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. Learn more about how “slice-only” technology helps simulate complex electric motors, read this blog.

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

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, 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. 

RMxprt's template-based interface for transformers and inductors can automatically create a design from voltage waveform or converter inputs. The autodesign process considers all combinations of core shapes, sizes, materials, gaps, wire types and gauges, and winding strategies to optimize the magnetic design.
