Do Different Balancing Speeds Provide Different Imbalance Values?
Yes. To obtain more accurate results, it is necessary to support the part at the same or similar points as in its actual mounting position during balancing. Dynamic balancing is a form of force balancing that simulates the actual operating conditions. This ensures that the equilibrium of the part is maintained in the balancing machine, reflecting real working conditions.

Rigid rotors are defined as rotors that do not change shape as their rotation speed increases and do not operate at their resonance frequency. These rotors maintain their imbalance at low speeds, allowing for stable operation. Rigid rotors are typically used in systems that operate at lower speeds and under constant loads.

Flexible rotors are rotors that operate at speeds near their resonance frequency and may experience slight deformation at these speeds. The balance of flexible rotors can vary during operation, so they often need to be balanced at higher speeds, close to service speeds. For optimal performance, in-place balancing is commonly used for flexible rotors. For more details, visit our difference between dynamic and static balancing page.

A balancing machine is an industrial system that measures the imbalance of rotating parts. Due to factory environment noise, as well as the rotation of motors and belts attached to the workpiece, a precise reference signal is needed. The balancing speed of the workpiece is crucial for this signal differentiation and for ensuring accurate imbalance measurements. While older systems faced challenges, modern balancing machines have largely prevented phase shift issues.

The imbalance reduction ratio indicates the amount of imbalance reduction achieved during the balancing process. A good balancing system should reduce the detected imbalance by 90-95%. For example, if an initial imbalance of 50 grams is measured and corrected, the remaining imbalance should be 5 grams or less, providing a 90% imbalance reduction.

What is Imbalance Reduction Ratio?
Imbalance is a vector quantity related to the geometry and physical properties of the workpiece, and in rigid materials, it remains consistent across different speeds. In high-quality hard-bearing balancing machines, the imbalance value stays within the specified tolerance range, even when measured at varying speeds. Minor variations at different speeds are acceptable within the limits, indicating high precision.

Should the Workpiece Be Balanced at Operating Speed in Dynamic Balancing?
Since imbalance is a vector quantity requiring precise correction, the weight must be added at the exact location specified. If the correct amount of weight is added in a different location, residual imbalance and angular shift will occur. In this case, even if the proper correction amount is applied, the remaining imbalance and angle should be re-evaluated and adjusted accordingly. For more information, see our best method for imbalance correction page.

What Are the Units of Imbalance?
In such cases, balancing can be performed at half the accepted tolerance value. For example, if a part requires a 50 gmm tolerance, you can set it to a remaining imbalance of 25 gmm. Then, check the angle and residual imbalance without changing your reference point. This process ensures that the remaining imbalance on the part is within the tolerance range.

The term "zero balancing" is not used in balancing processes. Typically, the workpiece is balanced within a specific tolerance range. For example, a workpiece balanced below 20 milligram-meters will have a remaining imbalance between 0 and 20 mmg. This is practically considered “zero balanced,” and the remaining imbalance is set at a particular angle.

This situation indicates that the workpiece is properly balanced. When the imbalance value is low, angular shift or high angle may be observed. This typically means the balancing process was completed precisely, and the residual imbalance does not affect the workpiece's proper function.

In this case, the dynamic balancing machine compensates for both static and dynamic imbalances in the fan, whereas the static balancing fixture only detects static imbalance. A fan balanced on a dynamic balancing machine may show a heavy spot when tested on a static balancing fixture, due to the inability of static fixtures to measure dynamic imbalances. During operation, the fan is balanced and does not cause performance issues.
