Drone Motor Types Overview
Brushed Motors
Structure and Operation
Brushed motors have a simple design. Inside, there are carbon brushes and a commutator. These parts help switch the current. This makes a magnetic field that spins the motor. The brushes touch the commutator and cause friction. This friction makes the parts wear out over time. The motor does not last as long because of this. Many old drone models use brushed motors. They are cheap and easy to make.
Pros and Cons
Tip: Brushed motors are a good choice for beginners and hobbyists because they cost less.
Pros:
- They are easy to replace because of their simple build.
- They cost less than other drone motor types.
- You can control them with simple electronics.
Cons:
- They are not very efficient because of friction.
- They do not last long because the parts wear out.
- They make more heat and noise when running.
Common Uses
Brushed motors are in toy drones and starter models. They work well for small, light drones. These drones do not need to fly for long or carry much weight. If you want a drone for learning or simple flying, brushed motors are enough.
Brushless Motors
Structure and Operation
Brushless motors use newer technology. They do not have brushes or a commutator. Instead, an electronic speed controller switches the current. This happens in the stator coils. It makes a spinning magnetic field that turns the rotor. There is no touching inside, so there is less friction. This means less wear and longer life. Brushless motors are in most new drones. They give strong power and are very reliable.
Pros and Cons
Note: Brushless motors are popular because they work well and need little care.
Pros:
- They are very efficient and powerful for their weight.
- They last longer because there is little wear.
- They run quietly and do not get very hot.
- They do not need much maintenance.
Cons:
- They cost more than brushed motors.
- They need an electronic speed controller to work.
- The wiring and setup are more complicated.
Common Uses
Most drones for consumers and businesses use brushless motors. They are in drones for taking pictures, racing, and work jobs. Brands like DJI and Yuneec use brushless motors for steady flight and longer battery life. If you want a drone for serious use, brushless motors are best. Retek Motion has many brushless motors for different drone motor types and jobs.
Coreless Motors
Structure and Operation
Coreless motors do not have an iron core in the rotor. This makes them very light. The rotor spins fast because there is less resistance. They can speed up and slow down quickly. Coreless motors have a wire coil that floats in a magnetic field. This lets them change speed smoothly and fast.
Pros and Cons
Pros:
- They are very light, so they are good for small drones.
- They can speed up and react quickly.
- They have a simple design with fewer parts.
Cons:
- They are not as strong as brushless motors.
- They do not last as long as brushless types.
- They cannot carry heavy things or fly for a long time.
Common Uses
Coreless motors are in micro drones and small quadcopters. They are best for light drones that need to move fast and fly for a short time. Toy drones and some racing drones use coreless motors for speed and quick moves. If you need a motor for a small, fast drone, coreless motors are a good choice.
When picking between these drone motor types, think about your drone’s size, weight, and what you want it to do. Retek Motion can help you find the right motor, whether you want a simple brushed motor or a strong brushless one.
Inrunner vs Outrunner
Inrunner Features
Inrunner motors are used in many fast drones. The rotor spins inside the stator, which does not move. This design lets the motor spin very fast. Inrunner motors are slim and light. They do not have much torque, but they are very quick. These motors are good for drones that need to move fast and stay light.
Key features of inrunner motors:
- High RPM for fast spinning
- Slim and lightweight design
- Lower torque compared to outrunners
- Efficient cooling because of the closed case
Tip: If you want a racing drone or one that speeds up fast, inrunner motors help you go faster.
Outrunner Features
Outrunner motors look different from inrunners. The rotor is on the outside and spins around the stator. This design gives more torque at slow speeds. Outrunner motors are wider and heavier than inrunners. They give strong lifting power and smooth flying. These motors are best for drones that carry cameras or heavy things.
Main advantages of outrunner motors:
- High torque for lifting and stable flight
- Lower RPM but better control
- Wider and heavier build
- Quiet operation with less vibration
Note: Outrunner motors are good for camera drones and work drones. You get steady flying and enough power for heavy loads.
Application Differences
You should pick the motor type that fits your drone’s job. Inrunner motors are best for racing drones and small quadcopters. They give you speed and quick turns. Outrunner motors are best for camera drones, delivery drones, and work drones. They give you lifting power and smooth flying.
| Motor Type | Best For | Main Benefit | Example Use Case |
|---|---|---|---|

Choosing the Right Motor
Picking the right motor helps your drone work its best. You need to think about a few important things before you decide. This part will show you what to look for and help you find the right motor for your drone.
