Unbalance is derived from the terms "balance" and "weight." Balance is achieved when equal weights are placed on both sides of a scale. Similarly, the mass distribution in a rotor can be evaluated in relation to its rotating axis. Unbalance is defined as an imbalance of mass weight. As the rotational speed increases, centrifugal forces, vibrations, and noises become stronger and more disturbing. Balanssızlık.

Balanssızlık kavramı “denge”, “ağırlık” terimlerinden türemiştir. Bir terazinin her iki yanına eşit ağırlıklar konulduğunda bu terazide denge (balans) vardır. Benzer şekilde bir rotorda, dönen ekseniyle ilgili olarak kütle dağılımı da değerlendirilebilir. Kütle ağırlığının dengesizliği balanssızlık olarak tanımlanır. Rotasyon sırasında bu hız arttıkça giderek güçlenen ve rahatsız eden merkezkaç kuvvetlerine, titreşimler ve gürültülere neden olur.

Lifespan
Bearings, swingarms, frames, and foundations may wear out faster as a result of unbalanced vibrations. Products with unbalanced parts have a shorter lifespan in general.

Safety
Vibrations can cause the retention rate in screwed or terminal connections to decrease, likely to result in component loosening. Electrical switches are disrupted by vibration, and cables may break from their connections. Lack of balance can significantly reduce a machine's operating safety - a threat to both humans and machines.

Quality
It is impossible to handle an unstable electrical appliance precisely. The user will exert more effort and become tired faster. Machine tool vibrations have a significant impact on production results. When grinders or high-speed wood processing machines, spindles and equipment are not properly balanced, they will not function properly and will produce more scrap.

Competitive Capacity
Vibrations can seriously hamper a product's competitiveness because stable, low-noise operation is always considered when assessing quality. A loud car or a vibrating household appliance are two examples of products that cannot compete in the market.

A balance calibration eliminates the forces, disturbing vibrations, and noises that appear as a result of imbalance. Meanwhile, the mass distribution of a rotor is improved so that relatively smaller centrifugal forces impact the bearings. When balancing, the type of imbalance should also be considered.
Bu sırada bir rotorun kütle dağılımı, yataklarında daha küçük merkezkaç kuvvetleri etki edecek şekilde iyileştirilir. Balans ayarı yapılırken ayrıca balanssızlık türü de göz önünde bulundurulmalıdır.

Type of Balances
It is classified into several types based on the severity of the imbalance. It affects the position of the imbalanced plane, whereas the type of imbalances may impact the selected balance calibration tolerances as well as the structure and functionality of any rotor.
