High end frameless torque motors used in robotics joints. Supplier cited by Morgan Stanley as a key motor source for humanoid actuators.
Kollmorgen is an American motion-control company specializing in servo motors, drives, automation systems, and precision motion technologies for industrial machinery, robotics, medical devices, and autonomous platforms. With decades of experience in high-performance motion systems, the company develops components that enable precise, efficient, and reliable control across demanding automation applications. In humanoid robotics, Kollmorgen is a key supplier of frameless servo motors designed for compact robotic joints and integrated actuator modules. Its motion-control technologies support high torque density, smooth operation, and accurate positioning, making them well suited for advanced humanoid robots requiring lightweight, embedded actuation.
By September 2025, Kollmorgen was publicly promoting its TBM2G motors for humanoid robots and appearing at the Humanoid Robot Forum. The company used that visibility to emphasize that its frameless motors were built for agile, efficient, and reliable humanoid movement.
Kollmorgen traces its history back to 1916 and is now tracked in Roboticos dataset as a major motion-control and frameless motor supplier. In the humanoid market, its relevance comes from supplying embedded actuation hardware rather than complete robots.
In April 2022, Kollmorgen introduced the TBM2G frameless servo motor series, highlighting tighter integration, lower joint weight, improved efficiency, and compatibility with standard strain-wave gearing. The launch positioned the company more explicitly toward robotics designers building compact and high-performance joints.
