Controllers are classified into digital and analog versions. The main difference between a digital DC motor controller and its analog variant is that the former comprises microcontroller (MCU) based hardware and firmware.
When selecting a DC motor, you need to consider several characteristics that specify the electrical properties of the motor. This includes:
Note that: I’ve deleted the Automóvel-generated TIM2 initialization function and its parameter. Since our DC Motor library will handle that, we don’t need that function at all.
The lesser the diverter resistance, the more current will flow through the diverter, thereby the field current reduces and so the flux be produced. A decrease in flux will cause the motor speed to increase.
As you deal with a brushed DC motor, you might come across the problem of excessive electromagnetic interference.
As the name suggests, the purpose of the L293D motor driver is to drive DC motors. The L293D is a popular motor driver IC that has a built-in H-bridge circuit that can drive two DC motors simultaneously.
But BLDC motors are more difficult to drive than brushed motors. With a brushed motor, all you need to do is to connect the power source to the positive and negative leads from the motor.
Implementing a feedback control system, we faced a problem with the microcontroller that couldn’t process the encoder signal outputs.

Typical configuration: three coils with 120º spacing. Driven by controlling the phases and coil currents.
The average voltage depends on the duty cycle of the signal, or the amount of time the signal is ON versus the amount of time the signal is OFF in a single period of time.
If running at more than a 5 amps, I would beef up the diode with a power schottky diode in a 2-lead to-220 package such as a DSS25. Great circuit, I used a similar one to control my brushed RC car before I went to brushless.
The direction of the motor’s spin can be changed by swapping the wires connected on either terminal of the DC motor. Due to the vast variety of potentiometers, the range of speeds may not be optimal for a specific application and a different type may be needed to have more fine control over the motor or to achieve a lower range of speed.
How to do position control using a DC Motor? well, this sounds like willing to create a servo motor. Basically, you’ll need to have some sort of feedback to tell the controller where is the DC Motor’s shaft.
