9 best brushless motors for rcs
Brushless motors are a crucial component in remote-controlled vehicles (RCs), such as cars, drones, airplanes, and boats. These motors offer several advantages over traditional brushed motors, making them popular in the RC hobbyist and racing communities. Here's what you need to know about brushless motors for RCs:
Brushless vs. Brushed Motors: Brushless motors differ from brushed motors in their internal construction.Brushed motors use brushes and a commutator for electrical connections, while brushless motors have a stationary coil and a rotating magnet attached to the motor's shaft.
Efficiency: One of the primary advantages of brushless motors is their efficiency. They generate less heat and friction, resulting in improved energy efficiency and longer runtime on a single battery charge compared to brushed motors.
Durability: Brushless motors have fewer moving parts, which means they experience less wear and tear over time. This leads to increased durability and a longer lifespan, reducing the need for maintenance and replacements.
Higher Power-to-Weight Ratio: Brushless motors provide a higher power-to-weight ratio, meaning they can deliver more power for a given size and weight. This is especially important in RC applications where weight and power are critical factors.
Smooth and Precise Control: Brushless motors offer smoother and more precise control of speed and acceleration. This makes them ideal for RC vehicles where fine-tuned control is essential for performance and handling.
Reduced Electromagnetic Interference: Brushless motors produce less electromagnetic interference (EMI) than brushed motors, which can interfere with the operation of other electronic components in an RC vehicle.
Multiple Configurations: Brushless motors are available in various configurations, such as inrunner and outrunner motors. Inrunner motors have the rotor inside the stator, while outrunner motors have the rotor outside the stator. The choice depends on the specific RC application and performance requirements.
Sensor vs. Sensorless: Brushless motors can be sensor or sensorless. Sensorless motors are simpler and cheaper but may lack the precise control of sensor-equipped motors. Sensors provide feedback to the motor controller, allowing for smoother and more accurate performance.
Electronic Speed Controller (ESC): Brushless motors require an electronic speed controller to regulate their speed and direction. The ESC manages the power supply to the motor and interprets the control signals from the RC transmitter.
Maintenance: Brushless motors generally require less maintenance than brushed motors. They do not have brushes that wear out, so there is no need for regular replacement or maintenance of the motor itself.
Popular in RC Racing: Due to their performance advantages, brushless motors are commonly used in RC racing applications, where speed, acceleration, and precision control are crucial.
Battery Compatibility: When using brushless motors, it's important to choose compatible batteries and ESCs to ensure optimal performance and longevity.
In summary, brushless motors are a vital component in the world of remote-controlled vehicles, offering increased efficiency, durability, and precise control compared to brushed motors. These motors have become a standard choice for serious RC hobbyists and competitive racers looking to maximize the performance of their vehicles.

- Note!!! A wrong tooth ratio can cause the motor to overheat. The motor temperature should be lower than 212℉ during the operation. Temperatures above 212℉ will weaken the magnet and may partly melt the coils and eventually damage the ESC (because of strong current)!!! To avoid potential risks such as ESC/motor damage or malfunction caused by overheat, start with a very small pinion first and check the ESC & motor temperatures regularly throughout the run. The only way to prevent overheating.
User questions & answers
| Question: | How does this compare to a reaktor 3300kv motor by helion |
| Answer: | The measurement drawing to the left of the product listing shows the shaft diameter is 3 mm. |
| Question: | Will this work for a pottery wheel |
| Answer: | Prop size depends on the voltage you put on the motor. A 9x7 will likely draw too much current on this motor, which has a maximum of 13 amps. A 20 amp ESC should do the job. The specs say it will take up to a 9x5 prop. |
| Question: | Would this work for drifting? i have a tamiya tt02-d |
| Answer: | Goolsky 2204 is 4 x 2.8 x 2.1 inches. A typical brushed 550 motor is 3.07 x 2.24 x 1.5 inches. |
| Question: | what battery cn i run it on |
| Answer: | 3 mm motor shaft diameter. See the photographs associated with the product listing. |
