The hum. The whirr. The steady beat of progress. Motors are the unsung heroes, the tireless workhorses powering our modern world. From the delicate whisper of a surgical robot’s arm to the thunderous roar of a wind turbine slicing through the air, they are everywhere. Yet, what happens when that hum falters? When the whirr becomes a grind? Catastrophic failure. Costly downtime. Missed deadlines. A silent symphony thrown disastrously out of tune.
