    Hello,I took apart 3.5 in floppy drive and salvaged it's stepper motor for one project.The problem is after I hook it up to arduino and L293 it will run for few seconds and suddenly stall(I'm pretty sure it stalls after finishing one revolution and then stalls in step mode) after stalling I have to move the shaft to make it rotate but it stall's again after few moments. I'm powering it from USB port (5V-500mA max.).Does anyone know at what voltage do this small steppers work?Could it be stalling because it need's higher voltage?

    Likely, the USB port cannot supply enough current...

    Are you sure that you are producing the right sequence to drive it continuously? Have you checked that?
