em 319 stepper

hi
i just bought em 319 stepper motor, does anyone know its spec. is it operatable by A4988 driver??
please help

EM319 will be the size, you need the full part number to know the winding details,
assuming they are publically documented at all.

From google it seems this is a printer bipolar stepper. The first thing to determine
is the winding resistance and step count. Multimeter will give you the first, passing a
current through one of the windings and counting the number of cogging steps round
360 degrees will tell you the number of steps divided by 4. Such motors are often
24 steps or something like that. The winding resistance will determine if its a good
candidate for a chopper driver and if so what voltage is needed.

is it operatable by A4988 driver

Yes
