There is several reasons for no vibration of vibration motor. I choose one sample for reference.
One of the customer send the feedback that the 1027 motor have no current and not vibrate.
1.We disassemble the motor and checked.
The upper shell casing inspection: no abnormal examination
check the appearance of rotor rotor, check the power --both qualified
Check the stator components: the red wire of the stator assembly and the power of the brush -- NG,
the red wire end of the handle position of the plate machine damage (P1)
2.We find that the fundamental reason of the motor without current is the red line end plate injury to the soft power by the performance examination and disassemble inspection.
