While tumbling on the web for something totally different, I found this very interesting post on SERVOMOTORS, STEPPER MOTORS AND ACTUATORS FOR MOTION. Although, the illustrations are dated, I like very much the detailed, accurate and almost exhaustive description of magnetic actuators.

DC motors (Part 3)

Part 1, 2, 3 Now that we managed to get rid of (most of) the spike generated by the opening the supply line of the motor, let’s look at this plateau which happens just after the spike. From the pictures in the previous post, we have been able to observe that the voltage of this […]

DC motors (Part 2)

Part 1, 2, 3 Time for code ! Let’s write a few lines of trivial code in order to drive our controller (Check previous post). You probably heard about the analogWrite() function which is very convenient for generating PWM. Well, we will not use it ! Is it because it is too easy ? It […]

DC-motors (Part 1)

Part 1, 2, 3 DC-motors are every where in many form factors, many performances and configurations. The aim of this series of posts is not to cover all aspects of DC-motors as there are so many publications available, most of them being of excellent quality. Firstly, I will concentrate on the most common brushed DC-motors . Next […]
