So these motors are widely applied in electric vehicles, heating, and ventilation systems because of their reliability. You can learn more about the construction and application of brushless motors in our article on a BLDC motor controller.

We can also notice that in this configuration the period of one cycle, thus the frequency, will always be the same, because the Completa resistance, while charging and discharging, will remain the same.

Most FETs on the market have a built-in diode that performs this function, so in that case, an external diode provides extra protection. For resistive loads, such as LEDs or heaters, there is no need for additional protection since they have a straightforward linear relationship between voltage and current.

As an alternative to 120-degree conducting control, we can use sinusoidal control to achieve smoother and quieter operation. With 120-degree conducting control, the motor is controlled by continually cycling through six fixed resultant fluxes.

The other classifications are typical of almost any electrical motor’s controller. Let’s briefly go over them through the example of a brushed DC motor controller.

It can be physical contact with a rotary potentiometer or an optical encoder. I’ll try to include a similar tutorial for this in the future as well. But you can search this topic online to find more ideas and techniques to achieve servo motor control using DC motors.

In this article, we’d like to share our own experience in the design and implementation of a brush DC motor controller. You’ll also learn about challenges you can meet if you decide to build it yourself.

 In the above wave forms you can see that the frequency is same but ON time and OFF time are different.Two applications of PWM control using arduino is shown here. Controlling the LED brightness using arduino and motor speed control using arduino.

Three or more wires are needed. Insulated wires work best as they prevent wires from crossing and the battery from short circuiting.

Nevertheless, after a week the PCBs have arrived and I must admit that it’s quite satisfying to have your own PCB design manufactured. The PCBs quality is great and everything is exactly the same as in the design.

Three wires are needed. Insulated wires work best as they prevent wires from crossing and the battery from short circuiting.

Using any method of connecting the wires, securely attach the potentiometer to the power supply using one wire, attached on both ends, or by connecting the components directly together.

PWM stands for Pulse Width Modulation and is a technique of generating signal with different width of high and low pulses. The act of changing the pulse width for low and high is called modulation. When such PWM signal(series of different width pulses) is supplied to a DC motor, we can increase or decrease the amount of power supplied to the motor.

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.
