[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly ... mentions that this assembly has a weight and torque advantage over a NEMA 17 sized stepper ...
Building a 3D motor printed motor is one thing, but creating a completely custom servo motor with encoder ... Like other PCB motors it produces very little torque, roughly 2% of a typical NEMA17 ...
Servo drives are a cornerstone of modern machinery, enabling precise control of motion in industrial and automated systems.
