At a large coal mining site, DataMind AI<\/a>\u2122 was deployed to monitor multiple conveyor drive motors – critical components in the site\u2019s material handling process. Shortly after deployment, the system flagged early-stage deterioration in one of the motor bearings. While traditional monitoring tools recognized this as a generic bearing issue, DataMind AI<\/a>\u2122 identified the true root cause:<\/strong> electrical fluting – damage caused by current leakage through the bearing.<\/p> This insight proved critical. Without it, the team might have simply replaced the bearing, unknowingly leaving the electrical issue unresolved. That would have led to repeated premature failures, rising maintenance costs, and increased operational risk. Instead, by addressing the underlying cause, the site was able to prevent recurring damage, extend the lifespan of future bearings, and avoid unnecessary downtime.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t Motor flagged as alarm:<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t Operational Mode Isolation<\/strong> Fluting Root Cause Detection<\/strong> After alerting the site, the team proactively replaced the bearing and resolved a grounding issue believed to have caused the damage.<\/p>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Detection Through Sensor Fusion<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
DataMind AI<\/a>\u2122 applied Sensor Fusion – combining vibration, tachometer, and motor current data – to detect mechanical faults in a noisy and highly variable conveyor environment. By isolating consistent operating modes, the system filtered out operational noise caused by changing loads, ore size, or belt dynamics – greatly reducing false positives and ensuring that vibration increases reflected real mechanical issues.<\/p>
Envelope analysis removed high-frequency noise and revealed early-stage bearing degradation. While the standard spectrum showed general wear, envelope demodulation exposed distinct fluting patterns – a form of electrical discharge damage to the bearing surface, enabling accurate root cause diagnosis.<\/p><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
