Vibration motor common faults and solutions
One: the vibration motor cannot start after the power is turned on.
the reason:
1. Stator winding phase-to-phase short circuit, stator winding open circuit, grounding
2, stator winding wiring error
3, the load is too heavy or the rotor is blocked
Approach:
1. Check for open circuit, short circuit grounding, and repair
2. Check the winding wiring and correct it
3. Reduce load and eliminate obstacles
Two: vibration motor temperature rise is too high or smoke
the reason:
1, the load is too heavy
2, winding short circuit
3, winding wiring error
4, winding ground or inter-turn short circuit
5, vibration motor rotor broken strip
6, fixed rotor phase rub
Approach:
1. Reduce the load or replace the vibration motor
2, repair the short circuit
3. Check the winding wiring and correct it
4, find the fault and repair
5, replace the rotor
6. Measure the air gap of the vibration motor, check the assembly and bearing wear, etc.
Three: bearing overheating
the reason:
1, bearing wear or quality problems
2, the bearing grease is too much or too little, the model is wrong or the quality is not good.
3. The inner ring of the bearing and the shaft are too loose or too tight.
4. The outer ring of the bearing and the end cover are too loose or too tight.
5, the assembly quality of the end cover and the bearing inner cover is not good.
Approach:
1, replace the bearing
2, adjust the grease
3. When it is too loose, it can be welded on the shaft to re-process the metal. If it is too tight, the bearing can be reworked.
4. When the steel is too loose, the end cap bearing chamber can be enlarged and then set, and the bearing chamber can be reworked when it is too tight.
5, remove and reload, so that bearing bearing capacity is even
Four: vibration motor housing is charged
the reason:
1, poor grounding
2, winding insulation damage
3, the winding is damp
4, the terminal board is damaged, or too much dust
Approach:
1. Identify the cause and fix it
2, repair insulation, and dry paint treatment
3, drying treatment or dipping paint drying
4, replace the wiring board, clean up the dirt
Five: bracket leg fracture
the reason:
1. The anchor bolts are not tightened
2, the installation plane is not flat enough
Approach:
1. Regular tightening bolts
2, re-processing the installation plane
