Small size Hollow Robot Joint Motor Brushless Co-robot Joint Module
Product Description
This eRob series robot joint modules is a standardized joint module product based on our own servo drives and absolute encoders based on years of experience in serving customers, making robot development easier, faster, safer.
This eRob series robot joint modules include eRob70, eRob80, eRob90, eRob110, eRob142, etc., with exquisite design and compact structure. The compact size includes servo drivers, motor side absolute value encoder, output side absolute value encoder, and frameless torque motors, brakes, precision harmonic reducers and other main components, which save customers hundreds of mechanical and electronic components selection, design, procurement, assembly labor and time costs.
Product Features
Quick Build Robot robot joint motor brushless
Save the manpower and time cost of selecting, designing,
purchasing and assembling hundreds of mechanical and electronic devices.
Eight Core Components
Robot joint motor brushless
It integrates abosulte encoder, multi-turn absolute encoder at putput side, frameless torque motor, precision hamonic reducer, DC driver, temporature sensor, friction brake and torque sensor.
Small and Precise
robot joint motor brushless
The outer diameter is only 70mm, the OD of middle hole of which lines can pass through is 18mm. 0.98kg ultra thin light weight, reduce joing weight. Effective ensure a reasonable weight ratio of the robot.
