9.4.3 Vibration
Circuit Principle Diagram
Circuit analysis:
Y511-U00 adopts the welding type vibration motor, working voltage 2.5V, current 70mA.
Direct motor is controlled by the power chip.
Fault analysis and treatment process:
1. First confirm the motor welding is good.
2. Separate to the motor power supply, to see whether the normal work of the motor.
3. To determine the motor body no problem, it may be the power chip weld or power supply chip
