A new electromagnetic method for the nondestructive evaluation of electric pumps with sliding bearings is proposed. A permanent magnet gen erates a static magnetic field and a coil of several hundred turns wrapped around it is used to pick up eddy currents induced inside rotat ing impellers. This electromagnetic nondestructive evaluation method is applied to the canned pump. By monitoring the movement of the impe ller in a canned pump, the rotation speed, the variance of the impeller position as well as th...

The epochal electromagnetic nondestructive detection method was proposed. In that method a permanent magnet is zed to generate static magnetic field and a several hundred turn coil is used to detect the eddy currents induced inside ball bea rings. In the present study the signal procedure method of a autocorrelation method is also proposed in tion to that detection method and these methods are applied to observe and evaluate ball bearings wounded by grinder. erimental validatio ns are carried out using a c...

This study evaluates the size of outer race defects of ball bearings during accelerated life testing by analyzing the signal of an electromagnetic sensor. The electromagnetic sensor consists of a pickup coil wrapped around a permanent magnet. When a conductor passes in the static magnetic field, the generated eddy currents are detected as a change of the magnetic field. The autocorrelation method is applied for sizing defects in the early phase of the damage growth and the RMS method is applied for la...
