Load Acting on Robot Arm Driven by Electric Motor

Click For Summary
SUMMARY

The discussion centers on the load acting on a robot arm driven by an electric motor and the implications of gear ratios. It is established that the gear ratio does not reduce the load on the motor when the arm is static; instead, the load remains directly proportional to the load acting on the joint. The gear system continues to influence the load dynamics, even when the arm is held in position. This clarification is crucial for understanding the mechanical behavior of robotic systems.

PREREQUISITES
  • Understanding of electric motor mechanics

Hello all
I have a doubt with the load concept acting on a beam. Consider a robot arm, actuated using Electric motor. When the arm is static and hold in position by the motor, Does the Gear ratio reduce the load acting on the motor due to the Gear ? Or when the arm is static, the Gear system disappears and the motor arm link act as a hinge joint and the load acting normal to the arm is directly proportional to the load acting on the joint ?

No the gearing doesn't "disappear".
