Product
Problem
Drone motors and robot actuators have been manufactured overseas for decades, creating supply chain vulnerabilities and quality control challenges for the growing autonomous-machine sector. As drone and robotics production scales to millions of units per year, US-based companies lack a domestic, vertically-integrated source for these critical components.
Solution
Westmag designs and manufactures drone motors and robot actuators through a vertically-integrated platform that covers design, sourcing, and manufacturing in South San Francisco. The company produces high-volume motor types for Group 1, 2, and 3 UAS platforms, as well as integrated actuators for humanoids and mobile robots. By building both motors and actuators on a shared architecture, Westmag creates a compounding advantage where every engineering investment and manufacturing process drives better performance and economies of scale. The company emphasizes automated winding, stator stamping, and coating to control quality and consistency, with products that are NDAA-compliant by default and sourced from US and Allied supply chains.
Target Audience
Primary customers are drone manufacturers building Group 1-3 UAS platforms and robotics companies developing humanoids and mobile robots that require integrated actuators.
Features
- High-volume production across a range of motor types for Group 1, 2, and 3 UAS platforms, with stator sizes from 20-100mm, prop sizes from 5"-50", and Kv ratings from 100-3,000
