Tips: Difference between stepper motor and DC motor

The difference between stepper motor and DC motor in nature is that the DC motor can directly convert current into mechanical energy, and the stepper motor cannot transfer the current. The stepper motor controls the normal operation of the motor through pulse signal conversion, and the controlled objects are different between the two.

The hybrid stepper motor guarantees the rotation of the stepper motor by inputting electric pulses. The input of electric pulses urges angular displacement or linear displacement to ensure that the number of pulses is proportional to the speed and frequency. If the winding direction is opposite, the direction of rotation of the motor will also be opposite. Control the rotation of the bipolar stepper motor by controlling the number of pulses and the direction of the winding.

The DC motor is relatively simple. The armature is mainly powered by brushes. The surface current of the points is mainly consistent with the direction of the armature. The armature is mainly divided into N-pole and S-pole lower conductors. The conductor is guaranteed according to the left-hand rule. Be affected. In this way, the electrical windings of the entire DC motor will rotate, and then the DC electrical energy will be converted into mechanical energy.
