[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body ...
Usually, when you want a servo motor, you simply buy one already made. But if you need something unusual, you can turn any DC motor into a custom servo you can control just like [Dejan] did.
Behind the standard open loop drive, stands several other types of drive products: brush DC servo drives, DC drives, SCR DC drives, stepper drives / motors, AC servo drives, and brushless DC servo ...
DC servomotors are DC motors that incorporate encoders and are used with controllers ... The inertia ratio, another specification important to sizing servo motor systems, is defined as the proportion ...
