The robot joint module used for in robotic arms.
1、Excellent Performance:Adopt cogging torque motor, 6 times overload capacity,stable operation, current and speed "0" fluctuation, more accurate and safe force control.
2、The double absolute value high precision multi circle encoder is configured to ensure high output accuracy and repeated positioning accuracy of 0.001 °.
3、Multi turn double absolute value encoder + cogging torque motor + high rigidity harmonic reducer make virtual force control come true.
4、Large hollow design, to meet the needs of central wiring, while making the joint structure more compact, smaller size.
5、Generality:48V DC power supply, lower power consumption, support many mainstream brand controller.
6、Light weight.
7、Long life.
8、Easy to install.
9、Small size.
