VERTICAL ELECTRIC MOTORS
The best mounting location for the i-ALERT2 device will depend on which class of vertical motor is being monitored. For
vertical solid shaft motors with 2 rigid bearings, instrument the upper thrust bearing housing first since this is the primary
bearing absorbing thrust loads. The lower bearing can also be instrumented if desired.
For vertical hollow shaft (VHS) motors it is recommended to mount the i-ALERT2 device adjacent to the thrust bearing at
the top of the motor. Most VHS motors do not have lower bearings and therefore there is no need for a second monitor.
