We have explained PWM in this tutorial using 2 examples which will help you learn how to control LED brightness using PWM and how to control DC motor speed using PWM.
In this article, you will learn about the working principles and applications of this electronic device. We’ll tell you about the design nuances of a control unit used in one of the most popular electrical motor types – a brushed DC motor.
In other words, energizing of U, V, and W must be continually switched so that the resultant flux keeps moving, producing a rotating field that continually pulls on the rotor magnet.
The 555 Timer is capable of generating PWM signal when set up in an astable mode. In you are not familiar with the 555 Timer you can check my previous tutorial where I explained in details what’s inside and how the 555 Timer IC works.
Initialize the BUTTON & DC_MOTOR in the main application, start the DC Motor, read an analog potentiometer with ADC. And use that reading to control the motor speed in the main loop of the system. Read the buttons and use it to flip the direction of motor rotation. Repeat!
We opted for power MOSFETs that fit well with low voltage controllers because of the following advantages:

Is this sufficient? Perhaps it should come to complete stop a bit earlier, maybe at 5cm? Or perhaps, to be even more cautious, the vehicle should backup slightly away from the obstacle in order to provide room for a turns?
It is easy to build and offers adjustable speed and power settings. Previously we have also build many other types of DC motor speed and direction control steps you can also check them out from list below
In a BDC motor controller, the speed and torque are regulated by changing the power supply with the help of voltage regulators. They can be either a separate system or a part of the controller. For different purposes, engineers can use linear or switching regulators.
When the entire field is connected, the motor runs at the lowest speed. The speed can be further increased in steps by cutting out the resistance in the series turns. This method of speed control is used in electric traction.
The resistors can be any value but getting the exact speed needed from the motor requires testing with a certain range of resistors. The values of the resistors add up linearly so it is easy to calculate how to increase or decrease the motors speed by simply adding the values together. For example, two 1kΩ resistors wired together will act the same as a 2kΩ resistor.
The speed of a DC motor can be controlled by adjusting the voltage applied. This is because the speed and load torque of a DC motor is inversely proportional, and this translates with changes in drive voltage.
The circuit is connected in breadboard as per the DC motor speed control circuit diagram shown above. The pot here is used to adjust the speed of motor.
