DC motor is a common type of electric motor, which is characterized by simple structure, reliable operation and wide range of speed adjustment. Therefore, it is widely used in industrial production and household appliances. The working principle of DC motor is to utilize DC current to generate torque in the magnetic field, thus driving the motor to rotate. According to different applications and working requirements, DC motors can be divided into two types: permanent magnet DC motors and brush DC motors.

Permanent magnet DC motors have the advantages of simple structure, small size, large starting torque and fast response speed. It is suitable for the occasions that need fast starting and precise control, such as household appliances, automation equipment and so on. While brush DC motor has a greater power density and torque density, suitable for the need for high-power output and precision control occasions, such as industrial production of lifting equipment, machine tools and so on.

In modern industrial production, DC motor through continuous technological innovation and improvement. It already has a high efficiency, energy saving, low noise and other characteristics. It can meet the needs of a variety of complex working conditions. At the same time, with the development of electronic technology, DC motor control system has become more intelligent and precise. It can realize precise speed and torque control and improve the stability and reliability of the equipment.

In conclusion, DC motor as a mature type of motor with a variety of models and specifications, which can meet the needs of different fields. It is one of the important equipment indispensable to modern industrial production.
