High-reduction robot joints
The 102.08:1 metal gearbox, 6 mm D shaft, and integrated quadrature feedback support slower closed-loop joint mechanisms when load and thermal limits are validated.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.
