Parametric geometry
Radial and axial cross-sections built from main dimensions, with DXF import/export and import of existing .mot models.
FEM design for electrical machines
Design, simulate and document motors — in one application.
AGFEM is a Windows desktop application for the electromagnetic design of rotating electrical machines. Parametric geometry, an in-house 2D FEM solver, winding synthesis, loss, efficiency and thermal models — through to the finished datasheet.
Full feature set. No payment details for the trial.
13 machine topologies
2D FEM in-house nonlinear solver
30 days free trial
650+ automated tests
From a parameter row to a datasheet you can defend
AGFEM joins parametric geometry generation, meshing and a nonlinear 2D magnetostatic solver into one continuous workflow. No patchwork of scripts between CAD, mesher and solver: change the geometry, solve, read the result.
3D view
A spatial view generated from the real 2D contours, with half-section, parametric shaft and end windings.
Winding design
Automatic winding synthesis, slot layout with phase assignment, and one consistent area model from fill factor to wire diameter.
Material database
Laminations, magnets and conductors from MotorCAD databases, including ferrites with the temperature drift of remanence.
Field computation
Flux density, vector potential, current density and magnet field as field plots — plus torque ripple, cogging and open-circuit back-EMF.
Demagnetization check
A check at the temperature, speed and torque you specify, reporting the share of magnet area at risk and mapping the critical region.
Topologies you can compute
AGFEM builds the geometry parametrically. Pick the machine type, set the main dimensions, solve — inner and outer rotor, radial and axial flux.
Surface-magnet PMSM
Surface-mounted and inset magnets, magnetised radially, in parallel or breadloaf-shaped.
SPM outer rotor
The same compute path with the rotor on the outside — typical for hub, fan and drone drives.
IPM, flat embedded magnets
Buried flat magnets with flux bridges — the best-calibrated variant in AGFEM.
Spoke-type IPM
Flux concentration through tangentially magnetised spokes — ferrite magnets included.
V-shape IPM
A pair of magnets in a V, combinable with hooked teeth and an asymmetric tooth tip.
Synchronous reluctance machine
Flux-barrier rotor, optionally PM-assisted with ferrite or NdFeB inside the barriers.
Example library
The software ships with 29 ready-parameterised machines — from an RC servo through the Toyota Prius to an axial-flux disc. Open any of them, run it, and rebuild it into your own design.
Inside the application
Screenshots and results taken from real design projects.
Geometry of the Toyota Prius 2004 (IPM, 48 slots / 8 poles) — built parametrically, dimensions on the left, section on the right.
Winding layout with U/V/W phase terminals and winding factor — synthesised from the slot and pole count.
A 3D half-section built from the real 2D contours — lamination stack, magnets, end windings and shaft.
Flux density of the Prius machine under load, from the 80,832 triangles of the FEM solution — the computed file, not a demo picture.
Honest numbers, not flattering ones
Three rules apply to every computation in AGFEM:
No fudge factors
Every correction factor sits at 1.0. Deviations from measurement are traced to a cause, not tuned away.
Calibrated against measurement
The buried-magnet calibration is anchored to a real customer back-EMF measurement and re-checked automatically whenever the compute path changes.
Errors instead of silent fallbacks
When input data is missing, the calculation refuses to answer rather than quietly guessing a substitute value.
Frequently asked questions
When does the trial start?
With the first activation of the licence key inside the installed software — not at sign-up. So you can download now and start whenever it suits you.
Is the trial limited?
No. Every topology, every tab, every export. After 30 days a licence is needed to keep computing.
Does the computer have to be online?
AGFEM checks the licence at start-up and then once a day. Without a connection the software keeps running for up to 14 days on the last confirmed licence.
On how many computers may I install it?
A named-user licence covers up to two computers belonging to the same person, e.g. a workstation and a laptop. You can release and reassign computers from your account.
How do I cancel?
From your account, through the billing portal, with one click effective at the end of the current month. There is no minimum term.
Are my design data uploaded?
No. Everything is computed locally on your machine. Only the licence check reaches our server — the key, an anonymous device identifier and the application version.
Compute your own machine.
Sign up, download, install — the 30 days only start with the first activation inside the software.
