Application
Joint motors for humanoid robots are highly integrated power modules. They are not merely “motors” in the traditional sense, but rather complex systems that integrate motors, gearboxes, encoders, and drivers into a single unit. They directly determine the robot’s flexibility, precision, and load-bearing capacity, and represent a core component of the current industrial chain.
