If you want your drone to be flawless in everything it can, then selecting appropriate drone motors is more than just a technical choice.
With the drone market forecasted to grow from USD 17.0 Billion in 2023 to USD 57.8 billion in 2028 (Source: MarketsandMarkets, 2023), the need for high-end motors has never been better.
Be it just to construct a multi-rotor machine that performs acrobatic exhibitions or integrate it with a camera for filming or an industrial need.
Picking the right motor for your drone will have a very big bearing on the drone’s performance, power efficiency as well as the time of operation in the air.
So, without further ado, let’s take a look at some of the most popular FPV drone motors that have hit the market in 2024.
1. How Does the Drone Motor Work in FPV?
FPV drones rely on brushless motors for their speed, power, and efficiency.
Here’s a simple look at how these motors work:
- Flight Controller and ESC: The flight controller acts like the brain of the drone, sending commands based on the pilot’s inputs.
- The Electronic Speed Controller (ESC): It takes commands and controls the amount of power sent from the battery to each motor, adjusting the drone’s speed and direction.
Brushless Motor Mechanics:
- Stator and Rotor: A brushless motor has a stationary part called the stator, which holds copper windings, and a rotating part called the rotor, which has magnets.
When electricity flows through the stator, it creates a magnetic field that spins the rotor, which turns the propellers and generates lift.
- Continuous Rotation: The ESC switches the electric current in the stator to keep the rotor spinning, giving the drone the thrust it needs to fly.
Why Brushless Motors? Brushless motors are durable, efficient, and perfect for FPV drones, as they allow smooth control and longer flight times compared to brushed ones, which are mostly found in smaller toy drones.
With the combination of the flight controller, ESC, and brushless motors, FPV drones achieve the precision and performance that makes them exciting to fly.
2. How to Choose a Drone Motor for FPV?
Take an insight into this section and learn how to choose a Drone Motor for FPV.
You will also know the impact of it on the speed and performance of your drone.
2.1 KV Rating
KV stands for “RPM per Volt”, meaning that if a motor has a 2300 KV rating, it will spin at 2300 RPMs for every volt applied.
But choosing the right KV rating is more than just picking a number—KV affects your drone’s speed, torque, current draw, and efficiency.
Here’s how KV impacts FPV performance and how to select the best one for your build.
2.1.1 How KV Affects Speed and Torque
This section will clarify how KV affects the speed and torque of your drone:
- High KV Motors: These motors spin faster, which means more speed and power.
They’re ideal for racing and high-speed maneuvers, as they maintain torque at higher RPMs, delivering quick, powerful thrust.
However, they also tend to draw more current, making them less efficient for longer flights.
- Low KV Motors: With a slower RPM, low KV motors provide more torque and are more efficient, drawing less current.
They’re well-suited for larger props and heavier quads, offering better control and longer flight times, which is ideal for freestyle or cinematic FPV.
2.1.2 How KV Impacts Efficiency
High KV motors require more current to produce the same torque as lower KV motors, which can lead to lower efficiency due to increased electrical losses from:
- Battery resistance
- ESC resistance
- Motor winding resistance
This means that high KV motors may cause the battery to drain faster, and at extreme current draws, they may even experience voltage sag, reducing the overall power output.
2.1.3 Choosing the Right KV for Your Build
When picking up the right KV for your build, first must determine the power, efficiency, and flight characteristics.
To pick the best KV rating:
- For Freestyle or Technical Flying: Look for lower KV motors that match the current output of your battery and offer good torque without draining power too quickly.
This will allow for smoother control and longer flight times.
- For Racing or High-Speed Flying: Opt for higher KV motors to maximize speed. Test sustained full-throttle performance, and ensure your battery can handle the current without severe voltage sag.
General Tips:
- Lower KV works better with larger props and heavier drones.
- Higher KV suits smaller, lighter builds focused on speed.
In summary, matching KV to your flying style and setup will give you the best balance of speed, control, and efficiency in your FPV drone.
2.2 Stator Size
The stator size in a drone motor affects how it performs in terms of power, responsiveness, and cooling.
Stator size is shown in a four-digit format, like 2207 or 2306; the first two digits represent the width of the stator, and the last two represent the height (both in millimeters).
Wider vs. Taller Stators
- Wider Stators (e.g., 2506): Wider motors have better cooling because of their larger surface area, making them ideal for long flights or heavier builds.
However, they respond a bit slower to throttle changes because of the extra mass.
- Taller Stators (e.g., 2207): Taller motors are quicker to respond, making them great for racing or freestyle where fast throttle response is key.
2.2.1 Choosing the Right Stator Size for Your Needs
For those who have been looking for smooth, long flights (like cinematic FPV), wider stators are the best option to keep the motor cool.
And for those who are seeking quick and responsive flying (like racing or freestyle), taller stators are better as they respond faster.
Popular Sizes:
- 2207: Great for balanced performance in freestyle and racing.
- 2306: Good all-around choice with extra cooling.
- 2506: Suitable for bigger propellers and heavy builds, often used in long-range drones.
In summary, choose the stator size based on your flying style to get the best balance of cooling and responsiveness for your FPV drone.
Do You Know?
The first modern drone was the de Havilland DH82B “Queen Bee”, which was introduced in 1935 by the British Royal Navy.
2.3 Efficiency
One thing that must be noted is that when choosing an FPV drone motor, efficiency is key.
Because it shows how much thrust the motor can produce for the power it uses, measured in grams per watt (g/W); higher efficiency means longer flight times and less battery drain.
It’s also pivotal to consider efficiency at mid-throttle, where you’ll be flying most of the time.
Some perform well at low power but become less efficient at higher speeds, which can quickly use up the battery.
Another factor is current draw—motors that need less current for the same thrust are better for battery life.
The ones that draw too much current can strain the battery, causing shorter flights.
The right propeller also helps with efficiency. Testing different propellers can help you find a setup that gives good thrust without using extra power.
In short, a motor with balanced efficiency and moderate current draw helps keep flights smooth and gives your battery a longer life.
