[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor ... provide all that is needed to read the encoder, control the motor rotation and listen on the ‘stepper ...

That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC). [Fileark] built and ESC using an Arduino and has a couple of posts ...

This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor ...

The encoder delivers data for display or data that may serve as feedback in a motor-control system ... has two additional wires that supply dc to the encoder. It’s hardware-compatible with ...

or else breaking down and wiring up a Schmidt trigger on each encoder output. A stepper motor and driver was wired up to the Arduino UNO (Figs. 5 and 6). Now, in addition to the serial monitor ...

Full 4 quadrant control can be achieved with brushless motors using only hall sensors. A DC tacho or encoder can be optionally used with the DC motor for tighter feedback loops and digital inputs ...

The AC7 and DC7 motor controllers are meant for vehicle designers who demand more—from control accuracy to rugged reliability ...
