Overview
Westmag designs and manufactures drone motors and robot actuators in the United States, starting with Factory 01 in South San Francisco, and runs an integrated production platform that automatically winds, assembles, and tests these motion components. Its products are the power sources for aerial drones, humanoid robots, and other autonomous systems, providing the “muscle” for physical AI. The company differentiates itself by onshoring production and pursuing vertical integration across design, manufacturing, and the supply chain, including upstream work like steel stamping and magnet finishing to gain cost control and reduce foreign dependence. Westmag’s goal is to scale to high-volume production—serving hundreds of thousands to millions of motors and actuators annually for domestic and allied customers while expanding a standardized product catalog for lower-volume buyers and ensuring a reliable US-sourced supply.

What believers are saying
- Westmag’s November 7, 2026 site says Factory 01 is ramping production.
- The company targets millions of motors yearly, matching drone and humanoid robot demand.
- Open engineering, manufacturing, and sales roles show active commercialization, not a science project.
What critics are saying
- Westmag still lists only 12-14 roles, signaling a tiny team for scale ambitions.
- Factory 01 must prove yield and reliability before 2027 orders become defensible.
- If customers delay switching from Asian suppliers, Westmag burns cash without reaching volume.
What makes Western Magnetics unique
- Westmag vertically integrates design, winding, stamping, and testing in South San Francisco, 2026.
- Its NDAA-compliant, U.S.-and-allied sourcing targets defense buyers avoiding Chinese motor suppliers.
