Most maintenance managers understand motor repair and rewinding. But when core iron testing reveals excessive losses in the stator laminations, you face a more complex decision: motor restacking. This advanced rebuild can save tens of thousands of dollars on large motors—but only when the economics make sense. At Independent Electric, we encounter this scenario regularly with motors above 600 horsepower. When core testing shows the iron has too much loss measured in watts pe

When a critical electric motor fails in your facility, the clock starts ticking. Every hour of downtime costs money, and the pressure to make the right decision—fast—is intense. Should you repair the motor? Does it need a complete rewind? Or replace it entirely? This isn’t just a maintenance question. It’s a strategic decision that impacts your operating budget, production reliability, and long-term equipment performance. Make the wrong call, and you might waste money on a re

"Do the noise for us." That was a running gag on NPR's Car Talk, where the Magliozzi brothers from Boston diagnosed car problems based on callers trying to imitate the sounds their vehicles made. "Is it more of a 'click-click-click' or a 'thunk-thunk-thunk'?" they'd ask, somehow extracting diagnostic gold from amateur sound effects over the phone. The sounds your motor makes can indicate what's failing inside if you know how to listen. Electrical problems sound different from

It’s music to your ears as you walk the floor at your facility: the steady hum of motors keeping production running. But what happens when that hum changes? When vibration increases just slightly? When a bearing starts making noise that's not quite right? Motors don't just fail overnight. They give you warnings. The question is: are you reading the signs? At Independent Electric, we've spent over 100 years helping Midwest manufacturers avoid catastrophic motor failures. And h
