Comparison Table
JMAG-Designer
vertical specialistFinite element simulation software focused on electric machine design and analysis.
Motor design parameterization that keeps winding configuration and geometry edits linked to torque and back-EMF evaluation runs.
JMAG-Designer focuses on motor design workflows that connect electromagnetic and thermal studies around winding configuration and geometry refinement. It supports a practical modeling loop for stator geometry and rotor topology so design changes can be iterated quickly across analysis cases.
The toolset also targets common evaluation needs such as back-EMF, torque ripple, and cogging torque outputs tied to machine operating conditions. JMAG-Designer is most distinct where engineers want integrated design-to-analysis tooling without switching between separate CAD and solver environments for each study step.
- +Iterative motor design workflow ties geometry changes to analysis outputs quickly
- +Built-in evaluation outputs include torque ripple and cogging torque for typical motor metrics
- +Winding configuration handling supports practical design variants without custom scripting
- +Supports multiphysics study setup that keeps electromagnetic and thermal contexts connected
- –Deep automation requires more setup effort than GUI-only parameter sweeps
- –Import and geometry cleanup can be time-consuming when STEP detail is inconsistent
- –Transient solver runs can increase turnaround for large meshes and many design points
- –Extensibility beyond common motor workflows depends on external tool integration

Best for: Fits when mid-size engineering teams need an integrated design-to-electromagnetic workflow with repeatable analysis outputs for motor optimization.
QuickField
SMBFinite element analysis software used for electromagnetic problems including motor cross-sections.
QuickField's linked problem workflow transfers computed fields between magnetic, electric-current, and heat-transfer studies.
QuickField supports motor investigation through planar and axisymmetric geometries, editable material properties, nonlinear magnetic curves, and transient excitation. Engineers can calculate field distributions, forces, flux density, current density, and temperature across linked studies. DXF import also helps convert existing two-dimensional lamination drawings into simulation geometry.
The two-dimensional workflow limits end-effect analysis, three-dimensional rotor behavior, and detailed cooling representation. Motor-specific winding templates and automated design searches are less developed than in dedicated motor design suites. QuickField fits early motor architecture comparisons where rapid cross-section changes matter more than full machine validation.
- +Planar and axisymmetric motor sections support fast geometry iteration
- +Nonlinear materials and transient analyses handle changing excitation
- +DXF import reduces redraw work for existing laminations
- +External scripting supports repeatable parameter studies
- –Two-dimensional modeling omits end effects and full three-dimensional rotor behavior
- –Motor-specific winding and performance templates are limited
- –Linked problem types require manual setup and result transfer
- –Native automated winding optimization is not a core workflow

Best for: Fits when engineers need scriptable two-dimensional motor studies with linked magnetic and thermal calculations.
FEMM
freewareFree finite element software for low-frequency electromagnetic and electrostatic simulation.
JMES export turns computed results into a structured output that can be compared across design iterations.
FEMM enables a workflow built around drawing or importing geometry, assigning materials, and solving for field quantities such as flux density distributions and derived performance metrics. DXF import supports bringing in CAD-like drawings into a 2D mesh workflow without converting everything into a custom mesh definition. JMES export supports moving computed results into a form that can be post-processed or compared across design iterations.
A key tradeoff is that FEMM’s core capability centers on 2D magnetics rather than multiphysics coupling, so thermal and transient system dynamics require other tools. FEMM fits best when evaluating magnetic circuit behavior early, like comparing rotor topologies or stator geometry options for torque-related trends before committing to heavier multiphysics simulation.
- +Fast 2D magnetics workflow for iterative stator and rotor geometry edits
- +DXF import reduces time spent rebuilding geometry in the mesher
- +JMES export supports structured results post-processing pipelines

How to Choose the Right Motor Design Software
Motor design software options mainly separate on Simulation fidelity and workflow fit. We look for Simulation fidelity and Model import/export because they change how close results get to real motor behavior and how fast you can iterate.
Simulation fidelity for motor performance
Why it matters
Simulation fidelity for motor performance matters because design decisions depend on how well losses, torque behavior, and operating points match the real motor. If fidelity is weak, optimization can move you in the wrong direction.
How to check
Ask for a sample project with known results and run it to see whether torque and speed/efficiency trends match the documentation. Then change one design input (like load point or geometry dimension) and confirm the outputs move in a physically consistent way.
Iteration workflow from spec to results
Why it matters
A clear iteration workflow from spec to results matters because motor work often cycles through constraints, tradeoffs, and reruns. Poor iteration flow can waste time even when the simulator is accurate.
How to check
During a demo, follow the path from entering a target requirement to producing final plots. Time how many steps it takes to modify a key input and regenerate results, and check whether intermediate states can be reused.
CAD model import and clean export
Why it matters
CAD model import and clean export matters because motor design rarely starts from a blank file. If import/export is messy, you’ll spend effort fixing geometry rather than exploring design space.
How to check
Request an example workflow using the CAD format you already have. Check whether units, scale, and coordinate orientation stay consistent, and verify that exported geometry opens without gaps or failed references.
Parameter sets and design variables control
Why it matters
Parameter sets and design variables control matter because motor studies compare controlled variants. If parameters can’t be managed cleanly, you lose traceability between what you changed and what improved.
How to check
In a demo, create two variants by changing a small number of parameters and confirm the software keeps a clear record of which values produced each result. Look for a way to name and re-select parameter sets later.
Result plots and reporting for review
Why it matters
Result plots and reporting for review matter because teams need to compare runs, justify choices, and communicate findings. If plots can’t be customized or exported reliably, review becomes manual and error-prone.
How to check
Ask to export key plots and a short report package from one run. Confirm you can choose which charts appear, add annotations, and export them in a format you can paste into internal documents.
Reproducible runs with version control
Why it matters
Reproducible runs with version control matter because motor designs move through review and revision cycles. Without reproducibility, it’s hard to tell whether a change caused a difference or just altered the setup.
How to check
Run the same case twice and confirm outputs are consistent within stated tolerance. Then change a software setting or parameter and show whether the tool tracks what changed alongside the results.
Red flags
- Simulation fidelity looks inconsistent across operating points
- Import/export forces you to manually repair geometry repeatedly
- Results are hard to reproduce or trace back to parameters
Fit by situation
- If we must compare multiple design variants with clear traceability, prioritize parameter sets and design variables control.
- If we need to iterate quickly from target specs to deliverable plots, prioritize iteration workflow from spec to results.
- If our workflow starts from existing CAD and must stay consistent, prioritize CAD model import and clean export.
