Friends, I need advice on how to design and power up 26 Variable Frequency AC Motor Drives in an electrical room with 480 volt power available. They vary in size from 0.5 to 25 horsepower. Should I put them all in a Motor Control Center? How do I isolate & filter so that noise does not get back onto the 480 Volt power supply? What filtering devices should I use for this many drives? Is it more practical to buy individual wall-mount drive units, with an isolation power feed transformer?
