1 loosening of anchor bolts

　　This is one of the main faults causing the vibration motor to burn out. Due to the special structure of the vibration motor itself, the exciting force generated by the eccentric block at both ends has to impact the anchor bolt thousands of times per minute, and then the vibration motor itself Vibration, so the ground bolt is very easy to loose. Once a bolt is loose, it will cause other bolts to loose or even break in a short period of time, thus burning the motor.

　　Precautions: 1) Reinforce the anchor bolts frequently 2) Increase the anti-loose device
