About this product

DM-J10422P-2EC is an integrated planetary joint motor with 100 Nm rated torque and 400 Nm peak torque in the current manufacturer table. It has a printed 1:22 reduction ratio, a 110 mm outer diameter and an 89.9 mm body height, with two 17-bit encoders and CAN control. This 48 V hollow joint has a 12 mm central bore and supports CAN up to 5 Mbps. Its manual prints a rotor-side 200 rpm limit whose relationship to the output rating is unresolved.
