A new electromagnetic method for the nondestructive evaluation of electric pumps with ball bearings is proposed. A permanent m agnet generates a static magnetic field and a coil of several hundred turns wrapped around it is used to pick up eddy currents induced inside rotating ball bearings and impellers. First, a method that make use of the autocorrelation is applied to the si gnals of the ball bearings. A relation between the processed signals and the size of the defects in the bearings is obtained....
