About this product

DM-J8006-2EC V1.1 is an integrated planetary joint motor with 8 Nm rated torque and 20 Nm peak torque in the current manufacturer table. It has a printed 6:1 reduction ratio, a 96 mm outer diameter and a 40 mm body height, with two 14-bit encoders and CAN control. This explicitly named V1.1 revision has a 1 Mbps CAN interface. The source prints both 190 rpm and 390 rpm at 24 V for no-load speed; that voltage conflict is unresolved.
