HPJM-RE80-110-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.
An Integrated High Torque Robot Joint Module is a sophisticated
mechanical device designed to facilitate movement in robotic
systems. This module is characterized by its ability to generate
substantial torque while maintaining compact dimensions. It
integrates various components, including motors, gears, and
sensors, into a single unit, simplifying installation and reducing
the overall footprint of robotic systems.
The compact size includes servo drivers, motor side absolute value
encoder, output side absolute value encoder, and frameless torque
motors, brakes, precision harmonic reducers and other main
components, which save customers hundreds of mechanical and
electronic components selection, design, procurement, assembly
labor and time costs.
