Overview

Westmag designs and manufactures drone motors and robot actuators in the United States, starting with Factory 01 in South San Francisco. It automates winding, assembly, and testing on an integrated production platform to produce core motion components—the “muscle” of physical AI—for drones, humanoid robots, and other autonomous systems. The company differentiates itself by onshoring production and vertically integrating design, manufacturing, and the supply chain, including upstream subcomponents, to reduce dependence on foreign parts and improve cost control. Its goal is to scale production to hundreds of thousands to millions of motors and actuators annually for domestic and allied customers, while expanding a standardized product catalog for both high- and low-volume buyers.
