What are the differences between dynamic balance and static balance?

[EdenLynn]

Dynamic balance and static balance differ as follows: 1. Different in nature: Static balance is corrected on a single correction plane of the rotor, with the remaining unbalance after correction ensuring that the rotor remains within the allowable unbalance range when static, hence it is also known as single-plane balance. Dynamic balance is corrected simultaneously on two correction planes of the rotor, with the remaining unbalance after correction ensuring that the rotor remains within the allowable unbalance range during operation, hence it is also known as two-plane balance. 2. Different focus: In static balance, the center of gravity of the wheel aligns with the axis of rotation, allowing it to stop at any position. If a wheel consistently stops at the same position each time, it indicates static imbalance. Dynamic balance is a phenomenon observed during the rotation of the wheel. Due to the asymmetry of mass relative to the wheel's symmetrical plane, when the wheel rotates at high speed, it swings from side to side, which is the phenomenon of dynamic imbalance.
