Electric motors are the heartbeat of modern industrial operations. From pumps to fans and conveyors, their reliability directly impacts production efficiency. However, unexpected motor failure can lead to costly downtime. The most effective way to prevent this is through continuous monitoring.
As a leading vibration sensor manufacturer, Kehao Automation understands that detecting early signs of mechanical wear is crucial for predictive maintenance. In this guide, we will explore how to use vibration sensors to ensure your electric motors run at peak performance.

Why Monitor Motor Vibration?
Every motor has a unique vibration signature. When faults begin to develop, this signature changes. By installing a vibration monitoring system, you can detect several common issues before they become catastrophic:
-
Bearing Failures: Over 50% of motor faults are related to bearings.
-
Unbalance: Caused by dirt buildup or broken components on the rotor.
-
Misalignment: When the motor shaft is not perfectly aligned with the load.
-
Looseness: Structural issues or loose mounting bolts.
Where to Install vibration sensors on Motors?
For the most accurate data, placement is everything. You should mount the vibration sensors as close to the bearing housing as possible.
-
Horizontal Placement: Best for detecting unbalance.
-
Vertical Placement: Effective for identifying structural looseness.
-
Axial Placement: Crucial for spotting thrust bearing issues and misalignment.
Choosing the Right Sensor: 4-20mA vs. IEPE
When selecting a sensor for your motor, consider your control system:
-
4-20mA Vibration Transmitters: Best for direct connection to PLCs or DCS systems for simple overall vibration monitoring.
-
IEPE Vibration Sensors: Ideal for high-frequency analysis and detailed diagnostic work where an external data collector is used.
Conclusion
Implementing a robust monitoring strategy not only extends the life of your equipment but also optimizes energy consumption. By choosing high-quality industrial instruments, you invest in the long-term stability of your plant.
