DC motor is a type of electric motor that converts DC electrical energy into mechanical energy, and it has a wide range of applications in industrial production and daily life.

1、 Basic concepts

Definition: A DC motor refers to a rotating electrical machine that can convert DC electrical energy into mechanical energy (DC motor) or convert mechanical energy into DC electrical energy (DC generator). When it operates as an electric motor, it converts electrical energy into mechanical energy; When operating as a generator, convert mechanical energy into electrical energy.

Main components: The DC motor is mainly composed of stator, rotor (armature), brush device, and other parts. Among them, the rotor (armature) is the hub for energy conversion in DC motors, consisting of the shaft, armature core, armature winding, commutator, and fan.

2、 Working principle

The working principle of a DC motor is based on the law of electromagnetic induction. When a DC power supply supplies power to the armature winding through electric brushes, current is generated in the conductors on the surface of the armature. These currents will be subjected to force under the action of the stator magnetic field, causing the armature (rotor) to start rotating. At the same time, the commutator will promptly change the direction of the current in the armature winding to maintain the continuous rotation of the armature. In this way, the input DC electrical energy is converted into mechanical energy output on the rotor shaft.

3、 Classification

DC motors can be classified according to different standards, such as permanent magnet excitation, separate excitation, and self excitation, with self excitation further divided into parallel excitation, series excitation, and compound excitation. Different types of DC motors have differences in performance and application.

4、 Advantages

Good torque characteristics: The relationship between the speed and torque of a DC motor is relatively simple and clear, making it easy to achieve speed regulation and load balancing.

Convenient starting and reversing: DC motors have good starting and reversing capabilities, which can accelerate from a stationary state to a set speed in a short time, and reverse rotation is also very easy to achieve.

Easy to control: As DC motors can control their output torque and speed through current control, their operating status can be precisely controlled, including various parameters such as speed and torque.

Efficient and energy-saving: DC motors are high-efficiency motors with characteristics such as high efficiency, low power consumption, low noise, and low vibration, which can achieve high-quality and high-performance power output.

5、 Disadvantages

Short lifespan of electric brushes: DC motors use electric brushes for power supply, and the wear of the brushes is severe, resulting in a short lifespan.

High maintenance costs: Due to the complex structure and brush wear of DC motors, their repair and replacement costs are relatively high.

Electromagnetic interference: DC motors generate significant electromagnetic interference during operation, which may have a negative impact on surrounding electronic devices.

DC power supply required: As DC motors require DC power supply to function properly, a separate DC power supply is needed, which increases costs and difficulty of use.
