US Startup Builds Robot Motors to Break China Dependence

America is finally getting its own muscle back in the robotics race.

Westmag, a South San Francisco startup, just emerged from stealth mode with $11 million in funding to solve a problem most people never think about: nearly every motor that makes drones fly and robots move comes from China. Led by heavyweight investors like Andreessen Horowitz, Founders Fund, and Lux Capital, the company is building what founder David Hansen calls "the great American motor company."

The numbers tell the story of just how dependent we've become. The global drone motor market alone hit $2.4 billion in 2024 and is racing toward $5.7 billion by 2029. Robot actuators are on a similar path, expected to double to nearly $4 billion by 2030. Right now, American companies designing the next generation of drones and robots have to wait months for parts made overseas, often redesigning their products around whatever components happen to be available.

Westmag is tackling this with a smart manufacturing approach at their facility they call Factory 01. Instead of making completely different production lines for drone motors and robot actuators, they realized both use many of the same materials and processes. This shared platform lets them serve more customers while keeping costs competitive with foreign suppliers.

The timing couldn't be better. Washington has grown increasingly concerned about foreign-made drone technology, passing legislation like the American Security Drone Act that restricts federal purchases of foreign systems. The FCC is expected to ban new models of foreign-made drone components, creating urgent demand for domestic alternatives.

The Ripple Effect

This isn't just about one company making motors. Every American robotics startup, every drone manufacturer, and every defense contractor currently builds their technology on a foundation they don't control. When those motors come from halfway around the world, innovation slows to the pace of container ships.

By providing reliable, high-performance motors made in America, Westmag gives these companies freedom to experiment and iterate faster. Jordan Sanders, the company's co-founder, points out that Western drone and robot companies should benefit from "compounding advantages of reliable, cost effective domestic component supply."

The company is already ramping up production to fulfill committed orders for hundreds of thousands of units. They're partnering with suppliers in the US and allied countries like Japan, even investing in their own steel stamping and rare earth magnet finishing to control more of the supply chain.

Investor Erin Price-Wright sums up what's at stake: "Motors and actuators are the muscle of physical AI, and right now America's share of that muscle is essentially zero."

That's about to change, one motor at a time.
