Configurator How-To Guides
The Turncircles Configurator lets you design a custom coreless axial-flux PMSM from your application requirements, check it with fast analytical calculations, and then confirm it with finite-element simulations. These guides take you through every card on the configurator page, one parameter at a time.
All screenshots come from one example design, "Configuration 150W": a single-stack, 12-pole motor with a 60 mm rotor, rated 0.10 Nm at 6000 RPM on a 12 V DC supply. It has five simulation revisions and a generated efficiency map.
How the simulations work
The finite-element results behind every revision come from a full open-source FEA pipeline: Open CASCADE builds the exact 3D motor geometry, Gmsh meshes it, and ElmerFEM solves the electromagnetic field problem. Nothing here is a simplified lookup table — every revision you submit runs a real 3D finite-element solve on the geometry you configured.
The guides
| # | Guide | What you'll learn |
|---|---|---|
| 1 | Getting started | Page layout, toolbar, tooltips, colour-coded warnings, and the recommended workflow |
| 2 | Mechanical output properties | Speed, torque, power and stacks |
| 3 | Electrical supply properties | DC bus voltage, back-EMF matching, stack connection, current density |
| 4 | Rotor properties | Diameters, magnets, air gap, magnet span, poles, 3D model |
| 5 | Stator properties | PCB winding: turns, layers, copper, traces, parallel paths |
| 6 | Analytical results and indicative price | Efficiency, air gap torque, losses, resistances, pricing |
| 7 | Running simulations | Accuracy levels, revisions and tokens |
| 8 | Reading simulation results | Back-EMF, Ke, harmonics, current and max-current sweep |
| 9 | Efficiency maps | Generating a map, performance metrics, data table, per-point loss breakdown and waveforms, extra operating points |
| 10 | Comparing revisions | Using Compare to pick the best revision |
Suggested reading order
If you're new to the configurator, read guides 1–6 in order. They follow the page from top to bottom and match the order you set parameters in. Read 7–10 once you have a design worth simulating.
