VFD used with either a 3~ Rotary Converter or Phase Inverter
One of RCMs frequent responders noted his starting current on a large RPC to
be 120 amps. Get real! Locked rotor current (starting current) of a 17 HP
motor on single phase would be in the neighborhood of 300 - 400 amps;
probably more when starting a 3-phase motor on single-phase. The OP
probably tried to read the maximum "kick" observed on a clamp-on amp meter,
and was oblivious to the effects of meter "ballistics".

Forgot to say, when I start the 10 HP idler in my 17.5 HP dual idler
RPC, the starting current is 120 amps.
