Re: High or Low voltage steppers better for Gecko

I like the 1 volt as it is easier to get a power supply in the lower
voltage ranges.

you might want to considder

PING

as an option if they still have them
http://www.herbach.com if you don't like cutting and pasting.
motors on the left, then stepper motors, then page 4

back to your stiutation
20 times nameplate for the voltage
1 x 20 = 20 volts.
4.5 x 20 = 90 volts (20 volts too high)
7.2 volts limits you to the 70 max for a Gecko.

just an idea.
