This case study highlights machinemonitor®'s approach in managing a critical anomaly in a high-capacity mill motor. The anomaly, characterized by abnormal current distortions, posed risks to equipment performance and personnel safety, necessitating immediate intervention.

Below we demonstrate how predictive maintenance can prevent catastrophic failures and align with safety and financial strategies.

Motors and generators are inherently reliable.

The operational stresses at the shaft, load, and connection to the power supply are factors that contribute to ageing and developing failure mechanisms.

Matching the machine to the application to understand the normal working stress and how this affects the machine components is the first step in effecting a reliability-centred maintenance program.

Electrical machines, with their concentric components, demand precise alignment.

Anomalies from construction, wear, and tear, or misalignment with driven equipment introduce eccentricities that can compromise efficiency and longevity. Proper training is essential for maintenance teams to appreciate these nuances and to qualify setups during maintenance checks.

Interventions become necessary when eccentricity occurs, emphasising the need for skilled personnel who can navigate these challenges effectively.

machinemonitor® today announced the launch of the 22nd annual Machines Conference, returning in partnership with Australian Energy Week, in Melbourne June 12 and 13 at the MCEC.

The conference is the key knowledge and networking event for Australasia’s electrical asset plant managers and maintenance engineers in the power & energy, manufacturing, oil & gas, mining, water utilities and large industries sectors.

“All our major industries – indeed our entire economy – runs on the back of very large rotating motors and generators, transformers, high voltage cabling and switchgear and data analytics systems, which require highly-specialised and trained professionals to maintain and run,” said Dr Jon Pemberton, machinemonitor® Director..
