High end frameless torque motors used in robotics joints. Supplier cited by Morgan Stanley as a key motor source for humanoid actuators.
Kollmorgen sits in the robot-joint supply chain rather than the robot-brand layer. Its importance comes from robot-ready frameless motors that can simplify actuator design for cobots, exoskeletons, and humanoids where torque density, thermal behavior, and packaging matter.
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 is a long-established motion-control company whose frameless motors, servo systems, and automation components are used in robotics and advanced industrial equipment. Within the humanoid context, the company is especially relevant for frameless servo motors designed to fit compact robotic joints and other embedded actuation systems.
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.
