Westmag

Westmag designs and manufactures drone motors and robot actuators, building an integrated American motor company end-to-end. Based in South San Francisco, the company operates Factory 01 to produce BLDC motors for Group 1-3 UAS platforms and integrated actuators for humanoids and mobile robots, with automated winding, stator stamping, and in-house quality control under a domestic and allied supply chain.

Founded by David Hansen and Jordan Sanders, Westmag was built to address the critical supply-chain gap in US-manufactured motors and actuators for the autonomous-machine decade. The company serves defense and robotics customers with NDAA-compliant components, scaling from its semi-automated production line to millions of units annually while maintaining complete design, sourcing, and manufacturing control in-house.
