DC motor structure characteristics and working principle
A DC motor is a rotating electrical machine that converts DC electrical energy into mechanical energy (DC motor) or converts mechanical energy into DC electrical energy (DC generator). It is a motor that converts DC power and mechanical energy to each other. When it is used as a motor, it is a DC motor that converts electrical energy into mechanical energy; when the generator is running, it is a DC generator that converts mechanical energy into electrical energy.

DC motor structure features: It should be composed of two parts: stator and rotor. The part of the DC motor that is stationary during operation is called the stator. The main function of the stator is to generate a magnetic field. It consists of a base, a main pole, a commutating pole, an end cover, a bearing and a brush device. The part that rotates during operation is called the rotor. Its main function is to generate electromagnetic torque and induced electromotive force. It is the pivot of energy conversion of DC motor, so it is usually called armature. It is changed by shaft, armature core, armature winding, and It consists of a transmitter and a fan.
Working principle of DC motor: The DC motor is fixed with a ring-shaped permanent magnet inside. The current generates ampere force through the coil on the rotor. When the coil on the rotor is parallel to the magnetic field, the direction of the magnetic field will continue to change, so the rotor end The brush is in alternating contact with the converter, so that the direction of the current on the coil also changes, and the direction of the Lorentz force is constant, so the motor can maintain one direction of rotation.
DC motors are often used in agitator motors. High Speed Blender Motor is our hot product.
