If, prostate based upon your vibration data, you suspect that a motor has an electrical defect, then you can perform a quick verification check using your vibration data collector.
Place your vibration data collector in a live mode or continuous measurement mode. Turn off the electric power to the motor. Any electrically induced vibration should cease almost immediately when the power is removed. This is a very good indication that an electrical defect is present in the motor.
