In those mechanisms, a high-torque, low backlash gearbox might be just the thing, and a 3D printable split planetary harmonic drive for the popular NEMA 17 motors would be even better. Right up ...

Realizing that it’s essentially a cycloidal drive meshed with a planetary gear set, he got to work in CAD and, in seemingly no time, had a design to test. You can see the full results of his ...

The electric motor's speed is reduced from tens of thousands of RPM down to wheel speeds by two separate planetary gearsets on either end of the casing. This allows the motor and gearboxes to be ...
