The Solis Motor Hollow-Shaft Motor features a hollow-shaft architecture and highly integrated structural design, delivering high torque output and precise motion performance while providing a central passage for cables, pneumatic tubing, optical fibers, and transmission shafts. This design simplifies internal routing and improves overall system integration. With advantages including high torque density, fast dynamic response, high positioning accuracy, and a compact lightweight structure, the motor is ideal for applications such as humanoid robots, collaborative robots, medical equipment, semiconductor equipment, optoelectronic scanning systems, and precision automation equipment, providing customers with a high-performance and highly reliable motion solution.



The through-bore hollow shaft allows cables, pneumatic tubing, optical fibers, and signal lines to pass directly through the motor, reducing external wiring and improving system organization and reliability. The structure also supports integration with components such as slip rings and encoders.
Optimized electromagnetic design, magnetic circuit architecture, and thermal management enable higher continuous and peak torque output within a compact form factor, meeting the demands of high-load and highly dynamic applications.

A low-inertia rotor combined with a high-performance electromagnetic system enables rapid start/stop operation, high acceleration, and fast response, making the motor ideal for applications involving frequent motion cycles and high-speed dynamic operation.
Joint actuation for bipedal and full-body humanoid platforms
Safe, precise motion for robot arms and grippers
Power assist and rehabilitation exoskeleton systems
