RC Brushless Motors vs Brushed Motors: What’s the difference?

When it comes to choosing RC electric motors, there are two main categories to choose from: brushed RC motors and brushless RC motors. 

Brushed RC motors use brushes to conduct electricity to the motor's spinning armature. This is an older design and is less efficient than brushless motors. However, they offer some unique features compared to basic brushless setups, such as smoother power delivery at low speed, making them ideal for crawlers. They are also typically more budget-friendly compared to their brushless counterparts. However, the brushes wear out over time, requiring regular replacement, potentially limiting their lifespan.

In comparison, brushless RC motors are designed and constructed so that they don’t rely on a mechanical contact to transmit power internally through the motor. This gives you less maintenance, less resistance and longer lifespans. These sleek performers deliver higher power efficiency and offer more precise control, giving you more power and more thrilling rides. However, they also tend to be more expensive than brushed motors.

FAQs about brushless RC motors

Do brushless RC car motors require different ESCs (Electronic Speed Controllers) than brushed motors?

Yes, brushless RC car motors do require different ESCs than brushed motors. The key difference between the two types of motors lies in how they are powered and controlled. Brushed motors use a constant DC voltage to charge the magnetic field that powers the motor, while brushless motors use electronic controllers (ESC) to regulate the flow of current to specific windings within the motor, creating a rotating magnetic field.

The ESC for a brushless motor is specifically designed to handle the unique electrical characteristics and timing requirements of brushless motors. It needs to be able to generate and control the three phases of electrical current necessary for the brushless motor's operation. Brushless ESCs often utilise more advanced features and programmable options like punch and timing to fine-tune the motor's performance.

Are brushless motors more expensive than brushed motors, and are they worth the investment?

Yes, brushless RC motors are generally more expensive than brushed motors. The higher cost of brushless motors is primarily due to their more complex design and higher manufacturing specifications. However, brushless motors have significant advantages over brushed motors when it comes to performance and longevity. 

Brushless motors are more efficient, have higher power-to-weight ratios and produce less heat and friction compared to brushed motors. They also typically last longer due to the absence of wearing parts and better thermal protection. The improved performance and durability of brushless motors make them a worthwhile investment for serious RC enthusiasts and those seeking top-notch performance from their RC vehicles.

How do I maintain my brushless RC motor?

Brushless motors generally require minimal maintenance compared to brushed motors. Since they lack physical brushes, there is no need to replace or adjust them periodically. However, some basic maintenance practices can help prolong the life and performance of your brushless motor.

Regularly inspect the motor for any signs of debris or dirt buildup, and clean it with compressed air or a soft brush if necessary. Ensure the motor's cooling fins are clean and free from obstructions to prevent overheating.

It’s also essential to keep the motor's bearings lubricated to reduce friction and wear. Use a high-quality bearing oil, and follow the manufacturer's recommendations for lubrication intervals.

What is an Electronic Speed Controller (ESC)?

An Electronic Speed Controller, commonly referred to as an ESC, is a crucial component in RC vehicles, especially those equipped with brushless motors. The ESC serves as the interface between the RC vehicle's receiver and the motor, regulating the flow of electrical current to control the motor's speed and direction.

For brushless motors, the ESC is vital in generating the electrical pulses that determine the timing and sequence of the current sent to the motor's windings. This precise timing ensures the smooth and efficient operation of the brushless motor.

Modern ESCs often come with programmable features, allowing users to adjust parameters such as throttle response, braking force and motor timing to customise the performance of their RC vehicles. The ESC's performance directly impacts the overall speed, acceleration, and control of the RC vehicle, making it critical for enthusiasts who want the best performance from their brushless motor setups.
