Dear All
Please help me to know timing driver this stepper motor (in DVD )4 wires.
Thank you so much.
 

4 wires suggest a standard bipolar 2-phase scheme. You need two full bridge drivers to supply it.

=======================================
You can use 5vdc to 9vdc but motor is started working at 3vdc. But if your motor is warm(normal is not warm) please checked the timing driver. Thank you
