An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver. The result is a sizeable and capable ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor ... motor driver’ interface pins hooked up to the motion controller upstream. The Arduino source for this ...

ECM's new servo motor delivers 18.8Nm of torque from just 0.57kg-achieving an exceptional torque-to-weight ratio in an ultra-compact footprint. ECM's ‘Eight Ball' integrates a PrintStator ...
