Keya KY96BL04035-15 Joint Motor: Redefining Precision in Humanoid Robotics

The Evolution of Humanoid Motion: Why Joint Motors Matter

Humanoid robots performing delicate surgical tasks or industrial assembly require actuators that balance 26N·m instant torque with ±0.05° positioning accuracy. Keya’s KY96BL04035-15 permanent magnet synchronous motor (PMSM) delivers this duality, powering next-gen robots for healthcare, logistics, and collaborative manufacturing.
