Ground check box for any of the listed sources. Grounded terminals are treated as reference voltages with zero voltage values.
    • Excitations checked as Signal will be in the matrix (excited one at a time with 1V during the parameters extraction process). Those excitations checked as Ground will be kept at 0 V and will not be part of the matrix. Any excitations not checked will not be considered.
