1. Non-Drive End Vertical Motor Bearing Point
M = Turning Speed
Nonsynchronous Peak

2. Non-Drive End Vertical Motor Bearing Point High Resolution (0 – 45,000rpm)
M = Turning Speed
Side Band Peaks around Turning
Speed and Harmonics spaced at
36rpm.

3. Non-Drive End Vertical Motor Bearing Point (125,000 – 160,000rpm)
Each of these peaks are spaced at
7200rpm from Rotor Bar Frequency
40x Turning Speed
Rotor Bar Frequency?

4. Non-Drive End Horizontal Motor Bearing Point
M = Turning Speed
Nonsynchronous Peak is at 0.09 in/sec

5. Non-Drive End Axial Motor Bearing Point
M = Turning Speed
Nonsynchronous Peak is at 0.01 in/sec

6. Non-Drive End Axial Motor Bearing Point High Resolution (0 – 45,000rpm)
M = Turning Speed
Side Band Peaks around Turning Speed and Harmonics spaced at 36rpm. Are these Pole Pass Frequency Side Bands?

7. Drive End Vertical Motor Bearing Point
Nonsynchronous Peaks are
7200rpm away from
40xTurning Speed peak
M = Turning Speed

8. Drive End Horizontal Motor Bearing Point
Nonsynchronous Peaks at 7200rpm
away from 40xTurning Speed peak
M = Turning Speed
