HPJM-RE50-70-PRO-XX Robot Joint Motor
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.
