Application
The planetary EX series special reduction motors are designed for robot arm joints. They have dual encoders, high precision, high rigidity and low backlash characteristics, which can meet the precise control requirements of different load scenarios. This series of motors are widely used in industrial robots, collaborative robots, automated production lines, medical robot arms, logistics sorting systems and precision assembly equipment to ensure stable transmission and precise positioning under high-speed operation. Its compact structure, high torque density and long life design can effectively improve the dynamic response capability and durability of the robot arm. It is suitable for automated operation scenarios with high repeatability requirements, and helps intelligent manufacturing and flexible production

Rated torque test method:
When the ambient temperature is 24 degres Celsius(no other heat dissipation methods).the test is performed at the rated speed, the motor torque reacheds tmeperature balance under the condition of a temperature ris of 60 degree Celsius, and the long-term working point is the rated torque valuce of the motor.
