Currently in progress: the overhaul of a 5.6 tonne ship's propulsion gearbox.

Work of this scale demands both the right machine capacity and exacting attention to tolerance, critical factors in restoring a component that plays such a central role in a vessel's propulsion system.

Another day, another OPTIME condition monitoring install underway by Sutton.

Adding sensors to an existing asset structure is seamless, and spinning up a brand new asset takes less than 30 seconds. Fast, simple, no fuss.

All sensors are already streaming data to the cloud in real time, and they've now entered their one-week learning phase, building a baseline across different loads and process conditions to fine-tune what "normal" looks like.

Exciting things ahead as the data starts rolling in.

How much sawdust should you store inside a servo motor?

Ideally, none.

This Yaskawa servo motor recently came into our workshop in need of some attention, with a significant build-up of sawdust contamination inside the motor. The contamination had entered through a broken power connector, allowing dust and debris to find their way into areas where they definitely shouldn't be.

Contamination is one of the most common causes of servo motor issues. Over time, dust and debris can affect bearings, cooling, feedback systems, and overall reliability, increasing the risk of unexpected failures and costly downtime.

Following a thorough inspection, cleaning, testing, and restoration, the motor was returned to a much healthier condition and ready to go back into service.

The project was also supported by our Octava diagnostic technology, helping alexander accurately assess the motor's condition and validate performance throughout the repair process.

When it comes to fan balancing, getting the vibration level down is only part of the job.

Recently, our Senior Reliability Engineer, Sutton, was carrying out fan balancing as part of a commissioning programme. But rather than simply checking the 1x vibration level and moving on, Tom took a much deeper approach.

Bearing temperatures were monitored throughout the process, full spectrum vibration readings were collected and verified against online monitoring systems and DCS data, and the fan was gradually ramped up to identify any resonance zones where operation should be avoided.

This level of attention to detail helps ensure equipment is not only balanced correctly, but is operating safely, reliably, and efficiently before being handed back to the customer.

It's this thorough approach that helps reduce risk, improve reliability, and build long-term trust with our customers, often leading to repeat work and ongoing partnerships.

Are breakdowns and unplanned repairs disrupting your production schedule?

Moving from reactive maintenance to a proactive approach can significantly reduce downtime, improve reliability, and help keep operations running smoothly.

That's why we've created our free Proactive Plant Guide.

Inside, you'll discover how combining Predictive Maintenance (PdM) with Strategic Motor Repair can help you:

- Identify failures before they happen
- Improve equipment reliability and availability
- Reduce costly downtime and emergency repairs
- Build a more proactive maintenance culture

Servo motors are at the heart of many modern automated processes, providing the precise control, positioning, and torque needed to keep production running efficiently.

What often gets overlooked, however, is the importance of maintaining and repairing them correctly.

Unlike a standard AC motor, a servo motor incorporates complex feedback devices such as encoders and resolvers, which work alongside the controller to deliver highly accurate performance. This means successful repairs require much more than mechanical expertise alone.

The programming, setup, testing, and calibration of these systems are all critical parts of the repair process. Without the correct software and specialist knowledge, a servo motor simply won't perform as intended.

That's why we continue to invest in advanced test facilities and diagnostic technology like Octava-Origin, ensuring our team can accurately assess, repair, and validate a wide range of servo motor makes and models.

When precision matters, so does the quality of the repair.

What if you could assess the complete health of a servo motor without taking it apart?

Thanks to advanced servo motor testing technology, it's now possible to gain a full picture of a motor's condition through a single automated test.

From alignment and vibration through to winding condition, magnetism, temperature, brake performance, and feedback systems, potential issues can be identified quickly and accurately without disassembly.
