Why is Drone Propeller not Spinning?

When your drone propeller won’t spin, check the connections, motor, ESC, and flight controller. A loose connection could be the culprit, but so could a damaged propeller or dirty or damaged motor. Once you’ve diagnosed the problem, you can determine the appropriate solution.

Like any other mechanical device, drones are prone to malfunction, and one of the most common issues is when the propeller won’t spin. If you are facing such a problem, do not worry, as it can be fixed with the right knowledge and approach.

Here are the possible causes of a drone propeller not spinning and provide practical solutions to fix it.

Possible Causes For Propeller Not Spinning

Motor Malfunction: A faulty motor can cause a drone propeller not to spin. The motor may have burned out, become stuck or damaged in some way, or the motor’s wires could be disconnected.
Battery Issues: A low or dead battery may be another cause of a propeller not spinning. If the battery does not have enough power to run the motor, the propeller will not spin.
Wiring problems: Wiring issues can prevent the motor from receiving power, which in turn, will not spin the propeller.
Propeller damage: Damaged or bent propellers can cause the propeller not to spin. It is important to inspect the propellers regularly for any signs of wear and tear.
ESC failure: The Electronic Speed Controller (ESC) is responsible for regulating the power and speed to the motors. If the ESC fails, it can cause the motor to stop working.
Flight Controller malfunction: A malfunctioning flight controller can also cause a propeller not to spin. The flight controller is responsible for sending signals to the ESC and motors, and if it fails, the propeller will not spin.

Diagnosing The Problem

Now that you have identified the possible causes of a drone propeller not spinning let’s move on to diagnosing the problem.

Check the Motor: The first step is to check if the motor is functioning correctly. To do this, remove the propeller and turn on the drone. If the motor is functioning correctly, it should spin freely. If it does not, the motor may need to be replaced.
Check the Battery: If the motor is functioning correctly, the next step is to check the battery. Make sure the battery is charged, and the voltage is correct. If the battery is low, charge it, and try again. If the battery is damaged, replace it with a new one.
Check the Wiring: If the motor and battery are functioning correctly, the next step is to check the wiring. Inspect the wires and connections for any damage, and ensure they are securely connected. If there is any damage, replace the wires or connections.
Check the Propeller: If the wiring is not the problem, inspect the propeller for any damage or wear and tear. If the propeller is damaged, replace it with a new one.
Check the ESC: If none of the above steps have fixed the problem, the ESC may be the issue. Check the ESC by connecting the motor directly to it, bypassing the flight controller. If the motor spins, the ESC is functioning correctly. If not, replace the ESC.
Check the Flight Controller: Finally, if none of the above steps have worked, the flight controller may be the issue. Check if there are any error messages or warnings on the controller, and consult the manual for any troubleshooting steps. If the problem persists, replace the flight controller.

Tools And Materials Required

To fix a drone propeller that won’t spin, you will need a screwdriver, pliers, a cleaning brush, replacement motors, propellers and an ESC or flight controller (if necessary). Optional tools such as a multimeter, heat gun and soldering iron may also be useful for more advanced repairs.

Wire Cutters: Wire cutters are used to cut wires to the correct length, and strip the insulation from the ends to make connections.
Replacement Parts: Depending on the problem, you may need to replace some parts, such as the motor, battery, propellers, ESC, or flight controller.

Optional Tools For Advanced Repairs

Oscilloscope: An oscilloscope is a tool used to display and analyze electronic signals, which can be useful in diagnosing complex problems with the motor or wiring.
Heat Gun: A heat gun is used to melt and mold plastic components or to help seal wires and connections.
Third-Hand Tool: A third-hand tool is a device used to hold components in place while soldering, making it easier to create connections.

Common Materials Required

Electrical Tape: Electrical tape is used to insulate and protect exposed wires and connections.
Heat Shrink Tubing: Heat shrink tubing is a type of tubing that shrinks when heated, which can help protect and insulate wires and connections.
Wire Connectors: Wire connectors are used to join two or more wires together.
Propeller Set: If your drone propeller is damaged or worn out, you may need to replace it with a new set of propellers.
Battery: If the battery is low or damaged, you may need to replace it with a new one.

Having the necessary tools and materials is crucial to fix a drone propeller that won’t spin. It is important to ensure that you have the correct tools and materials for the specific problem you are facing, and always follow the manufacturer’s instructions and safety guidelines when working on your drone.
