Background
The stepping motor is composed of an iron core, a coil and the like. When the coil is electrified, magnetic force is generated to push the iron core rotor to move and output to rotate for an angle, so that the output rotating shaft is kept at a new working position; the coil is electrified again, and the rotating shaft rotates by an angle again to perform stepping motion in sequence. Magnetic lines of force are generated by the permanent magnet and the stator coil of the rotor, when the motor is not electrified, the rotor is rotated, the coil of the stator can cut the magnetic lines of force of the rotor to generate current, the rotor can be understood as an equivalent generator, and at the moment, the current of the stator coil of the short-circuit stepping motor can generate a reverse magnetic field to generate resistance. The reason why the short circuit of the motor wire can not burn out the coil is that the stepping motor stops rotating very fast after the short circuit of the coil and can not generate electricity, so the stepping motor can not be burnt out. However, if the coil is short-circuited, the coil still needs to be burnt out by external force when the stepping motor runs for a long time.
