Drones have become increasingly popular in recent years, with various applications ranging from aerial photography to delivery services. A key component that determines the performance of a drone is its motor. Drone motors come in different types, each with its own advantages and disadvantages. In this article, we will explore the different types of drone motors, their working principles, pros and cons, and how to choose the right motor for your drone.


Understanding Drone Motors

Drone motors are responsible for driving the propellers, which generate the lift and thrust required for flight. There are two main types of drone motors: brushed motors and brushless motors.

Brushed Motors

Brushed motors are the older and simpler type of motor, consisting of a central rotor and a surrounding stator. The rotor contains a permanent magnet, and the stator contains coils of wire. When an electric current flows through the coils, it creates a magnetic field that interacts with the rotor’s magnet, causing it to spin. This spinning motion drives the propellers and generates the lift and thrust needed for flight.

One of the advantages of brushed motors is their affordability. They are generally cheaper compared to brushless motors, making them a popular choice for entry-level drones or hobbyist projects. Brushed motors are also relatively simple and easy to replace, which can be advantageous for maintenance purposes.

However, brushed motors also have some disadvantages. They tend to be less efficient compared to brushless motors, resulting in shorter flight times. Brushed motors also generate more heat and noise during operation, which can affect the overall performance and experience of flying a drone.

Brushless Motors

Brushless motors, on the other hand, are more advanced and complex. They do not have physical brushes or commutators and instead use electronic controls to regulate the motor’s operation. Brushless motors typically have three coils of wire in the stator and multiple magnets on the rotor. The electronic controls precisely switch the current in the stator coils to create a rotating magnetic field that drives the rotor.

One of the main advantages of brushless motors is their efficiency. They are generally more efficient compared to brushed motors, resulting in longer flight times. Brushless motors also tend to be more powerful and provide smoother and quieter operations compared to brushed motors. They are commonly used in professional drones and high-end consumer drones where performance and reliability are crucial.

However, brushless motors also have some downsides. They are usually more expensive compared to brushed motors, making them less accessible for budget-conscious consumers or hobbyists. Brushless motors are also more complex and may require.

Pros and Cons of Different Drone Motor Types

Just like with any technological innovation, drone motors come with their own set of pros and cons. Let’s take a closer look at the advantages and disadvantages of both brushed and brushless motors.

Brushed Motors: Advantages and Disadvantages

One of the key advantages of brushed motors is their affordability. They are a cost-effective option, making them accessible to beginners or those on a budget. Brushed motors are also relatively simple in design, which makes them easy to replace and maintain. They can be a good option for DIY projects or entry-level drones.

However, brushed motors also have their downsides. They tend to be less efficient compared to brushless motors, which means shorter flight times. The brushes and commutators in brushed motors also wear out over time, which can result in reduced performance and lifespan. Brushed motors also generate more heat and noise during operation, which can be a drawback in terms of overall performance and user experience.

Brushless Motors: Advantages and Disadvantages

On the other hand, brushless motors offer several advantages. They are more efficient, resulting in longer flight times and improved performance. Brushless motors are also more powerful, providing better thrust and lift capabilities, making them ideal for professional drones or those with heavy payloads. Additionally, brushless motors operate more smoothly and quietly compared to brushed motors, which can enhance the overall flying experience.

However, brushless motors also come with some drawbacks. They are generally more expensive compared to brushed motors, making them less accessible to budget-conscious consumers or hobbyists. Brushless motors are also more complex in design and require electronic controls, which can make them harder to replace or maintain for DIY enthusiasts.

Choosing the Right Drone Motor

When selecting the right drone motor for your needs, you should take several factors into consideration.

Drone Size and Weight

The size and weight of your drone play a crucial role in determining the appropriate motor type. For smaller drones or those with lighter payloads, brushed motors may be a suitable choice due to their affordability and simplicity. However, for larger drones or those with heavier payloads, brushless motors may be more appropriate due to their higher power and efficiency.

Flight Time Requirements

If you require longer flight times, brushless motors may be the better option as they are generally more efficient compared to brushed motors. However, if the flight time is not a primary concern and you are on a budget, brushed motors may still be a viable choice.


Budget is an important factor to consider when choosing a drone motor. Compared to brushless motors, brushed motors are typically more affordable, making them a more budget-friendly option. However, it’s essential to weigh the cost against the performance and longevity of the motor to make an informed decision.

Skill Level

Your skill level and experience with drones should also be taken into account. If you are a beginner or new to drones, brushed motors may be a more straightforward option to start with due to their simplicity and ease of maintenance. Brushless motors may be a better fit for experienced drone users seeking higher performance and reliability.

Maintenance and Care for Drone Motors

Proper maintenance and care for your drone motors are essential to ensure their longevity and performance. Here are some tips for keeping your drone motors in optimal condition.

Cleaning and Lubrication

Regular cleaning and lubrication of your drone motors are crucial to prevent dirt and debris from affecting their performance. Use a soft brush or compressed air to clean the motors and apply a suitable lubricant to the bearings as per the manufacturer’s instructions.

It’s heartbreaking to see your beloved drone sitting idle, unable to take flight due to damaged motors. That’s why it’s crucial to regularly check for any signs of wear and tear to ensure your drone stays in top shape and ready for action.

Avoiding Overheating

Drone motors generate heat during operation, and the excessive heat can cause damage. Avoid prolonged flights or pushing your drone motors to their limits, as it can result in overheating. Allow your motors to cool down between flights and avoid using them for extended periods to prevent damage from heat buildup.

Calibrating Electronic Controls

For brushless motors, proper calibration of electronic controls is crucial for optimal performance. Follow the manufacturer’s instructions for calibrating the motor’s electronic speed controller (ESC) to ensure smooth operation and prevent damage due to misalignment.


Proper storage is essential to protect your drone motors from dust, moisture, and other environmental factors that can cause damage. Store your drone in a dry and cool place, away from direct sunlight, and cover the motors with protective caps to prevent dust accumulation.


In conclusion, choosing the right drone motor is a critical decision that can significantly impact your drone’s performance and longevity. Both brushed and brushless motors have their pros and cons, and considering factors such as drone size, flight time requirements, budget, and skill level can help you make an informed decision.

Proper maintenance and care, including regular cleaning, lubrication, damage checks, and proper storage, are essential to ensure your drone motors stay in optimal condition and perform at their best.

Investing in high-quality motors, regardless of whether you choose brushed or brushless, and following manufacturer guidelines for installation, calibration, and maintenance can greatly enhance your drone flying experience and keep your drone soaring through the skies for years to come.
