What is the difference between brushed and brushless rc

Beyond selecting 'brushless' or just reading the description when browsing our web-store, the tell-tale sign of a car with a brushless motor are three or more wires running from the ESC to the motor as seen below. Whilst in a brushed motor there is typically a red positive and a black negative wire connected as seen in the photo above , brushless motors rely on the ESC to switch up the power signals sent down these three wires.

Turns often stated just as T refers to the number of times the internal wiring wraps around the armature. Lower turn motors have less torque but more RPM so '15T' motors are often fitted to beach buggies and other zippy models such as the Jumpshot below.

Kv numbers help explain the number of theoretical rotations you can expect from inputting 1 volt of power to an unloaded motor, aka RPM per volt. The higher the Kv number, the faster the motor can potentially spin. Enthusiasts will doubtless be jumping up and down shouting YES at this point, but lets look at the advantages and disadvantages to the technology:. If you like to drive an RC crawler such as the Traxxas Defender at controlled , low speeds a high-turn brushed RC setup is just fine.

They are also ideal for children looking for a an easily controllable, robust system. Alternatively if you want a high-speed , high-power model such as the Traxxas UDR where the ESC programming can be adjusted, a brushless setup will be best for you.

Thus it is not unusual to get a car that looks very similar to its cheaper brushed sibling but has the added bonus of being heavily upgraded throughout. Remember that to get the most out of a brushless car you will also likely end up buying more expensive , energy dense, high-burst-rate, lithium-chemistry batteries.

Hence, the coils are gradually triggered synchronously, one phase after the other, and the electronic drive is initiated by the sensors. Though brushless motor RC cars are more expensive than the brushed-motor RC cars yet you will be able to find an affordable RC car with a brushless-motor system.

Hope the above information has been helpful to you and I hope you will find it easy to buy an RC car with the right motor that will be suitable for you. Though there are three major features to be considered, when choosing your motor, the most important is the motor system while considering efficiency, maintenance and lifespan. The best 8 RC car makers with a bit of history. Can you take a RC car on a plane. Table of Contents. Sensorless Brushless Motor. In addition, there tends to be more electric and electromagnetic noise due to the shifts of the brushes, shafts, and commuters.

While heat loss is also higher and all this adds up to lower efficiency and higher losses in brushed motors. Finally, as briefly mentioned earlier, brushes will wear out over time and will require repairs and replacements. Although all these factors may be considered minor when looking at the bigger picture, a potential buyer should be aware before making a decision between Brushed motors vs Brushless motors. The main con of brushless motors is that they are definitely more expensive than their brushed equivalents.

Therefore, a potential buyer should consider all factors before making his decision to buy. The prices for brushless motors are high due to the components in the motor itself.

Without going into too much detail, it can be noted that a brushless motor uses an electronic speed controller ESC , thereby costing more to produce. However, one must keep in mind that a brushless motor provides more value for money because they require fewer repairs and replacements of parts. Another disadvantage of brushless motors is that they offer less speed control. This translates to difficulty in driving a brushless motor radio-controlled car over rougher terrains when compared to brushed motor radio-controlled cars.

That is to say, if you plan to do drive the car relatively slowly and only occasionally require speed bursts, a brushed motor RC car would be more than enough. These cars are also easier for beginners who want some power but at a lower price. However, if you want to be able to drive your radio controlled car faster than 15 mph and want to have better power efficiency, the brushless motor radio-controlled car is definitely better suited.

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. This means that it is easier for brushed RC cars to maneuver through rough terrains compared to RC cars with brushless motors because they have less or minor external components.

In addition to their simplistic control, brushed motors are also great for beginners because the prices of brushed motors are far more affordable when compared to brushless motors. This may be because they lack electronic elements, or for reasons that you can read about below. DC brushed motors are also highly configurable.
