From principle to measurable torque

A large share of the objections we received focused on one precise point: the difference between free rotation and real, usable mechanical work. This radial version answers that demand directly. The two 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 radially rather than linearly. The active elements are brought closer together in a smaller volume, for a higher power density. The drive is coupled to an external servo motor through a gear train: speed becomes adjustable, controllable to suit the measurement or the demonstration.

Accessible measurement points to verify it yourself with an oscilloscope.

About the energy gain

An energy surplus was observed during bench tests (balance: 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. This is 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 — not a definitively established result. This motor is designed precisely to observe both sides of the subject: the absence of braking, measured, and the question of the overall gain, still open.

How ordering 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 orderOn receipt of the transfer, your order enters the production queue: one motor is built every two weeks, assembled and tested one by one. We tell you your position and the expected collection date.
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).

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.

Want to understand in detail?

The motor implements the principle described in the two open-access publications: the “InfiniX for Dummies” guide (16 pages, no equation before chapter 10) and the full scientific publication with protocol and measurements.