Key Factors
Thrust and Power
Your motor must make enough thrust to lift your drone and what it carries. Try to get a thrust-to-weight ratio of at least 2:1 for normal flying. Racing or heavy drones need a higher ratio. Always add up your drone’s weight, including the battery and gear. Then, multiply by your ratio to know how much thrust you need.
Drone Size and Weight
How big and heavy your drone is changes what motor you need. Big drones need bigger motors with more torque. Small drones do well with lighter motors. The stator volume and size of the motor affect how strong and quick it is.
Propeller Match
It is important to match your motor with the right propeller. The motor’s KV rating and size should fit the propeller’s size and pitch. A bigger propeller gives more lift but needs a motor with enough torque. Racing drones use small, high-pitch props for speed. Camera drones use bigger, low-pitch props for steady flying.
Efficiency
Motors that are efficient turn more electricity into flying power. Pick motors with high efficiency to fly longer. Good cooling and strong parts, like good bearings and windings, help your motor last longer.
Tip: Always make sure your motor’s voltage range matches your battery. This keeps your motor safe and helps it work well.
| Factor | Description |
|---|---|
| Motor Size and Stator Volume | Affects torque, power, and how fast the motor reacts. Bigger motors make more torque. |
| Thrust-to-Weight Ratio | The motor must make more thrust than the drone weighs. A 2:1 ratio is good for basic flying. |
| Propeller Compatibility | The motor’s size and KV rating must fit the propeller for good flying. |
| Battery Voltage | Motors are made for certain voltage ranges, which change RPM and power. |
| Efficiency | Efficient motors turn more electricity into power for flying. |
| Cooling Requirements | Motors need to get rid of heat to last longer and not break. |
Application Guide
Racing Drones
Racing drones need to be fast and react quickly. Pick light motors with high KV ratings (1800–2400KV) and a thrust-to-weight ratio of at least 3.5:1. Use small, high-pitch propellers for quick speed. Retek Motion has motors made for fast moves and top speed.
Camera Drones
Camera drones need to fly steadily and smoothly. Choose motors with lower KV ratings (380–900KV) and high torque. Use big propellers for steady lift. Try for a thrust-to-weight ratio over 2.5:1. Retek Motion can help you get motors that hold heavy cameras and keep your video steady.
Toy Drones
Toy drones need simple, light motors. A medium KV rating (900–1500KV) and a thrust-to-weight ratio near 2:1 are good. These motors are easy to swap and cost less, so they are great for new users.
Industrial Drones
Industrial drones carry heavy things or do special jobs. Pick big, low-KV motors with high torque and strong parts. Use large propellers and batteries with more voltage. Retek Motion has motors made to last and handle tough work.

Lubrication
Lubrication reduces friction and helps your motors spin freely. You should only use lubricants made for electric motors. Do not use oil or grease that attracts dust. Most brushless motors have sealed bearings and need little or no lubrication. Brushed and coreless motors may need a small drop of light machine oil on the bearings.
- Apply lubricant to the bearings if the motor design allows.
- Wipe away any extra oil to prevent dust from sticking.
- Do not let oil touch the coils or electronic parts.
If you hear squeaking or grinding, check the bearings. Lubricate them if needed. Always follow the motor manufacturer’s instructions for lubrication.
Note: Too much oil can cause more harm than good. Use only a tiny amount.
Troubleshooting
When your drone motor does not work right, you need to find the cause quickly. Use these steps to diagnose common problems:
- Re-calibrate the electronic speed controller (ESC). Follow the ESC manual for the correct process.
- Check the sensors, such as Hall or current sensors, for faults. Use the right tools to test them.
- Look for electromagnetic interference. Try flying in a different place or use shielding on the wires.
- Make sure your drone is not carrying too much weight. Check the propeller installation and remove extra load if needed.
- Plan your flights to avoid long, high-load operations. Give your motors time to cool down between flights.
- Check the heat sink and cooling fan. Make sure they work well and keep the motor cool.
- Use a multimeter to test the motor windings. Look for short circuits or broken wires.
Alert: If you notice strange noises, loss of power, or overheating, stop flying and inspect your motor right away. Early troubleshooting can prevent bigger problems and costly repairs.
Replacement Signs
It is important to know when to change your drone motor. This helps stop sudden problems and keeps your drone safe. All motors get old and wear out, even if you take good care of them. You should look for clear signs that show the motor needs to be changed, not just fixed.
Common signs your drone motor needs replacement:
