High Torque Compact Robot Joint Module
(1) Compact: 70mm diameter, built-in harmonic reducer, encoder and drive.
(2) Precise Control: high torque/weight ratio, easy speed control and precise positioning.
(3) Lightweight: 0.77kg, ultra-light weight, keep the robot as light as possible.
(4) Easy to use: can be connected directly with the robot.
This robotic joint module has a compact design with an outer diameter of just 70 mm, making it ideal for space-constrained applications.
The 18 mm central hole allows for easy cable routing, simplifying installation.
Weighing only 0.77 kg, it reduces the overall weight of the robot, enhancing dynamic response and operational efficiency.
The eRob70 motor meets high precision and low energy consumption requirements, making it widely applicable in industrial automation and precision operations.
8 Core Components for eRob Series Robot Joint Actuator
The eRob series robotic joint module is a highly integrated all-in-one solution that combines eight core components: a servo motor, high-precision harmonic gear reducer, dual absolute encoders, servo drive, friction brake, temperature sensor, and virtual torque sensor. This innovative design eliminates the need for complex external component selection and integration, providing users with a plug-and-play power unit that significantly simplifies the robotics development process. It is an ideal choice for building high-performance collaborative and humanoid robots.
