Low-frequency electromagnetic simulation

Simcenter low-frequency electromagnetic simulations allow you to explore designs to meet performance and make timely decisions in product development, reducing the number of physical prototypes needed.

Elevate your low-frequency electromagnetics simulation

Go faster and explore the possibilities
With Simcenter E-Machine Design you can design, test, review and redesign rapidly. With its fully parametrized templates of the most common motor and generator types, an engineer can produce an initial design in just a few minutes. With full compatibility with HEEDs, the chosen parameters can be investigated or optimized in a design of experiments (DoE) study. With a strong connectivity to Simcenter STAR-CCM+, you can perform further analysis with advanced engineering applications.

Model the complexity
Import your e-machine CAD file directly into Simcenter E-Machine Design, where you can optimize your design features, such as coil winding, and benefit from an extensive electromagnetic materials library. With its high-level finite element analysis (FEA) simulation and connectivity to Simcenter MAGNET, an engineer can fine-tune the details of their design with static, time-harmonic, transient and thermal solvers.

Stay integrated
Simcenter 3D low-frequency electromagnetics allows you to create and edit Simcenter MAGNET models in the Simcenter 3D graphical interface with native NX CAD software. Use and define sophisticated magnetic materials and define properties, boundary conditions and loads, including loads using an integrated 1D circuit modeling tool.

Low-frequency electromagnetics capabilities

Dedicated interface for e-motor and e-generator designers

The dedicated e-generator and e-motor design software, Simcenter E-Machine Design offers a purposely developed interface for e-motor and e-generator designers. It offers numerous of parametrized templates covering the most common e-machines topologies, including radial and axial flux machines.

The simulation workflows are fully automated so that the users can simulate the e-motor or generator performance in a few clicks. This allows designers to evaluate 100s of designs per week much faster and without being simulation experts.

Many templates are available including those for a range of motor types, this image shows the motor type selection window

Magneto-thermal simulations

Allows you to couple magnetic and thermal physics as early as you desire in the design cycle. By doing so, engineers can avoid failures and improve the life of the motor. When you consider that for every 10 Celsius (°C) above the designed temperature, the expected product life is reduced by 50 percent, frontloading multi-physics issues are critical to streamline the design process.

Advanced electromagnetic material modeling, including advanced core losses and demagnetization

The accuracy of low-frequency EMAG simulations is highly dependent on material data and thorough handling of material property dependencies. Simcenter EMAG advanced material modeling accounts for nonlinearities, temperature dependencies, 2nd quadrant handling of permanent magnets, hysteresis loss and anisotropic effects. This makes it possible to analyze effects such as demagnetization in permanent magnets to verify their service life, analyze frequency-dependent losses in component laminations while reducing solution time. Account for all losses to ensure an accurate energy balance. For ease of use, the software includes an EMAG material library with over 400 materials available.

Circuit and system modeling

System-level or model-based analysis requires accurate sub-component models to account for interactions and local transients that affect the overall system behavior.

Simcenter low-frequency EMAG includes capabilities such as native circuit simulations, connections for co-simulation and exporting of 1D system models for Simcenter Flomaster, Simcenter Amesim, Xpedition AMS and other platforms.
