Westmag designs and manufactures drone motors and robot actuators — built and scaled in America to serve the global market.
Onshore the motor.
Every drone has four motors. Every robot has tens of actuators. Westmag designs and manufactures both — in South San Francisco, with a domestic + allied supply chain, for the autonomous-machine decade.

DRONES & ROBOTS
The revolution is here. Millions of units a year, scaling fast.
MOTORS & ACTUATORS
At the core of every drone and every robot. Made overseas for decades.
WESTMAG
Building the integrated American motor company. End-to-end. Here.
Factory 01 - South San Francisco
Currently ramping production and testing. Anchored in South San Francisco to be close to our customers and talent. Automation and rapid iteration on motor design and manufacturing are core to our execution.
Vertically-Integrated Platform
A drone motor is at the heart of every robot actuator — that’s why we’re building both. This shared architecture is a compounding advantage. Every engineering investment, manufacturing process, and supply chain relationship drives better performance and economies of scale for customers.

DRoNE MoTORS
High-volume production across a range of motor types for Group 1, 2, and 3 UAS platforms.

ROBoT ACTUATORS
Manufacturing integrated actuators for humanoids and mobile robots.
Designed, sourced, and built in-house.
DESIGN
We characterize motors across the full performance envelope. Every design choice is made for manufacturing at scale.
MANUFACTURING
Built in South San Francisco. Automated winding, stator stamping and coating — we control quality and consistency.
SUPPLY CHAIN
NDAA-compliant by default. Focused on US and Allied sourcing for quality and resilience.
