The humanoid robot industry has made rapid progress this year, accelerating from technological research and development to production capacity. As a “technology complex,” it relies on key components such as motors and reducers to support it — among which the motor is the “heart” of the robot, determining the precision of joint movements and the stability of motion, all depending on motor performance.(Disclaimer: This article analyzes the industry based on publicly available information and does not constitute investment advice. The market carries risks, and decisions should be made cautiously.)As robots gradually begin mass production, the demand for motors is bound to surge. Today, we will outline the Top 10 companies in the humanoid robot and motor sector based on their “profitability” (measured by the return on equity (ROE) in the 2025 mid-year report; the higher the ROE, the stronger the ability to generate profits with its own funds), with a clear logic that is easy to understand:
First, let’s clarify: What is ROE?
In simple terms, it is “how much money the company earns from its net assets.” For example, an ROE of 10% means that for every 100 yuan of net assets, the company earns 10 yuan; the higher the value, the stronger the profitability.

Summary of Highlights
Humanoid robots are now transitioning from “technology testing” to “mass production,” and as a core component, the demand for motors will continue to grow. These 10 companies either already have products for sampling and orders or have laid out technologies in advance, with profitability among the top in the sector. Future attention can be paid to their progress in robot mass production, but it is also important to note that industry competition may intensify, and company growth may not always remain stable.
