A unique test bench for anyinterfaces track/vehicle(traction/guidance, wear testcontact…), located in Grenoble(France).

Designing of U-Shaped Linear Induction Motor (U-LIM) for specific applications.

Traction / braking / Launcher system, above 1 MW / 300 km/h.

U-CARS® : U-LIM Containers Autonomous Rail Shuttle

U-TRACE® : U-LIM Tracked Air Cushion Equipment for passenger transportation

U-LAUNCHER® : Electromagnetic Aircraft Launcher and ground booster.

A world unique test track equipped to validate full scale high power linear traction systems.

The wheel

The large diameter of the wheel test bench (13m diameter) offers almost 41m peripheral track, with an inertia equivalent of a 25tons vehicle. Maximum safe speed 400km/h, Currently conditioned for 300km/h.

The purpose

The wheel is used to validate full scale traction guidance systems, and any interfaces for contact or contactless vehicle (energy transmission, wear test contact, reliability and safety test…), up to very high speed.

TACV Lab is structured to design and validate U-linear motor (U-LIM) drive systems for special applications such as linear boosters and high speed linear brakes.

Calculation code and designing data base (exclusivelicense right of the UGE / University Gustave Eiffel) issued from several full scale tested motors.

Today about 200 U-shaped linear induction motors are operating in several national city airports (Nantes, Bordeaux, Bastia).

A world unique test facility for the development and validation of full scale linear motors powered by their traction chains and safety brake system, equipped with track-vehicle interfaces, including guidance system.

Design and validation of booster-launcher systems using linear motor drives for special applications.


U-LIM Containers Autonomous Railway Shuttle
