T-Motor :- How to maintain a drone motor? How to know your drone motor needs to be replaced?

If you are an industrial drone user, you must develop the habit of maintaining the drone and its components. Drone motors a relatively sophisticated electronic mechanical devices and the key to maintaining the balance of the UAV, and the cost of a single motor will not be low, so maintaining and cleaning the UAV motor are very important.

Here are some practical tips for UAV operators, especially aiming for industrial uav motors, hope this helps you to solve some relevant problems. And meanwhile, if you think this article is useful, please give us a thumb, which would be very inspiring. 

How to maintain a drone motor?

1. Be sure the drone’s work environment is within the allowable temperature range.

Depending on the motor brand, there will be a different adaptation to the working temperature. Take the T-Motor motor as an example. The usual operating temperature of the motor is -20℃~65℃. Ensure your motor starts working at a suitable temperature.

2. Avoid water entering the motor and keep the interior dry

If the motor indicates that it is not a waterproof one, water ingress may cause bearing rust, accelerate bearing wear, and reduce the life of the brushless motor. In addition, there is also a possibility of rusting on parts like silicon steel sheets, shafts, and motor casings if there is water inside.

3. Regularly check the motor bearing

The inspection method of the motor bearing is to remove the propeller and drive the motor to see how it sounds. The normal rotation has no noise, and the sound is strong. If the sound is noisy, and there are noises as if sand is inside, the bearing might have been damaged and needs to be replaced.

4. Using a thick mat

It is recommended to use a thick mat on the ground when the drone takes off if the environment is dusty. Because of the strong wind during takeoff, some fine sand particles can be easily rolled up. Using thick mats on the ground during drone take-off can effectively prevent foreign objects from being drawn in by the wind hitting the motor.

5. Remember to check the motor for wear before each use

For example, sometimes there are small stones in it, which may cause the motor to get stuck after running. Before each use, you can blow it with air or buy a can of compressed air to spray it.

6. Check for normal operation

If a motor does not rotate or makes abnormal noise when powered on, it should be powered off immediately.

When these things happen to your drone, be aware of the health of your drone’s motors.

1. The external structure of the motor damaged

2. For most multi-rotor motors, if the axial movement clearance is greater than 0.5, please replace the motor. (Judgment method: measure the distance from the steel ring to the back cover)

3. Motor leakage occurs

4. The internal resistance of the motor is abnormal

5. The motor stops working completely/does not rotate

6. The motor shakes or freezes abnormally, slow in reacting

7. The winding is burned or broken, and there is abnormal noise.

Check the motor regularly
