HPJM-RE50-60-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.
Features
1. Excellent Performance
Torque motor, with high overload capacity, for stable operation,
and more accurate and safe force control.
The double absolute value high precision multi circle encoder is
configured to ensure high output accuracy and repeated positioning
accuracy of 0.001°.
Multi turn double absolute value encoder + torque motor + high
rigidity harmonic reducer make virtual force control come true.
Large hollow shaft design, to meet the needs of central wiring,
while making the joint structure more compact.
2. Light weight
High efficiency: vector control algorithm based on model prediction
ensures high frequency motion control while maintaining low heat
impact.
3. Long life
The positioning accuracy is less than 0.015 ° and the repeated
positioning accuracy can reach 0.001 °.
4. Easy to install
6 different joint sizes are easy to integrate into the robot body
structure Compact 6 core elements of the robot joint are integrated
in limited space.
5. Sustainable
Lower power consumption, support many mainstream brand controller.
