What are frameless motors used for?
Robotics and industrial automation. Frameless motors enable the most compact and powerful robotic joints, enhancing the dexterity, versatility and efficiency of surgical robots, humanoid robots, exoskeletons, industrial cobots and more.
Control actuator systems. Frameless motors deliver optimum torque and speed while fitting within an extremely confined installation envelope. And they operate with absolute reliability despite the shocks, vibration and temperatures encountered in flight.
Compact rotary actuators. Frameless motors support the most compact and powerful actuator designs, enabling the tightest possible motion integration whether driving the load directly or via a compact harmonic, planetary or cycloidal gearset.
Submersible vehicles and robots. To drive compact submersible propulsion systems, frameless motors can be sealed in an oil- or gas-filled pressure vessels for reliable protection against subsea pressures or hazardous liquids.
