How to Use the Residual Unbalance Tolerance Calculator:

Select the Machine Type for the Residual Unbalance Tolerance Calculation:

Choose the appropriate balance quality grade for your machine by selecting the radio button in the left column of the Residual Unbalance Tolerance Calculator.

Enter Rotor Parameters into the Residual Unbalance Tolerance Calculator:

Input the rotor rotation speed in RPM to calculate the residual unbalance tolerance.

Next, enter the rotor mass and choose the appropriate mass unit from the dropdown to ensure accurate residual unbalance tolerance results.

Select Units for Residual Unbalance Tolerance Calculation:

In the Residual Unbalance Tolerance Calculator, choose the desired tolerance units from the dropdown list to match your specific requirements.

Select the Number of Balancing Planes for Accurate Residual Unbalance Tolerance:

Choose whether the residual unbalance tolerance should be calculated for one or two balancing planes based on your rotor’s configuration.

Calculate the Residual Unbalance Tolerance:

Click the “Calculate” button to perform the residual unbalance tolerance calculation. The results, including permissible unbalance and eccentricity, will be displayed below the form.

Clear the Residual Unbalance Tolerance Calculator Form:

If you need to reset the input fields, simply click the “Clear” button to start a new calculation using the Residual Unbalance Tolerance Calculator.

Error Handling in the Residual Unbalance Tolerance Calculator:

If any required field is missing or contains invalid data, the Residual Unbalance Tolerance Calculator will display an error message indicating the issue.

The calculator ensures that all inputs are positive numbers and that valid units are selected to provide accurate residual unbalance tolerance calculations.
