Glossary Balancing Technology

Electrical runout

Systematic error of eddy current sensors with runout or shaft vibration measurements, which may be caused by residual magnetism or electrical irregularities of the measured part.

End drive

In a balancing machine, a mechanical drive consisting of a motor, an optional gearbox and a drive shaft. The drive shaft will finally connect to one end of the rotor to be balanced.

Equivalent n-th modal unbalance

The smallest single unbalance which creates the same effect on the n-th flexural principal mode as the real unbalance distribution of a flexible rotor.
