Diagnosis and repair of motor vibration and bearing wear: Hobbywing X13 Power System Kit practical tutorial
In many years of experience in maintaining FPV drones, motor vibration and bearing wear are the main factors leading to unstable flight. This tutorial will teach you how to solve it step by step.
Problem symptoms: Common symptoms of motor vibration and bearing wear
- Symptom 1: Abnormal vibrations suddenly occur during flight, causing the screen to shake.
- Symptom 2: The motor heats up severely and the battery life is significantly shortened.
- Symptom three: Flight stability is reduced and it is difficult to maintain a hover
- Symptom four: Black box logs show increased high frequency noise
root cause analysis
Motor vibration and bearing wear are usually caused by the following reasons:
| reason | illustrate | Detection method |
|---|---|---|
| Bearing wear | Long-term high-speed rotation causes the bearing clearance to increase | Turn the motor manually and listen for rustling sounds |
| The magnet falls off | The magnet glue inside the motor fails | Disassemble the motor and check whether the magnet is displaced |
| Axis bend | Collision causes motor shaft deformation | Use a dial indicator to measure the axis runout |
| Coil short circuit | Coil insulation damage due to overheating or water ingress | Multimeter measures coil resistance |
Step-by-step diagnostic process
Step One: Visual Inspection
- Disassemble the propeller and check whether there is any obvious damage to the appearance of the motor.
- Rotate the motor and feel if there is any lag or abnormal noise.
- Check whether the motor base screws are loose
Step Two: Vibration Test
- Using Betaflight’s black box log analysis tool
- View the FFT spectrogram to identify peaks at specific frequencies
- Compare the vibration levels of four motors to identify abnormal motors
Step Three: Electrical Testing
- Use a multimeter to measure the three-phase resistance of the motor (should be roughly equal)
- Check whether there is any weak soldering at the connection between the motor and ESC
- Test the current consumption of the motor at different throttles
