This motor is an upgraded version of motor 23HS22-2804D-HG50-AR4. It has higher precision and can meet the higher requirements for precise control of the AR4 robotic arm.

Please note that it is impossible to directly replace the gearbox HG50 on the old motor with a new separate gearbox YGS50 by yourself.

Please note: the coupling in the gearbox is not locked tightly, please be sure to lock it tightly before use. And the locking torque is 9.8Nm.
