On 2 pole motors, the twice line frequency vibration level will appear to modulate over time due to it's close relationship with 2 times rotational vibration. Problems in a motor such as a rub, loose parts, a bent shaft extension or elliptical bearing journals can cause vibration at 2 times rotational frequency.
2. Condition Monitoring System (CMS) Condition Monitoring System is a system to continuously or intermittently acquire data remotely from several sensors, such as vibration sensors, displacement sensors and temperature sensors which are attached to the target machinery, for early detection of component anomalies based on the acquired data.

How to Identify, Correct a Resonance Condition Alain Pellegrino, Laurentide Controls Ltd. ... If the vibration peaks at a certain speed and the phase shifts by 180 degrees, this indicates a natural frequency of the equipment or structure. The actual natural frequency is the frequency situated in the middle of the phase shift (90 degrees ...
Condition monitoring for low voltage motors ABB Ability™ Smart Sensor is a condition monitoring solution that makes predictive maintenance possible for low voltage motors. By monitoring and analyzing data on motor operating parameters, motor users can avoid unexpected downtime, optimize efficiency and improve safety.
Introduction While the National Manager for one of Australia's largest Condition Monitoring service providers, I initiated a strategic review of the Condition Monitoring marketplace in order to identify and assess the changes occurring within the industry, and the opportunities and threats that these changes represented to our organisation.
• Geared motors, compressors, vacuum pumps • Gearboxes, centrifuges, vibrating screens, cable cars • Spindles and machine tools Technical details • Continuous monitoring (24/7): Vibration and temperature • For machines with permanent and variable operating points • Suitable for flexible expansion and for condition monitoring beginners
Jul 02, 2004· Regularly checking the operating temperature of each critical motor will pay dividends. I t is no secret that heat kills electric motors. But it is easy to forget that exceeding the rated operating temperature by as little as 10 C (18 F) can shorten the life of a threephase induction motor by half.
Vibration Monitoring is one of the most useful Condition Monitoring techniques available to maintenance technicians as early identification of problems such as Imbalance, Bearing Faults, Misalignment and Gear Tooth Mesh problems are critical factors in ensuring and extending the working life of machinery.
vibration of the units were acceptable and to indicate if there was any evidence of unit deterioration. Vibration data was collected from key points on the Equipment using an Enpac 2500 data collector. This data was then downloaded to Emonitor Odyssey vibration software for analysis.
Sep 08, 2014· Applications include concreteconsolidation equipment like internal and external vibrators, shaker tables and vibrating screens, and vibrating bulksolidsprocessing equipment like bins, hoppers and conveyors. The company says this meter is not only easier to use, it's more accurate (within 10 VPMs) than any vibrating reed tachometer.
