Application
The EX single-branch series planetary reduction module adopts a compact planetary gear structure with high torque density, low backlash (≤1 arc minute) and excellent impact resistance, and is suitable for precision transmission scenarios with limited space. It is widely used in industrial robot joints, collaborative robotic arms, 360° cameras, pod PTZs, and filming to achieve high-precision positioning and smooth power transmission. Its modular design supports rapid integration, adapts to servo/stepper motors, and significantly improves the dynamic response and energy efficiency of equipment, especially suitable for lightweight and high-load automation needs.
Product parameters
1. The standard motor does not support brakes, which can be customized if needed.
2. The standard motor does not support waterproofing, which can be customized to IP54 if needed.
3. The standard motor supports CAN BUS and RS485.

Rated torque test method:
When the ambient temperature is 24 degrees Celsius (no other heat dissipation methods), the test is performed at the rated speed. The motor torque reaches temperature balance under the condition of a temperature rise of 60 degrees Celsius, and the long-term working point is the rated torque value of the motor.
