While brushless power systems have become the preferred choice for most RC car racing enthusiasts due to their high performance, brushed ESCs remain widely used in various RC cars, especially in RTR RC cars.
What is an RC Car Brushed ESC?
It is the central electronic component in an RC car's power system, connecting the battery, receiver, and brushed motor. On one hand, it receives the throttle control signal output from the receiver; on the other hand, it converts the battery current into an average voltage or current usable by the motor using pulse width modulation (PWM) or other methods, thereby controlling the vehicle's speed, forward/reverse movement, braking, and drag braking.
Unlike brushless ESCs, brushed RC car ESCs do not require Hall effect sensors or back EMF detection to determine rotor position and achieve electronic commutation. Because the carbon brushes and commutator inside the brushed motor have already completed mechanical commutation, the RC car brushed ESC only needs to adjust the supply voltage and current to control the motor's speed, direction, and braking.
How Does a Brushed RC Car ESC Work?
When you throttle with the remote control, the receiver converts the command into an electrical signal and sends it to the ESC. The ESC then uses PWM technology to supply power to the motor, thereby regulating the motor speed. When you operate the brake or reverse control, the ESC also adjusts the motor's operating state according to the corresponding command, achieving braking or reversing.
Which RC Cars Use Brushed ESCs?
Brushed ESCs are the first choice for entry-level RC car enthusiasts due to their simple structure, lower purchase cost, and ease of installation and debugging. They are mainly used in the following types of vehicles:
Crawlers: Crawlers are designed for low-speed driving on rocks, rough terrain, and other obstacles. These vehicles often use RC brushed ESCs because, for crawler enthusiasts, smooth throttle control and predictable power output are often more important than pursuing high speeds.
The TYROTE Rumble 80 brushed crawler ESC is designed for outdoor RC crawling enthusiasts. With an IP67 protection rating, it effectively handles environmental challenges such as mud, wet conditions, and brief immersion in water during outdoor driving. Users can fully enjoy the fun of outdoor driving.
Monster Trucks: Entry-level and recreational RC monster trucks often use brushed ESCs. These vehicles frequently need to navigate rough terrain, grass, rocks, and other obstacles, and are prone to getting stuck in mud or dense grass.
Brushed power systems provide excellent low-speed torque and predictable throttle response, making them easier to control. Furthermore, RC brushed ESCs have a simple design and are easy to maintain.
Touring Cars and Off-Road Vehicles: For beginners who want to experience the fun of everyday driving but don't want to invest in a more advanced brushless system, using an RC brushed ESC can reduce the overall cost of the vehicle.
Furthermore, RC brushed ESCs provide a smoother and easier-to-control power output, helping beginners gradually become familiar with throttle control and off-road driving skills.
Why Brushed ESCs Still Matter in the RC Market?
Lower Cost
Brushed ESCs generally have a lower overall cost than brushless ESCs. This cost difference is crucial for RC car beginners; the lower investment reduces their concerns about vehicle malfunctions.
Ease of Maintenance
Brushed motors and ESCs have fewer parts, making them easier to disassemble and replace. Beginners can also use them to learn about electronics and improve their ESC control.
High Durability
Compared to high-performance brushless ESCs, RC brushed ESCs are more resistant to shocks, dust, and humidity. This is essential for crawler and off-road RC models.
Diverse Applications
For low-speed driving and off-road use, brushed RC car ESCs are perfect for RC enthusiasts who want to quickly get started and enjoy the driving experience without complicated settings.
In short, brushed RC ESCs continue to play a vital role in the RC car market. For RC car dealers and retailers, offering both brushed and brushless ESCs helps build a more complete product line, reaching a wider customer base and achieving business growth.
