The InfiniX motors: from the linear demonstrator to the radial motor, the complete guide
On 18 July 2026, Christophe Tétard showed a motor that does not brake itself. Since then, one question keeps coming back: “How can I verify it?” Here is the answer, in two objects. A linear demonstrator, simplified to the extreme to isolate the principle and reproduce it at home. And a radial motor, more compact, more powerful, with a torque you can load and measure. This article explains everything: what they do, what they do not claim, how to get them — and where to find the plans.
The two InfiniX motors presented by Christophe Tétard.
A three-sentence reminder: what InfiniX changes
Every electric motor brakes itself as it turns: that is the counter-electromotive force, or back-EMF, described by Faraday in 1831 and present in every motor in the world. InfiniX bypasses that brake in two moves: make a magnet invisible (a coil around a neodymium magnet cancels its field exactly, from the outside), then break the circuit at the right moment — not just cut the current — so that the natural field reappears facing a second magnet in repulsion. It is no longer the winding that pushes: two magnets repel each other, without the classic counter-current.
InfiniX does not claim to create energy or to violate any conservation law. What is claimed — and measured — is the absence of the classic internal brake. An energy surplus was observed on the bench; its rigorous study, confirmed by independent third parties, is still work in progress. That is precisely why these motors exist: so that you can measure.
The two reference publications, open access
A 16-page guide in plain language — no equation before chapter 10 — and, for those who want the full protocol, formulas and measurements, the complete scientific publication (FR/EN). Everything the motors implement is described there.

Two motors, two missions
| Linear demonstrator | Radial motor | |
|---|---|---|
| Purpose | Isolate and verify the basic principle, with your own hands | Observe a real motor: torque, speed, balance |
| Architecture | 2 stages of neodymium-core electromagnets, open structure | Cylindrical stator + rotor, resonant Class E, gear train to a servo motor |
| What is measured | Field cancellation, repulsion force, absence of back-EMF | Same + net torque (Prony brake), 500 W at the shaft, consumption in pulsed mode |
| Production | To order, after transfer | One unit every two weeks |
| Handover | Free collection at the warehouse (La Souterraine) or home delivery: €100 in France and neighbouring countries, €150 in the UK | |
| Price | €800 | €1,200 |
| Plans | STL + PDF reserved for members | Not released (prototype, patent filed) |
| Audience | Informed users — educational and experimental use only | |
1. The linear demonstrator: verify it yourself
This is the simplified version, designed so that anyone can reproduce the exact setup and observe, with their own instruments, the cancellation of a magnetic field by superposition and then the force that reappears when that field is restored. Not a black box: the setup to build yourself — or to buy assembled, for those who would rather not build.
You no longer need to believe anyone. You need a bit of equipment, a bit of rigour, and the will to measure. Read the article about the linear demonstrator →
The complete plans, for members
The STL files of every part and the build PDF are made available to Projet Atlas members. This is not a price meant to profit from curiosity: it is what allows the association to exist, to produce resources and to support the next steps of this work. Once you are a member, your Alexandrie account is created automatically and the downloads await you in the members-only article.
2. The radial motor: real, measurable torque
Many objections focused on one precise point: free rotation is not usable mechanical work. The radial motor is the answer. Same principle, same neodymium-core electromagnets, but assembled radially: the active elements are brought closer together in a smaller volume, power density rises, and an external servo motor coupled through a gear train makes the speed adjustable. Result: 500 W at the shaft, a net positive torque on a Prony brake, and measurement points accessible to an oscilloscope.
It remains what it is: a verification tool, not a conclusion. The measured principle is the same as on the original bench; only the engineering has progressed. Read the article about the radial motor →
How a purchase works
- You place your order onlineCustomer account or guest checkout: you do not need to be a member of the association to buy a motor.
- You pay by bank transferThe bank details (Revolut) are shown at the end of checkout and in the confirmation e-mail. Put your order number as the transfer reference.
- The transfer confirms the orderThe transfer is what confirms the order: for the linear motor, it triggers the scheduling of your unit; for the radial motor, it places you in the production queue (one motor every two weeks).
- You receive your motorYour choice at checkout: free collection at the warehouse (5 rue Hyacinthe Montaudon, 23300 La Souterraine (Creuse, France), by appointment, with a demonstration and handover of the running motor) or home delivery (€100 in France and neighbouring countries, €150 in the UK).
No membership is needed to buy a motor. Membership is for something else: access to the plans, to members’ articles, to workshops — and a say in the association’s decisions.
This motor is sold for educational and experimental use only: it is meant to study and observe the implementation of the principle described in the scientific publication. It is not designed for real-world use nor for integration into any system, equipment or production. It is intended for informed users (basic electronics, practice with measuring instruments). Faraday Labs, the Projet Atlas association and the designer decline all responsibility for any use outside this scope. The buyer takes possession of the object knowingly and at their own risk.
Why all of this is open
Because a discovery that stays in the hands of a single man, however convinced he may be, is worth nothing in the face of science. A discovery that dozens, hundreds of people reproduce on their own, with their own measurements, their own doubts, their own results — that starts to look like a truth that can no longer be ignored. That has been the spirit of Projet Atlas from day one: open replication matters more than any claim, including the inventor’s.
“It is no longer my move. It is up to anyone who wants to reproduce the experiment and verify it for themselves.”
— Christophe Tétard
An assembly video of the linear demonstrator, in partnership with NEXUS magazine, is in preparation.
