How to solve the vibration problem of DC gear motor

Some users in the process of using the DC gear motor, will ignore the vibration phenomenon of the DC gear motor this condition, but do not know that this is the DC gear motor failure, which is also a criterion to identify the DC gear motor good or bad. So, how to solve the DC gear motor vibration problem?

1, suppress the rotor unevenness.

2, maintenance to within the allowable unevenness.

3、Improvement of excessive tightness of shaft and core.

4、The anisotropy of thermal expansion, design improvement.

5、Improvement of strength design or assembly.

6、Correction of the shaft strength design, change of the type of shaft coupling (recommended: Yishun reducer) and correction of the center of the straight coupling.

7、Prevention of deflection of bearing end face and shaft attachment section or locking nut.
