Can I drive stepper motor with AC voltage?
The motor specification in your second link is very badly wrong. The data sheet provided by the website page is for a 24 volt DC stepper motor, as shown on page 6. However, further down the data sheet a system diagram is shown which suggests the use of an AC to DC power supply with an input of 100 to 240 VAC - that is, just about any AC voltage you'll find in the world. So the description is badly misleading. Why they called it a 100 VAC stepper is impossible to say, but a major brain fart by whoever created the web page is a good bet.

The linked datasheet is correct, and as it states, the nominal operating conditions are 4 amps at 1.4 volts. That is, it's a bipolar stepper with 0.65 ohm windings and a nominal maximum of 2 amps per winding. In order to drive it, you would want a standard bipolar driver with that capability. If you apply 24 volts, unless the power supply is current limited to 2 amps you will burn out the motor.
