The power of the DC micro gear motor comes from the DC motor, and the application of the DC motor is also very extensive. However, many people do not know much about the DC motor. Here, the editor of Kehua explains the structure, performance and Advantages and disadvantages.

1. Definition, a DC motor is a motor that obtains electrical energy through direct current and converts the electrical energy into rotating mechanical energy.

Second, the structure of the DC motor, first of all, the DC motor is composed of a stator and a rotor, the stator includes a base, a main magnetic pole, a commutation pole, and a brush, and the rotor includes an iron core, a winding, a commutator, and an output shaft.

Third, the working principle of the DC motor, when the DC motor is energized, the DC power supply supplies power to the armature winding through the brush, and the armature N-pole conductor can flow current in the same direction. According to the left-hand law, the conductor will be subjected to counterclockwise torque action The armature S pole conductor will also flow current in the same direction, and the entire armature winding will rotate, converting the input DC electrical energy into mechanical energy

Fourth, the advantages of DC motor, good control performance, wide speed adjustment range, relatively large torque, mature technology, relatively low cost

Fifth, the shortcomings of DC motors, the brushes are prone to problems, the service life is relatively short, and the maintenance cost is relatively high.

With the increasing application of miniature geared motors in smart products, many of these smart products belong to fast-moving consumer electronics products. Fast-moving consumer products pursue the characteristics of low cost and relatively short lifespan. Therefore, DC motors have become The motor of choice for consumer smart products.
