Q. Will a DC motor really produce voltage if it is spun in reverse?
Answer:-
It will produce voltage if you spin it forwards too. The merely difference between a DC motor and a DC generator is what you utilize it for. A long time previously cars had DC generators on them instead of AC alternators. When you change a generator you had to "polarize" it consequently it would make electricity. You enthusiastic it up to your battery and let it run as a motor for a few seconds. Do not try that with an alternator for the reason that you'll break it. If you're seem to be for a neat little elementary-school science project you can use little Radio Shack electric motors as generators for things like water wheels, windmills, dynamos turned by bicycle tires.
