Tell me about it, I am a maintenance supervisor at a concrete batching plant, the owners many years ago thought they were getting a bargain at an auction of some European machinery, I had to replace all the motors.

And then I modernized the whole plant to use 480V 3 phase as the cables and magnetic switches for 208 would have been too massive for a 100hp motor, I love 480 3ph. so simple to motor reverse, wires and switches much smaller.

Retired a few years now, but I used to work on 400hz 200v 3Φ AC generators for the computer systems I worked with. Smaller everything, especially the wires. In the 20+ years I worked on them, we never had one that failed in service. We did have a tech out west that replaced the bearings backwards - tore up the shaft as well as the bearings. Replaced them and had a full recovery. Good units and equipment all around.
