What is dynamic balance

The motors of all electrical appliances are a whole composed of a rotor and a stator. However, due to manufacturing reasons, it is impossible to make the mass distribution of the whole part very uniform. When the rotor rotates at a high speed, a dynamic unbalance state will be formed, causing the motor to shake and generate noise during operation. In order to avoid this phenomenon or eliminate this phenomenon that has already occurred, it is necessary to make the rotor correct the balance of each edge portion by adding or removing weight under dynamic conditions. This process of correction is what people often call dynamic balance.
Why is there an imbalance?
In fact, when the motor leaves the factory, it has already been dynamically balanced. However, a small part of the motor may not meet the standard accuracy or the balance machine data is accurate when it leaves the factory. As a result, if we use it for a long time, it will wear out and the rotor will be choked One layer, over time, becomes unbalanced.
Impact of rotor imbalance
If the rotor is not in balance when it is rotating, it can be felt when the motor is running. The main feeling is that the motor will vibrate. Although the phenomenon of motor vibration may also be caused by other factors, it is still recommended to encounter the motor. If the vibration is more obvious, check the dynamic balance first. This probability is relatively high. The other is that when the motor runs to a certain speed, it will generate vibration and noise. In short, it will not be very good for people with obsessive-compulsive disorder.
In addition to the user's ability to feel the vibration, the imbalance of the motor will also damage the product itself. Long-term use of the rotor imbalance is more serious, which will lead to a reduction in the service life of the rotor, then it will also have an impact on the life of the product itself, and a long time will cause product strain. In addition, when the imbalance is serious, the rotor may also suffer from uneven wear due to abnormal lateral swing. In short, the impact of the rotor imbalance on the product itself is more than worth it.
