Ansys simulation tools enabled the development team to test the performance of new, nontraditional materials without investing in full physical prototypes

Industrial motors are ubiquitous products that work behind the scenes in every production facility around the world. Motors are used in all industrial fields and account for over 68 percent of the electrical energy used in manufacturing and process plants. However, the demand for more reliable, energy-efficient motors that provide higher levels of power and a broader range of performance is challenging the designers and manufacturers of rotating electrical systems. Dramatic innovations in electrical systems are underway to increase the energy efficiency of the millions of industrial motors that power fans, pumps and compressors used around the globe.

The targeted improvements represent a significant percentage of the world’s overall energy usage. A longtime leader in industrial motor design, TECO-Westinghouse continues to produce groundbreaking electrical machines that operate at new levels of speed and energy efficiency.

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.

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 Icepack). 

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. It contains manufacturer libraries for common components.

PExprt is an analytics-based solution that 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.
