Windings

What Windings does

Windings Inc. is a 100% employee-owned (ESOP) custom electromagnetic solutions manufacturer founded in 1965 and headquartered in New Ulm, Minnesota. The company designs and manufactures custom electric motors, generators, rotors, and stators engineered for mission-critical applications across seven verticals: aerospace, defense, oil & gas, energy, motorsports, medical, and robotics. Core technology includes the DuraCORE™ product line featuring GORE Magnet Wire from W.L. Gore & Associates, enabling operation at temperatures up to 260°C and pressures up to 30,000 psi — capabilities validated in field tests showing 10x longer operational life versus industry-standard polyimide wire motors. Additional technical differentiators include a dedicated Clean Space manufacturing environment (for aerospace/space FOD prevention), concurrent manufacturing methodology, ultra-high-speed motor capability up to 100,000 RPM, and 500+ years of combined engineering experience across the employee-owner base.

Windings operates an end-to-end business model spanning design analysis, electromagnetic simulation (SolidWorks, SPEED, Motorsolve, Maxwell), prototyping, and full-scale manufacturing — with US-based production at New Ulm, MN (140,000+ sq ft) supplemented by a West Coast facility in Moorpark, CA (acquired as McCully Corporation in November 2022) and a nearshore manufacturing hub in Tijuana, Mexico (60,000 sq ft facility as of 2025, acquired as Baja Border Maquila in 2024). Annual production capacity reaches 50,000+ pieces. Revenue is generated through custom project quoting (no public pricing) on multi-year contracts, alongside engineering services and Design for Manufacturing and Assembly (DFMA) optimization. The company maintains rigorous quality certifications including ISO 9001:2015/AS9100-D, ITAR registration, NADCAP welding accreditation, and J-STD-001 soldering certification. Its customer roster spans major OEMs and defense primes — Lockheed Martin, Raytheon Technologies, Northrop Grumman, Honeywell, Airbus, Halliburton, Baker Hughes, Weatherford, Stryker, BorgWarner, Moog, Parker, and Sierra Space among others — and the company offers customers the option to retain IP rights on custom designs, a differentiator versus typical contract manufacturers. Leadership includes President & CEO Heather Braimbridge and VP of Operations Rudy Stanglmaier; the ESOP structure (created 1998, fully employee-owned since 2008) is central to the company's operating identity.

Partnerships

Three partnerships are on record, tiered core.

• Baja Border Maquila (now Windings Mexico)coreOEM/ Whitelabel/ Licensing Partner · 1 January 2024Windings acquired Mexico-based Baja Border Maquila (BBM) in 2024, renaming it Windings Mexico. This nearshore manufacturing alliance supports high-volume production scaling up to 50,000 pieces per year while maintaining AS9100 Rev D and ITAR-compliant quality standards. In 2025, Windings Mexico moved into a new 60,000 square foot facility.
• McCully Corporation (now Windings Moorpark)coreOEM/ Whitelabel/ Licensing Partner · 30 November 2022Windings acquired McCully Corporation on November 30, 2022, renaming it Windings Moorpark. The acquisition expanded Windings' manufacturing capacity on the West Coast and enhanced electromagnetic solutions for high-tech electric motor applications, accelerating deliveries for customers in target industries.
• W.L. Gore & AssociatescoreTechnology or Integration · 1 January 2021Windings partnered with W.L. Gore & Associates to develop the DuraCORE™ product line of extreme-environment electric motors. The partnership utilizes GORE Magnet Wire — featuring revolutionary insulation with hydrolysis resistance, high-temperature tolerance (up to 260°C), and high-pressure capability (up to 30,000 psi) — to create motors significantly outperforming industry-standard polyimide wire motors. Field tests confirmed 10x longer operational life.
