Common Causes and Preventive Measures of Vibration Motor Burning (I)

 

Common Causes and Preventive Measures of Vibration Motor Burning (I)

1. The loosening of anchor bolts

Is one of the main failure cause vibration motor burned, due to the particularity of structure vibration motor itself, both ends of eccentric block vibration force to two thousand beats per minute to impact the anchor bolt, coupled with the vibration motor itself is concluded, pastly bolt is easy to loose, when a bolt looseness, in a relatively short period of time can cause other bolt looseness, even break, Burn the motor.

Preventive measures: 
(1)Often reinforce the anchor bolt.
(2)Increase anti-loose device. 
(3)Ensure good contact between the floor and the motor floor, so that several anchor bolts are evenly stressed.

2. Installation problems

Because both ends of the vibration motor are equipped with a heavier eccentric block, such as vertical or inclined installation (that is, the rotating shaft is vertical or inclined horizontal plane), the bearing axial to bear the gravity of the eccentric block. If there is no special device (plane bearing) in the vibration motor, it will have a bad effect on the bearing, so as to shorten the service life.

Preventive measures: 
(1)choose vertical vibration motor (that is, increase plane bearing inside).
(2) Try to avoid vertical or inclined installation.

3. The adjustment of eccentric block

When adjusting the eccentric block, the direction of the eccentric block at both ends is mistakenly adjusted to reverse, so that the vibration motor produces a space torque, so that the vibration motor works in an abnormal state, causing burning. Therefore, when adjusting the eccentric block, we must pay attention to its symmetry, that is, the two ends of the eccentric block should correspond to two, or the two ends of the center of gravity of the eccentric block should be parallel to the shaft, not into a different state.
