How Brushless Motor And ESC Work


How Brushless Motor And ESC Work

There are many things you should consider for understanding the working of ESC and brushless motor. It would help if you initially understood the working principle of the DC motor, which is brushless and electronic speed controller or ESC. After that, you should learn about brushless motor and ESC along with the working of BLDC motor through Arduino.

Working Principles Of Brushless Motor

A brushless or BLDC motor contains mainly two parts, the rotor, and the stator. Here, the rotor is nothing but a permanent magnet which has two poles. On the other hand, the stator is a coil which is arranged perfectly.

When the current is applied to the coil, it results in the generation of the magnetic field. Once it passes through the coil, magnetic field lines or magnetic poles depend completely on the direction of the current. So, when appropriate current is applied, the coil present inside generates the required magnetic field. This magnetic field results in attracting the permanent magnet of the rotor. Now, this results in can activating the coils one after the other and leads to rotation of the rotor. This works due to the force interaction, which is between the electromagnet and the permanent magnet.

Motor Efficiency

If you need to enhance the efficiency of the motor, you should wind two opposite coils and use them as a single coil. It results in generating opposite poles for rotor poles, and you can achieve a double attraction force.

By doing this, it is possible to generate six poles on stator just by using three coils. For further enhancements of the efficiency, you should energize the coils all at once. Through this, you can make one coil to attract the other, and the other will repel the rotor present. By achieving six intervals, you can easily result in 360 degrees cycle of the rotor.

What You Need To Know About Brushless Motor

In brushless ESC motor, as the permanent rotor magnets start rotating, the existing half-effect sensors sense the magnetic field. Through this, they generate login low for a pole, and for the other, they start generating logic low. Based on this, the ESC decides and understands when it should activate the upcoming communication interval.

There is one more method for understanding and determining the position of the rotor. It is by using the back electromotive force or by sensing backing EMF. Here, the back EMF exists because of the exact opposite process.
