P/N Interpretation
Product description
A robot joint motor is a critical component that powers the movement of a robotic arm or similar systems. It’s typically a rotary actuator, and its key requirements depend on the application, such as precision, torque, speed, and reliability.
Since your rotary actuator already integrates a motor, gearbox, and encoder for high precision, it’s well-suited for robotic joint applications.
Robotic joints, which are sometimes known as axes, are the moveable parts of a robot that cause relative motion between adjacent links. These links refer to the rigid components that connect the joints to ensure their proper and straightforward operation.
