The windings melt. Also may start a fire if surround conditions permit.

The electric motor changes electric energy into mechanical energy.
the voltage tolerance of a standard electric motor is
An electric motor converts electrical energy to kinetic energy.
I HAVE A SMALL ELECTRIC CLOCK MOTOR THAT I NEED TO REVERSE. WHAT IS THE CIRCUIT I NEED TO REVERSE IT?
It makes the motor run insufficiently.
Beats me
Assuming you mean electric motors, the causes for failure include seized bearings and worn brushes. If the bearings or bushings are seized, the motor may fail. Most electric fans have thermal fuses, so if the motor seizes and overheats, the fuse blows. If the brushes are worn, then the motor is no receiving electricity and thus cannot turn.

You didn't say what type of motor. If an electric motor it could be the shaft bearing(s) are worn.
It Gets hot
Electric motor
it is probably your water pump
fuse wire overheats and melts in plug and cuts off the supply of electric current.
