I have a small brushed DC electric motor which I think is only rated for 5-9 volts, but the seller claims 5-12 volts. I gave it 12 volts for some seconds and after I stopped to switch to 5 volts, the motor seems to have an internal short circuit.
Is this the normal failure mode for an electric motor when gives too high voltage? I thought it should burn over the brushes and show an open circuit. Why is the circuit shorted internally when it fails?
