Abstract
Description
Technical Field
[0001] This utility model relates to the field of geared motor technology, specifically a geared motor that outputs torque at both ends. Background Technology
[0002] Commercially available harmonic reduction joint motor modules all output force at one end, with a drive board and encoder installed at the other end. If the equipment requires output at both ends, two motors need to be installed and connected in parallel, doubling the cost and taking up more space.
[0003] Existing articulated motor modules do not offer a two-end output option; they only have a one-end output. If the application requires two-end outputs, two motors need to be installed and connected in parallel, doubling the cost, increasing space requirements, and making the control signals more complex.
