Nowadays, rotating machinery uses rotors. In order to ensure the balance of the rotor, a dynamic balancing machine must be used. Only rotors and equipment that have been verified by a dynamic balancing machine can be put into use, allowing users to rest assured.

Uneven distribution of rotor mass is one of the most important factors causing rotor imbalance. In actual production and work processes, the main reasons for uneven distribution of rotor mass are as follows:
1. The manufacturing material or blank of the rotor. In mechanical engineering, we encounter many rotor imbalances caused by the material itself. For example, when casting a rotor, the density distribution of the raw material itself is uneven, and the cast blank has defects such as sand holes, pores, and looseness. In addition, the uneven distribution of welds and other defects may also cause rotor imbalance to some extent.
2. The rotor experiences imbalance during long-term operation. During high-speed rotation, the rotor may experience wear, deformation, and other phenomena. At the same time, temperature changes may cause rotor deformation during operation. In addition, centrifugal force during operation causes relative displacement between parts, which breaks the original equilibrium state. Over time, significant vibration will occur.
3. The problem of rotor processing and assembly leads to imbalance. During the processing and installation of rotors, there are errors in machining accuracy and installation, which can affect the quality distribution of the rotor around the axis and cause rotor imbalance.
4. The rotor is unbalanced during the maintenance process. During the maintenance process, normal technical repairs such as disassembly and replacement of components may also cause uneven distribution of rotor mass, and the impact on rotor balance cannot be determined, with varying degrees of severity. Therefore, in order to ensure the normal operation of the rotor, we must perform dynamic balancing treatment on the rotor after each maintenance.
In rotating machinery, the rotor is a very important component, so it is necessary to ensure that the mass distribution of the rotor is uniform, which requires the use of a dynamic balancing machine for verification. According to the GB/T6444-1995 standard, the cause of rotor imbalance is due to uneven distribution of rotor mass. The rotor generates centrifugal force during rotation, which mainly affects the bearings and causes mechanical vibration.
