The manufacturers search engines can't see, part 2

Five French makers of custom motors and mechanisms for aerospace, defense and nuclear: decades of qualified capacity, several pages deep in search.

Oct 9, 2026 4 min read By Procureezy

When we published “The Manufacturers Search Engines Can't See,” we argued that Google rewards visibility, not capability, and that some of Europe's most qualified industrial suppliers rank nowhere near where their track record would suggest. The response confirmed it: procurement teams don't find these companies through search, they find them through referrals, trade shows, and word of mouth passed between engineers. This follow-on names five more. Each is a French manufacturer of custom electric motors, mechanisms, or components for aerospace, defense, nuclear, or industrial clients. Each has operated for decades without a meaningful content marketing budget. And each sits several pages deep in the search results for the exact queries that should surface them first.

Map of France titled 'Five makers. Decades of qualified work. Nowhere on page one.' Pins mark Servat (1990, Lieusaint), 2E Windings (2009, Auxerre), WELCO Industries (1976, Le Poët), ERNEO (2009, Castelnau-le-Lez) and Soterem (1975, Castanet-Tolosan).
The five manufacturers in this article, from the Paris region to the foot of the Alps and the outskirts of Toulouse.

01ERNEO

Founded
2009
Based in
Castelnau-le-Lez, near Montpellier
Builds
Custom electric motors and magnetic systems
Credentials
12 patents · Aerospace Valley member

ERNEO, founded in 2009 and based in Castelnau-le-Lez near Montpellier, designs and manufactures custom electric motors and high-performance magnetic systems for embedded applications. Its range includes high-speed motors running up to 100,000 RPM and motors engineered for cryogenic environments, work that has earned it 12 patents and membership in the Aerospace Valley cluster. The company operates from a 1,100 square meter facility built for everything from prototypes to series production, with backing from the Occitanie region, the French defense procurement agency (DGA), and European funding programs. None of that shows up in a plain web search for a custom electric motor manufacturer in France, where directory listings crowd out companies like ERNEO entirely.

022E Windings

Founded
2009
Based in
Auxerre
Builds
Electric motors, coil windings and assemblies
Credentials
EN 9100 · Safran and Thales as customers

2E Windings, founded in 2009 in Auxerre, manufactures electromechanical components and assemblies, primarily electric motors and coil windings, with capabilities spanning bonding, press-fitting, stacking, welding, soldering, and co-engineering. It holds EN 9100 certification, the quality standard aerospace and defense supply chains require, and counts Safran and Thales among its customers. Production runs from single units to roughly 3,000 units a year, exactly the kind of small-to-medium series work that large motor manufacturers won't take on and search engines rarely index.

03WELCO Industries

Founded
1976
Based in
Le Poët, Hautes-Alpes
Builds
Motor-compressors, motors, fans, blowers and pumps
Credentials
ISO 9001 · EN 9100

WELCO Industries has supplied motor-compressors, electric motors, fans, blowers, and pumps for aerospace cooling systems for more than 50 years. Founded in 1976 and based in Le Poët, in the Hautes-Alpes, the family-owned business specializes in cooling solutions for severe environmental conditions, with a particular strength in compressors that balance power against weight. Its 1,000 square meter facility handles both custom engineering and small-to-medium series runs, and it holds ISO 9001 and EN 9100 certifications. WELCO's OEM relationships aren't named publicly, a choice that keeps its client list confidential but also keeps the company almost entirely absent from search results built around brand names rather than capability.

04Soterem

Founded
1975
Based in
Castanet-Tolosan, near Toulouse
Builds
Electro-mechanisms, electric motors and complex equipment
Credentials
Space, nuclear, aerospace and defense

Soterem has designed and manufactured electro-mechanisms, electric motors, and complex equipment since 1975, splitting its work roughly evenly across space, nuclear, and aerospace and defense, with the remainder in industry. Based in Castanet-Tolosan, near Toulouse, its capabilities include experimental devices, thermal-vacuum test tooling, and high-temperature furnaces, backed by a workforce that's about 40% engineers and managers and 60% qualified technicians. Public sources indicate its nuclear-sector work began with the French nuclear research authorities as its first client, before it expanded into aerospace and defense. Its website is a bare, unstyled affair with no content marketing behind it at all, a company doing space-grade engineering work that reads, online, like it barely exists.

05Servat

Founded
1990
Based in
Lieusaint
Builds
Custom motors from 10 W to 15 kW, generators and starters
Credentials
ISO 9001 · EN 9100 · PART 21G · PART 145

Servat manufactures custom electric motors from 10 watts to 15 kilowatts, in both DC and AC, brushed and brushless, along with generators, starters, and assemblies for major aerospace manufacturers, with additional work in rail and nuclear. Founded in 1990 and based in Lieusaint, it operates as a deliberately human-scaled organization, and holds ISO 9001, EN 9100, and PART 21G approvals alongside a PART 145 maintenance facility, letting it take on obsolescence management and lifespan-extension redesigns that keep older equipment running. Its digital footprint is limited to directory listings, exactly the kind of company this series exists to surface.

Founding years of the five manufacturers profiled above. None of that history is what a search engine ranks.

Five companies, one pattern: decades of qualified capacity built on referrals and OEM relationships rather than search rankings. Procureezy's manufacturer index exists precisely to close that gap, putting searchable, structured profiles behind companies that have never needed one before.
