The Motor Shaft function detects bearing flash-over that can damage motor bearings. The measurement requires a connection to the rotating shaft of the motor. For this measurement, brushes are included as accessories. Alternatively, you can use a stranded wire probe. Fluke recommends the VP410 10:1 Voltage Probe. See Figure Figure 35. - Page 77 If a bearing runs hot or is noisy and high shaft voltages are measured, bearing flash-over currents can be the primary source of excessive bearing wear. • Check other sources of bearing wear, such as, coupling misalignment or looseness.
