Vibration measurements are made on motor bearing housings. Amplitude is expressed as inches peak-to-peak. Vibration limits for standard and precision balance are for the motor only without any mounted accessory . The same limits can generally be met with motor-mounted blowers, PY, and AN tachometers. Motors with a BC tachometer or a motor-mounted brake will have peak-to-peak amplitudes of 2 times the value shown below. Where vertical mounting is required, it should be specified on the order. (For special run out , refer to GE.) Standard Vibration Limits Maximum NP Rated RPM Peak-to-Peak Amplitude (inches) 3000-4000 0.0010 1500-2999 0.0015 1000-1499 0.0020 0-999 0.0025
