A direct current (DC) motor is the oldest type of electrical motor that has gained widespread use in a variety of electronic devices and equipment. DC motors have different arrangements and operation peculiarities.
The robot could easily move in any direction, avoid obstacles, make stops, and move again immediately. We achieved this by using a pulse width modulation DC motor controller that regulated the speed and rotational direction of the motor.
We can order the PCB from JLCPCB which are the PCB fabrication service of EasyEDA, and also they are the sponsor of this video.
Since the output will be high when the capacitor is charging and is low when the capacitor is discharging, we get a difference in high output and low output times, and so the PWM.
OMDC-MD10P controllers are used with linear encoders for precise speed control in Omega's manufacturing process for metal sheath thermocouple wire.
There are different types of speed control of dc motor. Let us discuss, how the speed can be controlled with the above parameters.
The speed of rotation can be controlled by controlling the rate at which the phases change. We use the name “120-degree conducting control” to the seis-mode control method described here.
Open-loop and closed-loop systems are fundamental concepts of control theory. Depending on the requirements or complexity of the electronic device, you can implement a control system either with or without feedback.

A 10k Ohm potentiometer is used here. The ends of the resistive track are connected to 5V and ground, respectively, and the wiper pin is connected to the A0 analog input pin of the Arduino UNO.
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.
More precise sensors—such as resolvers and optical encoders—are more appropriate with motors that use vector control (see below), where flux is more finely controlled.
BLDC motors cannot by definition use brushes or other mechanical contact to achieve this reversal. Instead, they generally use inverter circuitry to implement this control.
