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 SPEED you can design, test, review and redesign rapidly. With its six 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 Motorsolve, 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

AC electromagnetic simulation

AC electromagnetic simulations are based on a single frequency, which reduces the simulation time. With this approach, you can simulate electromagnetic fields in and around current-carrying conductors, in the presence of isotropic materials that may be conducting, magnetic, or both. This accounts for displacement currents, eddy-current and proximity effects, which are important in hotspot analysis.

Advanced electromagnetic material modeling

The accuracy of low-frequency electromagnetic simulations is highly dependent on material data. Simcenter electromagnetic advanced material modeling accounts for nonlinearities, temperature dependencies, demagnetization 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 thin parts while reducing solution time, and account for all losses for an accurate energy balance.

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

Electromagnetic-motion simulation

The electromagnetic simulation of transient fields can include motion. It is possible to simulate rotational, linear and arbitrary motion with six degrees of freedom (X, Y, Z, Roll, Pitch and Yaw). This is available for an unlimited number of moving components, induced currents and mechanical interactions. 

The mechanical effects include viscous friction, inertia, mass, springs and gravitation, as well as constraints on movement imposed by mechanical stops. Arbitrary load forces can be specified as a function of position, speed and time. Induced currents due to motion are taken into account.

Transient electromagnetic simulation

Permits the simulation of complex problems that involve time-varying arbitrary-shaped current or voltage sources and outputs with nonlinearity in materials and frequency-dependent effects. This includes oscillations in electromechanical devices, demagnetization in permanent magnets, switching effects, eddy-currents-induced torque, skin and proximity effects.
