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.

01

DRONES & ROBOTS

The revolution is here. Millions of units a year, scaling fast.

02

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.
