The larger High Efficiency Joint HEJ 90 targets locomotion and propulsion systems, generating up to 140Nm maximum torque, with customisation achieving up to 180Nm as required. This is combined with a maximum joint velocity of up to 13 rad/s. The HEJ 90 has an axial length of 90 mm, a diameter of 110mm, and a mass of 1.96 kg, operating with an input voltage between 30V and 60V.
The more compact High Efficiency Joint HEJ 70 achieves up to 50Nm maximum torque for mobile robot manipulation tasks, with a maximum joint velocity up to 28 rad/s. The axial length is just 73mm with 86.5mm diameter, and a mass of only 1.1kg, creating a powerful, lightweight solution. The HEJ 70 also operates with an input voltage between 30V and 60V.
