We still use electromechanical frequency converters in our production. I thought about replacing them with solid-state. Has anyone really felt the difference? Is it worth the candle, especially if the equipment is old?

We switched two years ago - no brushes, no vibrations, and most importantly - almost zero maintenance. Yes, it's a bit expensive at the start, but then it pays off due to stability and less downtime.

We went through this transition at our production facility a couple of years ago. The old motor generators constantly required attention: brushes, noise, heat, and dimensions. We switched to solid-state ones - we chose one of the solid state frequency converters from 50hz. I can assure you that the difference is noticeable: stable output frequency, almost zero start-up delay, quiet operation, and no vibration. We didn't have to replace all of our equipment - just the converter itself - and even the old machines started running more smoothly. So yes, the transition was worth it, especially if reliability and parameter control are important.
