Isn't that basically what your calculation is based on though? It's 60 amps in both calculations, but the 2 motor setup is putting out less torque at a higher RPM.
I realize that load isn't a constant when you're talking about acceleration, but there are situations where a single motor would be more efficient.
Aside from limiting inrush current you could never *decide* that you're going to apply 60 amps to a running motor who's continuous load only requires 20 amps.
If I had a windows machine I'd mess around with mcalc, looks like a nifty program
