Sensor Mounting Stud Motor Fin Mount Predictive Maintenance Motor Vibration Monitoring vibration on induction motors forms part of the core of any predictive maintenance program Typical applications demand vibration measurements in the horizontal vertical and axial direction on both the inboard and outboard motor bearings Aside from typical mechanical issues such as misaligned couplings and unbalance the vibration analyst can also detect electrical issues that cause mechanical vibrations Some common electrical faults include air gap variation broken rotor bars and bearing fluting Vibration analysts can use one accelerometer mounted magnetically and rotate it around the motor to capture various data collection points In some cases the motor is in an inaccessible location and thus permanent mount sensors are used and routed to a junction box for walk up data collection Accelerometers are permanently mounted by drilling and tapping into the motor housing or they can be adhesively affixed or welded using a mounting pad Main Shaft Motor Fins Suggested Sensor Placement visit us online at www imi sensors com 1 716 684 0003 4
