Humanoid robot field.

Frameless torque motors show unique advantages in humanoid robot joint drive. Due to its unique hollow and large aperture and magnetic circuit design, this motor can effectively reduce the volume, thus reducing the weight of the robot itself. This feature makes frameless torque motors particularly suitable for robot joints that require high precision and flexibility, improving the robot's motion efficiency and responsiveness. 

For example, Tesla's humanoid robot Optimus uses frameless torque motors as the core component of its rotary and linear actuators, which are distributed throughout its joints to ensure high performance and reliability when performing complex tasks. In addition, Textron's technology migration based on automotive EPS motors has stepped into the humanoid robotics track, supplying frameless torque motors exclusively, further advancing humanoid robotics technology.

Medical equipment field.

With its small size, light weight and high power, frameless torque motors show a wide range of application prospects in the medical field. First of all, this kind of motor is particularly suitable for embedding into narrow spaces, and at the same time, it has high reliability and long service life, which ensures the stability and safety of medical equipment in long-time use. In medical surgical robots, it can provide high-precision control to accomplish various difficult surgical operations. 

For example, Kollmorgen's TBM2G series of frameless torque motors, which have high torque density and up to 300% torque overload capacity, are suitable for driving the joints of surgical robots. In addition, in wearable exoskeleton robots, frameless torque motors are used to drive joint movements, which can effectively help patients with rehabilitation training or assisted mobility, significantly enhancing the wearer's athletic ability and strength.

Aerospace.

Frameless torque motors play an important role in aerospace, especially in key equipment such as satellite pointing mechanisms, drone propulsion and navigation systems. They are designed to withstand the harsh space environment, including extreme temperature variations (-150°C to +120°C), and use samarium cobalt magnets to prevent demagnetization and ensure long-term stability for on-orbit operation. 

For example, TQ RoboDrive's ILM series of frameless stator-rotor mounting kits, originally developed by the German Aerospace Center (DLR) for extreme environments, achieve excellent torque density, very low energy loss, and superior dynamic response due to their integrated design. In addition, frameless torque motors are widely used in aerospace equipment such as weapon stations, sensor gimbals, and targeting systems to provide high-precision, high-efficiency power support.

General Automation.

Frameless torque motors are widely used in the field of general automation. Its shell-less structure can be directly embedded inside the equipment, which not only simplifies the transmission chain, but also improves system rigidity and space utilization, making it ideal for scenarios such as rotary axes of high-precision machine tools, die-cutting machines, and screen-printing machinery, which can achieve micron-level positioning and high-efficiency processing. 

In the field of industrial automation, collaborative robots are an important component, and the frameless torque motor is the core component of their joint drive. It can be directly integrated with harmonic reducer, encoder and other components in the robotic arm to provide efficient and accurate power support for applications such as precision assembly, material handling and quality inspection. 

For example, the third-generation frameless torque motor introduced by BBK has been benchmarked to international standards in terms of size and performance, and has been successfully applied to collaborative robot joints and industrial automation production lines. According to the activity log sheet of BBK, the shipment of this series of motors has reached 14,000 units in 2024, which fully demonstrates its potential for large-scale application in industrial scenarios.
