Key points for maintaining brushed motors with drone blades

The key points for maintaining brushed motors with drone blades mainly include the following aspects:

First, daily inspection and maintenance

Motor appearance inspection

Before and after each flight, the appearance of the brushed motor should be inspected for any damage, cracks or deformation. Pay special attention to the wear of the brush part, as the brush is a component that is prone to wear in brushed motors.

Blade inspection

Check whether the blades have cracks, notches or deformations. The integrity of the rotor blades is crucial to the flight stability and safety of unmanned aerial vehicles.

Make sure the blades are firmly installed and not loose. Loose blades may fall off during flight, leading to serious consequences.

Second, cleaning and maintenance

Motor cleaning

Use a soft-bristled brush or a clean cloth to gently wipe the motor housing to remove dust and debris. Avoid using damp cloths or chemical cleaners to prevent damage to the internal parts of the motor.

Regularly clean the accumulated dust and carbon powder on the motor brush part to maintain good contact between the brush and the commutator.

Blade cleaning

Use a clean cloth or a special cleaning tool to wipe the surface of the blades to remove dust and stains. Avoid scratching the blades with hard objects to prevent damage to the surface of the blades.

Third, lubrication and adjustment

Motor lubrication

The bearing part in brushed motors needs to be lubricated regularly. Use an appropriate amount of lubricating oil or grease to ensure smooth operation of the bearings and reduce wear.

Blade balance adjustment

Use a propeller balancer to check the balance of the blades. Unbalanced blades can cause the unmanned aerial vehicle to vibrate during flight, affecting flight stability.

If imbalance of the blades is found, it can be corrected by adjusting the installation position of the blades or using counterweights and other methods.

Fourth, troubleshooting and handling

Motor fault troubleshooting

If any abnormal operation of the motor is found (such as abnormal noise, overheating, etc.), its use should be stopped immediately and it should be checked whether there are any damaged parts inside the motor.

Check the wear of the brushes and commutator. If the wear is severe, they should be replaced in time.

Troubleshooting of blade faults

If it is found that the blades shake or deform during flight, new blades should be replaced immediately.

Fifth, storage and preservation

Motor storage

Store the motor in a dry and well-ventilated place, avoiding moisture and high temperatures.

If the motor is not used for a long time, it should be powered on and run for a period of time regularly to prevent the internal parts of the motor from rusting or sticking together.

Blade storage

Store the blades in a dry and dark place, avoiding direct sunlight and high temperatures.

When storing, the blades should be placed flat or upright to avoid bending or deformation.

Sixth, Safety Precautions

Flight safety

Before the flight, it is necessary to ensure that both the motor and the blades are in good condition to avoid flight accidents caused by malfunctions.

Maintain security

During the maintenance process, it is necessary to ensure that both the motor and the blades are in a stationary state to avoid electric shock or mechanical injury.

In summary, the key points for maintaining brushed motors with drone blades cover multiple aspects such as daily inspection and maintenance, cleaning and upkeep, lubrication and adjustment, fault detection and handling, storage and preservation, as well as safety precautions. Regular maintenance and upkeep can extend the service life of brushed motors and blades, and enhance the flight stability and safety of unmanned aerial vehicles.
