Hang on a minute here, folks. Starting inrush current on most NEMA and IEC motors is six to eight times FLA when started across the line. That's current that has to be available from the AC supply for at least a couple of seconds minimum. On high inertia load like flywheels, centrifuges, and fans, this inrush can last ten's of seconds.
The question for awalinski is whether his supply system can supply that level of current for the time required. In most industrial facilities there would be no problem but, it bears checking. It's not the first time I've seen a motor starter close and a bunch of other smaller starters drop out and all the flourescent bulbs in the building go out and then relight.
If the system for whatever reason cannot bear this inrush condition, then soft-starting can help if the load is capable of being soft-started. Remember, the degree of soft-starting available is determined solely by the load.
Finally, that 60hp 103amp nameplate on the motor is suspicious. As pointed out above, it clearly is not a 230 or 460V rating. Is it possible that this is a 380V 50Hz motor? And, if so, how are you reconciling this rating to North American 60Hz power, normally 230, 460, or 575V?
