What is brushless rc




















You may know that one is more powerful than the other. Or that one runs better than the other. But do you actually know the real differences between brushed and brushless motors?

The simple answer is that the former uses brushes and the latter does not. However, it is a little more complicated than that. An electromagnetic field is created when the winding of the motor receives a current supply.

The winding then pushes and repels against a permanent magnet to cause the shaft to turn. The energy is then transferred from one winding to another that ultimately causes the motor shaft to spin continuously. As mentioned earlier, brushed motors have brushes inside them. These brushes are typically made of copper, silver or graphite and are used to convert electricity into motion.

They make contact with a mechanical rotary switch called a commutator and deliver an electrical current. When the current is passed through the windings, a magnetic field is created, repelled and attracted, which consequently causes the armature, also known as a rotor, to rotate. One of the advantages of brushed motors is they are fairly simple and reliable. They provide a basic two-wire control. This makes it ideal for entry-level cars and new users.

Even with their simplistic control, this type of RC motor gives more power for tight, tactical driving. As the sensor tracks the rotor position, it sends out reference signals to the controller. The controller, in turn, activates the coils in a structured way — one phase after the other. Today, the brushless motor is far more common than the brushed motor. However, both can be found in a wide range of applications.

Brushed DC motors are still used frequently in household appliances and in automobiles. If you are new to the world of radio control, or are just out of touch with the new technology, you may not know the differences between conventional brushed and brushless motor systems.

I have written this guide to help other radio control enthusiasts understand the differences between the two. B rushless motors offer more power and higher efficiency than the equivalent brushed motor of the same size.

As the shaft turns, this pushing energy transfers from one set of windings to the next causing the motor shaft to rotate continuously. The differences between the two motor types are listed below, as well as the advantages and disadvantages.

With a brushed motor, the windings are fixed onto the central shaft inside the motor case and spin with the shaft when current is applied. Power is supplied to the motor windings by two brushes positive and negative that push against the commutator on the central shaft. The friction between the brushes and the commutator is the reason why this motor is not as efficient as a brushless motor.

So, lets look at the difference between brushless and brushed RC cars and see which one would make a better option for you. This give a brushless engine much more efficiency in comparison to a brushed motor. Brushed motors are commonly used in cheaper RC cars, mainly because they cost less to produce.

Brushless motors often use LiPo batteries, which need more care than a beginner is likely going to know how to give, and it can be a little overwhelming.
