Description
720 Brushed Motor Set
The 720 Brushed Motor Set is a compact propulsion component for small-scale RC aircraft, mini drones and DIY flying models. It features a 7 × 20mm coreless brushed DC motor paired with a 55mm propeller.
Coreless motors are designed with a lightweight rotor structure, making them useful in applications where low weight and quick motor response are important. The propeller converts the motor’s rotational movement into airflow and thrust, helping lightweight flying models lift and move.
This motor set can be used in suitable micro aircraft and small DIY propulsion projects. The correct battery voltage, propeller compatibility and motor arrangement are essential for safe and reliable operation.

How to Use / Setup
-
Secure the motor firmly in a suitable motor mount.
-
Carefully fit the compatible 55mm propeller onto the 1mm motor shaft.
-
Connect the motor to a suitable brushed DC motor driver or electronic switching circuit.
-
Use a compatible battery and verify the motor’s voltage rating before powering it.
-
Test motor rotation without the propeller first.
-
Once wiring and rotation are confirmed, install the propeller and test in a safe, open area.
For quadcopter projects: You need four suitable motors, a compatible motor controller, a flight controller, a battery and correctly matched clockwise (CW) and counterclockwise (CCW) propellers. Check the package contents carefully because this listing is for one motor set, not a complete four-motor drone kit.
Precautions
-
Do not exceed the motor’s rated operating voltage.
-
Avoid running the motor continuously under excessive load.
-
Never touch or obstruct a rotating propeller.
-
Keep fingers, wires and loose objects away from the propeller.
-
Do not operate a damaged or unbalanced propeller.
-
Allow the motor to cool after extended operation.
-
Confirm propeller direction and compatibility before flight testing.
-
Use a suitable driver circuit rather than connecting the motor directly to a microcontroller GPIO pin.
