Hope this article has helped you to better understand how to incorporate DC motors into your electronics projects! Leave a comment below if you have any questions.

Fine tune the motors speed. Now that the motor runs, achieving the desired speed is a matter of adding or changing the resistors. To decrease the speed, detach one end of the connected resistor and connect another resistor to that end of the resistor and reattach the disconnected side to the unconnected end of the new resistor.

Connect the resistor to one terminal of the DC motor. Attach the wire to the unconnected side of the resistor. This is best done using a wire instead of directly so that the resistor(s) are out of the way of the motor application.

Hey I'm Dejan, a maker, a techie and a mechatronics engineer. I love making electronics and robotics projects for you to learn and make something cool on your own.

So I’ve decided to use that function instead to keep the code more generic across all STM32 microcontrollers. Without having to figure out a way to find out which pin belongs to which timer’s channel and all that stuff.

This page will show step by step the relationship between speed, torque and drive voltage of a DC motor, and how to control it.

Also the transistor acts as a switch. When the output from the Arduino pin 10 is LOW then there is no base current, the transistor is driven into cutoff region of operation and therefore there is pelo collector current. In this case there is no current flowing through the DC motor.

With a discrete circuit, it will take you the time and effort to assemble and solder the components. The design of an integrated circuit, however, is quite expensive, and it can earn its keep only in case of mass production. 

The flux can be varied by varying the current Ish through the shunt field winding. It is done by connecting a rheostat in series with the field winding as shown below.

So as shown in above figure, for clockwise rotation 2A should be high and 1A should be low. Similarly for anti clockwise 1A should be high and 2A should be low.  

Using any method of connecting the wires, securely attach the resistor to the power supply using one wire, attached on both ends, or by connecting the components directly together. The amount of resistors here may vary depending on what speed the motor must run at.

By decreasing the flux produced by the field winding, the speed can be increased and vice versa. Hence the name flux control method or field control method.

You basically right-click the project name in the IDE’s navigator and choose to create a new > source folder. And name it ECUAL and go to the GitHub repo, download the files and copy the “DC_MOTOR” folder and back to the IDE, right-click on the ECUAL and paste the library into it.

A variable resistance(Rheostat) called field diverter is connected across the series field winding. A portion of the current flowing through the series field winding is diverted into the field diverter by varying its resistance.
