What Is the “Diagnostic Service”?

This is a web service that utilizes Nabtesco Cloud Services to monitor the condition of CMFS equipment in real time using data collected by the devices.
By remotely monitoring equipment status without the need to visit the site and detecting signs of abnormalities early, the service streamlines maintenance inspections and enables preventive maintenance.

 

“What the Diagnostic Service Can Achieve”

🟦Optimize on-site management by utilizing data obtained from CMFS equipment
🟦Remote Monitoring: Check equipment status at any time via the web
🟦Early Detection of Abnormalities: Prevent problems before they occur with alerts based on threshold evaluations
🟦Streamlined Maintenance and Inspection: Perform planned, data-driven maintenance

 

This service, powered by the Nabtesco Cloud Service, allows you to view data collected from CMFS equipment online.
It centralizes everything from external load measurements using bolt strain sensors to cloud integration, enabling you to remotely monitor changes in equipment condition.
By continuously reviewing the data necessary for planning inspections and maintenance, it supports the implementation of optimal measures based on the equipment’s condition.

The yaw system of wind turbines is constantly subjected to complex loads in harsh environments.
Are you struggling to respond to sudden problems, such as replacing the yaw drive unit or performing emergency repairs on the ring gear?

The root cause of these failures lies in the fact that the loads are “invisible.”
Undetectable loads accumulate, and one day, they suddenly cause an unexpected failure.

Nabtesco’s CMFS (Condition Monitoring System with Failure Avoidance Function) solves this problem at its root.

✅ Continuous load monitoring: Advanced sensor technology visualizes invisible loads in real time
✅ Active load control: Automatically suppresses excessive loads to protect the yaw system

Move from “repairing after a failure” to “preventing failures before they occur.”
Why not achieve maximum uptime and optimize maintenance costs with data-driven “true predictive maintenance”?

Nabtesco provides robust support for the stable operation of your wind power projects.

The one-and-a-half-year demonstration test of the CMFS system on a 3MW-class wind turbine, conducted to evaluate its performance, has been successfully completed.
We would like to express our sincere gratitude to all those involved for their cooperation.
Moving forward, we will strive to expand sales by effectively utilizing the test results to fully meet our customers’ expectations.

 

 

 

 

During pitch rotation, repeated loads are applied as the system adapts to changing wind conditions; as wear and deterioration progress, this manifests as changes in operational characteristics or abnormal load conditions.
By capturing these changes as data, CMFS supports maintenance decision-making even before a failure becomes apparent.

Wind turbines adjust the angle of each of their three blades according to altitude and wind speed to maximize the use of wind energy and ensure the safety of the turbine itself.
