Abstract
Condition monitoring of equipment, machines, and parts with rotational or linear movement that constantly changes speed, starts and stops at different positions, that does not make complete rotations is done according to the invention by binning vibrational data according to position and thereafter performing a Fourier transformation for analysis. Among other things this avoids smearing in the frequency domain due to speed changes.
