InfiniX goes radial: more compact, more powerful, measurable torque

·4 min read

After the linear demonstrator, designed to isolate and verify the basic principle, here is the next step: a radial architecture, more compact, more powerful, and above all designed to deliver a directly measurable and usable torque — not just a proof of concept spinning with no load.

What changes with this version

The two visible cylindrical blocks are the stator and the rotor, each fitted with the neodymium permanent-magnet-core electromagnets described in the publication — the same superposition-cancellation architecture, but assembled this time in a radial rather than linear configuration. This layout brings the active elements closer together in a smaller volume, for a power density higher than the linear demonstrator.

The drive is coupled to an external servo motor through a gear train — which opens the door to an adjustable speed, controllable to suit the measurement or the demonstration, up to energy recovery and battery charging.

Why measurable torque changes everything

A large share of the objections received in recent weeks focused on one precise point: the difference between free rotation and real, usable mechanical work. This radial version is designed to answer that demand directly — a torque you can instrument, load and verify, not just watch spinning.

The evolution of the test bench

The very first InfiniX measurements (absence of back-EMF, net torque, energy balance) were made on the original test bench. This radial version is its direct evolution: more compact, more powerful, spinning faster than the bench prototype, with far fewer parts — for a simpler and more reliable architecture. The measured principle remains identical. Only the engineering has progressed.

About the energy gain

An energy surplus was observed during bench tests (200 J injected → 160 J Joule losses + 40 J recovered, with ~40 J of kinetic energy measured independently). On this motor, the mechanical energy at the shaft comes from the “free” torque supplied by magnet repulsion once the circuit is open — a real observation, documented in the publication. But a rigorous energy balance of the complete system, confirmed by an independent third party, remains work in progress. This motor is designed to observe both sides of the subject: the absence of braking, measured, and the question of the overall gain, still open.

What it remains: a verification tool, not a conclusion

As with the linear demonstrator, the aim is not to proclaim a result, but to give those who want to verify the means to do so — with a more advanced object, closer to real use. The same rules apply: technical content, reserved for informed users, in the same spirit of open replication as everything else in this work. This motor remains educational: it is meant to study the principle, not to power anything.

Getting the radial motor

Each motor is assembled and tested one by one, at a rate of one unit every two weeks. The bank transfer confirms the order and places you in the production queue; free collection at the warehouse (with a demonstration) or home delivery (€100 in France and neighbouring countries, €150 in the UK). No membership is required to buy.

Warning — educational use only

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.
