P/N Interpretation
Product description
A robot joint motor is a motor used to drive the movement of a robotic joint, enabling a robot to perform specific tasks or motions. These motors are fundamental components in robotic systems, as they control the rotation or translation of joints, contributing to the robot's overall degrees of freedom
Key Components in Robot Joint Motors
Gearbox/Reducer Enhances torque output while reducing speed to match the robotic joint's requirements (e.g., harmonic drives, planetary gears).
Encoder Provides feedback on the motor's position or speed for precise control.
Controller Governs motor behavior based on input commands and feedback.
Brake (optional) Holds the joint in a fixed position when the motor isn't powered.
