The American
stator stack.

US-cut, bonded silicon-steel stator stacks — 32 to 100 mm — and the machinery that winds them. Built in Virginia.

1Why we
exist

The U.S. brushless motor supply chain runs through Suzhou, Milan, and Munich.

Every drone, every humanoid, every defense actuator on the Blue UAS list relies on stator stacks and the winding lines that fill them — almost none of it American. Vacuz dominates components and winding lines from China; Marsilli, Bosch, and GROB-WERKE compete on automated assembly from Europe. American Stator is building the alternative.

In build · 2026
Brushless motors are not optional components. The dependency is, today, unavoidable. The dependency is, tomorrow, our product roadmap.
3For

U.S. drone OEMs, robotics actuator companies, and defense primes.

If you build motion in America, your supply chain is our product roadmap.

  • 01 — Drone Group 1–3 UAS Blue UAS list operators sourcing onshore propulsion components and replacing 20-week China lead times.
  • 02 — Robotics Humanoid + actuator Quasi-direct-drive actuator builders onshoring stator stacks and outrunner shells in their bills of materials.
  • 03 — Defense Programs of record Loitering-munition, ground-actuator, and propulsion-system programs working a domestic-supply mandate.
