[SML] Motors on UPSs

[bruce at ledworklights.com]

Has anyone ever put motors on UPS/battery backup?

The project I'm working on has two 8,000 pound motion bases, they each use
6 motors and draw 60 amps per base at 220V 3 phase. Here's a sample

Look at online, double-conversion UPS if this is a true concern. 
Essentially a giant rack of battery chargers, a room full of batteries, and
Sine-wave Inverters.  The load is ALWAYS on battery power, essentially. 
No, you can't buy it off the shelf at Best Buy, but yes, they are/can be
engineered for motor loads.
