what happens when you put 12v into a 24v stepper motor?

This may be a dumb question, but if I have a stepper motor that says
it is 24 volts.... will it work ( slow is ok ) if I only apply 12 volts
to the coils? I only need about 270 deg of rotation from it and I will
drive it fairly slowly ( in case that matters )

Thanks - jack

 

My impression is that you will get much less power out of it. It may barely
move at all. But the speed shouldn't be impacted if you can get it to
move, as the stepper motor is designed to move a specific amount with one
pulse.

It will produce half (or a little less) of rated torque, and the
maximum speed will be quite slow. Dozens of steps per second,
perhaps. It will also pass only about half of its rated current, and
run quite cool.
