How do Stepper Motor Drivers Overcome the Speed Restrictions Due to a Charging Coil?

(**Notes on Supply Voltages in the table: I used 68V for the NEMA 23 because that's what I'm using even though it's 20% above maximum recommended. The 77.78V NEMA 34 values are RMS values of the specified 110Vac shown in their datasheets. I figured this would be a reasonable DC value to use. I chose 48V for the 3.4Nm because 77.78V seemed way too high.)

Are you sure the 110V AC figure isn't a RMS value to start with? It's the normal was to quote an AC voltage unless you specifically say "110V AC pk" - anyway it does say also 5.9A constant current, so the voltage is kind of irrelevant.
